| 4 | Manipulation of SlMXl for enhanced carotenoids accumulation and drought resistance in tomato显示文摘Plants are the ultimate source of nutrients in the human diet. To ensure adequate availability of high quality food for an increasing world population, traits including improved tolerance of stresses and nutrient levels need to be selected in crops, both individually and in combination. Here we report the identification of Sl MX1 encoding a MIXTA-like MYB transcription factor in tomato that simultaneously modulates drought resistance and metabolic processes through regulating key structural and regulatory genes of the corresponding pathways. Over-expression of Sl MX1 results in substantially increased drought tolerance and improved fruit quality, while knocking down Sl MX1 resulted in the opposite phenotypes. Our study indicates an effective way with multiple beneficial traits by genetic engineering of a single regulatory gene and can be a novel approach to breeding crops. | Mohamed Ewas Yanqiang Gao Shouchuang Wang Xianqing Liu Hongyan Zhang Elsayed M.

| 5 | Comprehensive profiling and natural variation of flavonoids in rice显示文摘Flavonoids constitute a major group of plant phenolic compounds.While extensively studied in Arabidopsis,profiling and naturally occurring variation of these compounds in rice(Oryza sativa),the monocot model plant,are less reported.Using a collection of rice germplasm,comprehensive profiling and natural variation of flavonoids were presented in this report.Application of a widely targeted metabolomics method facilitated the simultaneous identification and quantification of more than 90 flavonoids using liquid chromatography tandem mass spectrometry(LC-MS/MS).Comparing flavonoid contents in various tissues during different developmental stages revealed tissue-specific accumulation of most flavonoids.Further investigation indicated that flavone mono-C-glycosides,malonylated flavonoid O-hexosides,and some flavonoid O-glycosides accumulated at significantly higher levels in indica than in japonica,while the opposite was observed for aromatic acylated flavone C-hexosyl-O-hexosides.In contrast to the highly differential accumulation between the two subspecies,relatively small variations within subspecies were detected for most flavonoids.Besides,an association analysis between flavonoid accumulation and its biosynthetic gene sequence polymorphisms disclosed that natural variation of flavonoids was probably caused by sequence polymorphisms in the coding region of flavonoid biosynthetic genes.Our work paves the way for future dissection of biosynthesis and regulation of flavonoid pathway in rice. | Xuekui Dong Wei Chen Wensheng Wang Hongyan Zhang Xianqing Liu Jie Luo | 2014 | Journal of Integrative Plant Biology2014，56，9： | 8 |
| 6 | Structural and biochemical mechanism for increased infectivity and immune evasion of Omicron BA.2 variant compared to BA.1 and their possible mouse origins显示文摘The Omicron BA.2 variant has become a dominant infective strain worldwide.Receptor binding studies show that the Omicron BA.2 spike trimer exhibits 11-fold and 2-fold higher potency in binding to human ACE2 than the spike trimer from the wildtype(WT)and Omicron BA.1 strains.The structure of the BA.2 spike trimer complexed with human ACE2 reveals that all three receptor-binding domains(RBDs)in the spike trimer are in open conformation,ready for ACE2 binding,thus providing a basis for the increased infectivity of the BA.2 strain.JMB2002,a therapeutic antibody that was shown to efficiently inhibit Omicron BA.1,also shows potent neutralization activities against Omicron BA.2.In addition,both BA.1 and BA.2 spike trimers are able to bind to mouse ACE2 with high potency.In contrast,the WT spike trimer binds well to cat ACE2 but not to mouse ACE2.The structures of both BA.1 and BA.2 spike trimer bound to mouse ACE2 reveal the basis for their high affinity interactions.Together,these results suggest a possible evolution pathway for Omicron BA.1 and BA.2 variants via a human-cat-mouse-human circle,which could have important implications in establishing an effective strategy for combating SARS-CoV-2 viral infections. | Youwei Xu Canrong Wu Xiaodan Cao Chunyin Gu Heng Liu Meriting Jiang Xiaoxi Wang Qingning Yuan Kai Wu Jia Liu Deyi Wang Xianqing He Xueping Wang Su-Jun Deng H.Eric Xu Wanchao Yin | 2022 | Cell Research2022，32，7： | 6 |
| 7 | A UV-B-responsive glycosyltransferase,OsUGT706C2,modulates flavonoid metabolism in rice显示文摘Although natural variations in rice flavonoids exist, and biochemical characterization of a few flavonoid glycosyltransferases has been reported, few studies focused on natural variations in tricin-lignan-glycosides and their underlying genetic basis. In this study, we carried out metabolic profiling of tricin-lignan-glycosides and identified a major quantitative gene annotated as a UDPdependent glycosyltransferase OsUGT706C2 by metabolite-based genome-wide association analysis. The putative flavonoid glycosyltransferase OsUGT706C2 was characterized as a flavonoid 7-O-glycosyltransferas in vitro and in vivo. Although the in vitro enzyme activity of OsUGT706C2 was similar to that of OsUGT706D1, the expression pattern and induced expression profile of OsUGT706C2 were very different from those of OsUGT706D1. Besides, OsUGT706C2 was specifically induced by UV-B. Constitutive expression of OsUGT706C2 in rice may modulate phenylpropanoid metabolism at both the transcript and metabolite levels. Furthermore, overexpressing OsUGT706C2 can enhance UV-B tolerance by promoting ROS scavenging in rice. Our findings might make it possible to use the glycosyltransferase OsUGT706C2 for crop improvement with respect to UVB adaptation and/or flavonoid accumulation, which may contribute to stable yield. | Feng Zhang Hao Guo Jiacheng Huang Chenkun Yang Yufei Li Xuyang Wang Lianghuan Qu Xianqing Liu Jie Luo | 2020 | Science China(Life Sciences)2020，63，7： | 5 |
| 8 | Fluid inclusion evidence for petroleum accumulation in northern Qaidam Basin显示文摘Based on the results of fluid inclusion study(microscopic characteristics,homogenization temperatures and grains with oil inclusions),the pool-forming time of the Nanbaxian and Mabei 1 oilfields in northern Qaidam Basin was discussed in this paper.Fluid inclusions in northern Qaidam Basin are relatively abundant,including aqueous inclusions and hydrocarbon inclusions.These inclusions are small(5-10 μm),and mainly distributed in quartz fissures,overgrowths and cementations.The abundances of grains with oil inclusions(GOI) are commonly low.The GOI values of most samples are between 2.0%-10.5%,and those of about 40 percent of total samples exceed 5%.The homogenization temperatures of fluid inclusions in different samples are markedly dissimilar,indicating that these inclusions were formed in different periods.According to the measured homogenization temperatures of fluid inclusions and in combination with burial history and thermal evolution history,the Nanbaxian and Mabei 1 oilfields are deduced,which have experienced two hydrocarbon charging periods,with the former of N1-N21 and N22-N23,and the latter of N1 and N1 end-N2,respectively. | YANG Yunfeng LI Xianqing FENG Songbao WANG Kangdong KONG Longxi DONG Peng XU Feng PENG Dehua CHEN Yan | 2010 | Chinese Journal Of Geochemistry2010，29，4： | 5 |
| 9 | Potential association of long noncoding RNA HA117 with tetralogy of Fallot显示文摘Tetralogy of Fallot(TOF)is a congenital heart disease characterized by abnormal cardiomyocyte differentiation in the right ventricular outflow tract(RVOT),and HA117 is a novel long noncoding RNA(lncRNA)with anti-differentiation roles.To investigate the potential association of HA117 with TOF,we collected 84 RVOT tissues from patients with TOF.We determined the expression of HA117 in RVOT samples from TOF patients and collected clinical data to conduct a cross-sectional and short-term follow-up study.McGoon ratio,Nakata index,and left ventricular end-diastolic volume index(LVEDVI)were negatively correlated with the expression of HA117 based on subgroup analysis,correlation analysis and logistic regression analysis.Additionally,cardiopulmonary bypass(CPB)time and ICU stay were longer in patients with higher expression of HA117 than in patients with lower expression of HA117.Furthermore,percentage improvement in SPO2 was significantly reduced in patients with increased HA117 expression at 6 months after surgery.Our results suggested that the increased expression of the novel lncRNA HA117 is a risk factor for unfavorable McGoon ratio,Nakata index and LVEDVI in TOF patients.Additionally,an increased expression of HA117 might lead to adverse short-term outcomes in TOF patients. | Quan Wang Zhili Wang Chun Wu Zhengxia Pan Li Xiang Hang Liu Xin Jin Kerong Tong Shulei Fan Xianqing Jin | 2018 | Genes & Diseases2018，5，2： | 5 |
| 10 | Las-like quorum-sensing system negatively regulates both pyoluteorin and phenazine-1-carboxylic acid production in Pseudomonas sp. M18显示文摘A las-like quorum-sensing system in Pseudomonas sp. M18 was identified, which consisted of lasI and lasR genes encoding LuxI-LuxR type regulator. Several functions of the las system from strain M18 were investigated in this study. The chromosomal inactivation of either lasI or lasR by recombination increased the production of both pyoluteorin (Plt) and phenazine-1-carboxylic acid (PCA) by 4-5 fold and 2-3 fold over that of the wild type strain of M18, respectively. Production of both antibiotics was restored to wild-type levels after in trans complementation with the wild-type lasI or lasR gene. Expression of the translational fusions pltA'-'lacZ and phzA'-'lacZ further confirmed the negative effect of lasI or lasR on both biosynthetic operons, and it was also demonstrated that the las system was related to the ability of swarming motility and the inhibition of cell growth. | CHEN Yun, WANG XiaoLei, HUANG XianQing, ZHANG XueHong & XU YuQuan Key Laboratory of Microbial Metabolism of Ministry of Education, College of Life Sciences and Biotechnology, Shanghai Jiao Tong University, Shanghai 200240, China | 2008 | Science China(Life Sciences)2008，51，2： | 5 |
| 11 | Lipid Oxidation and Fatty Acid Composition in Salt-Dried Yellow Croaker(Pseudosciaena polyactis) During Processing显示文摘Lipid oxidation in salt-dried yellow croaker(Pseudosciaena polyactis) was evaluated during processing with commonly used analytical indices, such as the peroxide value(POV), the thiobarbituric acid reactive substances(TBARS) value, and oxidative-relative lipoxygenase(LOX) activity. Additionally, fatty acids were analyzed using gas chromatography-mass spectrometry. Both POV and TBARS increased significantly(P < 0.05) at the rinsing stage. POV reached its peak value of 3.63 meq O_2 per kg sample at the drying stage, whereas TBARS constantly increased from 0.05 to 0.20 mg MDA per kg sample. Processing of salt-dried yellow croaker had an extremely significant(P < 0.01) effect on LOX activity. Twenty-six fatty acids were identified. Combined eicosapentaenoic acid(EPA; C20:5n3) and docosahexaenoic acid(DHA; C22:6n3) content varied between(19.20 ±0.37) mg g^(-1) and(23.45 ± 1.05) mg g^(-1). The polyunsaturated fatty acid/saturated fatty acid(PUFA/SFA) ratio in yellow croaker was 0.73–1.10, and the n-6/n-3 PUFA ratio was approximately 0.13–0.20. The contents of most fatty acids varied significantly(P <0.05) during the different processing stages, and these differences were caused by lipid oxidation. C18:0, C16:1n7, C19:0, and C22:6n3 showed clear changes in principle component one of a principle components analysis. These fatty acids are potential markers for evaluating lipid oxidation in fish muscle because there was a significant correlation between these markers and TBARS and LOX activity(P < 0.05) with Pearson's coefficients > 0.931. | CAI Qiuxing WU Yanyan LI Laihao WANG Yueqi YANG Xianqing ZHAO Yongqiang | 2017 | Journal of Ocean University of China2017，16，5： | 5 |
| 12 | Ethylene and salicylic acid synergistically accelerate leaf senescence in Arabidopsis显示文摘The phytohormones ethylene and salicylic acid(SA) have long been known to promote senescence, but their interplay during this process remains elusive. Here we report the synergistic effects of ethylene and SA on promoting leaf senescence in Arabidopsis. EIN3, a key transcription factor of ethylene signaling, physically interacted with the core SA signaling regulator NPR1 in senescing leaves. EIN3 and NPR1 synergistically promoted the expression of the senescence-associated genes ORE1 and SAG29.The senescence phenotype was more delayed for the ein3 eil1 npr1 triple mutant than ein3 eil1 or npr1 with ethylene or/and SA treatment. NPR1-promoted leaf senescence may depend on functional EIN3/EIL1. | Chaoqi Wang Shouyi Dai Zhong‐Lin Zhang Wenqing Lao Ruiying Wang Xianqing Meng Xin Zhou | 2021 | Journal of Integrative Plant Biology2021，63，5： | 4 |
| 13 | The tectonic differences between the east and the west in the deep-water area of the northern South China Sea显示文摘The deep-water area of the northern South China Sea, which has active and complicated tectonics, is rich in natural gas and gas hydrate. While the tectonic characteristics is different obviously between the east and the west because of the special tectonic position and tectonic evolution process. In terms of submarine geomorphology,the eastern shelf-slope structure in Pearl River Mouth Basin is characterized by having wide sub-basins and narrow intervening highs, whereas the western(Qiongdongnan Basin) structure is characterized by narrow subbasins and wide uplift. As to the structural features, the deep-water sags in the east are all structurally halfgrabens, controlled by a series of south-dipping normal faults. While the west sags are mainly characterised by graben structures with faulting in both the south and north. With regards to the tectonic evolution, the east began neotectonic activity when the post-rifting stage had completed at the end of the Middle Miocene. In the Baiyun Sag, tectonic activity became strong and was characterised by rapid subsidence and obvious faulting. Whereas in the west, neotectonic activity began at the end of the Late Miocene with rapid deposition and weak fault activity. | XIA Zhongyu WAN Zhifeng WANG Xianqing SHI Qiuhua CAI Song XIA Bin | 2016 | Acta Oceanologica Sinica2016，35，1： | 4 |
| 14 | A targeted sequencing approach to find novel pathogenic genes associated with sporadic aortic dissection显示文摘Aortic dissection(AD) is a heterogeneous genetic disease of the aorta with high mortality and poor prognosis. However, only few genetic causes of AD have been explored till date. After conducting a broad literature review focused on identifying potential pathogenic pathways, we designed a panel containing 152 AD-associated genes to conduct massively parallel targeted nextgeneration sequencing of 702 sporadic aortic dissection patients and 163 matched healthy controls. After validation by Sanger sequencing, we identified 21 definitely pathogenic and 635 likely pathogenic variants in 61.25%(430/702) of patients. In these patients, 34.88%(150/430) harbored more than one variant that was either definitely or likely to be pathogenic. Among the candidate genes, we identified 546 likely pathogenic variants in 47.72%(335/702) of patients. Importantly, we identified 94 lossof-function(LOF) variants in 45 genes in AD patients, but only five LOF variants in the controls(P=1.34×10^(-4)). With a burden test, we highlighted RNF213 as an important new gene for AD pathogenesis. We also performed transcriptome sequencing of human aorta tissues to evaluate the expression levels of these newly identified genes. Our study has compiled a comprehensive genetic map of sporadic AD in the Han Chinese population. We believe it will facilitate risk predicting and genetic diagnosis of this severe disease in the future. | Zongzhe Li Chengming Zhou Lun Tan Peng Chen Yanyan Cao Xianqing Li Jiangtao Yan Hesong Zeng Dao-Wu Wang Dao-Wen Wang | 2018 | Science China(Life Sciences)2018，61，12： | 4 |
| 15 | Highly Selective Biomimetic Flexible Tactile Sensor for Neuroprosthetics显示文摘Biomimetic flexible tactile sensors endow prosthetics with the ability to manipulate objects,similar to human hands.However,it is still a great challenge to selectively respond to static and sliding friction forces,which is crucial tactile information relevant to the perception of weight and slippage during grasps.Here,inspired by the structure of fingerprints and the selective response of Ruffini endings to friction forces,we developed a biomimetic flexible capacitive sensor to selectively detect static and sliding friction forces.The sensor is designed as a novel plane-parallel capacitor,in which silver nanowire-3D polydimethylsiloxane(PDMS)electrodes are placed in a spiral configuration and set perpendicular to the substrate.Silver nanowires are uniformly distributed on the surfaces of 3D polydimethylsiloxane microcolumns,and silicon rubber(Ecoflex^(■))acts as the dielectric material.The capacitance of the sensor remains nearly constant under different applied normal forces but increases with the static friction force and decreases when sliding occurs.Furthermore,aiming at the slippage perception of neuroprosthetics,a custom-designed signal encoding circuit was designed to transform the capacitance signal into a bionic pulsed signal modulated by the applied sliding friction force.Test results demonstrate the great potential of the novel biomimetic flexible sensors with directional and dynamic sensitivity of haptic force for smart neuroprosthetics. | Yue Li Zhiguang Cao Tie Li Fuqin Sun Yuanyuan Bai Qifeng Lu Shuqi Wang Xianqing Yang Manzhao Hao Ning Lan Ting Zhang | 2020 | Research2020，，1： | 4 |
| 16 | Variants of genes encoding collagens and matrix metalloproteinase system increased the risk of aortic dissection显示文摘Aortic dissection(AD) is a devastating,heterogeneous condition of aorta.The homeostasis between collagens and matrix metalloproteases(MMPs)/tissue inhibitors of MMPs(TIMPs) system in the extracellular matrix plays an important role for structure and functions of aorta.However,our knowledge on association between variants of genes in this system and pathogenesis of AD is very limited.We analyzed all yet known coding human genes of collagens(45 genes),MMPs/TIMPs(27genes) in 702 sporadic AD patients and in 163 matched healthy controls,by using massively targeted next-generation and Sanger sequencing.To define the pathogenesis of potential disease-causing candidate genes,we performed transcriptome sequencing and pedigree co-segregation analysis in some genes and generated Col5a2 knockout rats.We identified 257 pathogenic or likely pathogenic variants which involved 88.89%(64/72) genes in collagens-MMPs/TIMPs system and accounted for 31.05%(218/702) sporadic AD patients.In them,84.86%patients(185/218) carried one variant,12.84%two variants and 2.30%more than two variants.Importantly,we identified 52 novel probably pathogenic loss-of-function(LOF) variants(20 nonsense,16 frameshift,14 splice sites,one stop-loss,one initiation codon) in 11.06%(50/452) AD patients,which were absent in 163controls(P=2.5×10^(-5)).Transcriptome sequencing revealed that identified variants induced dyshomeostasis in expression of collagens-TIMPs/MMPs systems.The Col5α2^(-/-) rats manifested growth retardation and aortic dysplasia.Our study provides a first comprehensive map of genetic alterations in collagens-MMPs/TIMPs system in sporadic AD patients and suggests that variants of these genes contribute largely to AD pathogenesis. | Zongzhe Li Chengming Zhou Lun Tan Peng Chen Yanyan Cao Chenze Li Xianqing Li Jiangtao Yan Hesong Zeng Dao-Wu Wang Dao-Wen Wang | 2017 | Science China(Life Sciences)2017，60，1： | 4 |
| 17 | Hybrid Three-Dimensional Spiral WSe2 Plasmonic Structures for Highly Efficient Second-Order Nonlinear Parametric Processes显示文摘Two-dimensional(2D)layered materials,with large second-order nonlinear susceptibility,are currently growing as an ideal candidate for fulflling tunable nanoscale coherent light through the second-order nonlinear optical parametric processes.However,the atomic thickness of 2D layered materials leads to poor feld confnement and weak light-matter interaction at nanoscale,resulting in low nonlinear conversion efciency.Here,hybrid three-dimensional(3D)spiral WSe2 plasmonic structures are fabricated for highly efcient second harmonic generation(SHG)and sum-frequency generation(SFG)based on the enhanced light-matter interaction in hybrid plasmonic structures.Te 3D spiral WSe2,with AA lattice stacking,exhibits efcient SH radiation due to the constructive interference of nonlinear polarization between the neighboring atomic layers.Tus,extremely high external SHG conversion efciency(about 2.437×10−5)is achieved.Moreover,the ease of phase-matching condition combined with the enhanced light-matter interaction in hybrid plasmonic structure brings about efcient SHG and SFG simultaneously.Tese results would provide enlightenment for the construction of typical structures for efcient nonlinear processes. | Xianqing Lin Yingying Liu Kang Wang Xiaolong Liu Yongli Yan Yong Jun Li Jiannian Yao Yong Sheng Zhao | 2018 | Research2018，，1： | 4 |
| 18 | Raising the production of phloretin by alleviation of by-product of chalcone synthase in the engineered yeast显示文摘Phloretin is an important skin-lightening and depigmenting agent from the peel of apples. Although de novo production of phloretin has been realized in microbes using the natural pathway from plants, the efficiency of phloretin production is still not enough for industrial application. Here, we established an artificial pathway in the yeast to produce phloretin via assembling two genes of p-coumaroyl-CoA ligase(4CL) and chalcone synthase(CHS). CHS is a key enzyme which conventionally condenses a CoA-tethered starter with three molecules of malonyl-CoA to form the backbone of flavonoids. However, there was 33% of byproduct generated via CHS by condensing two molecules of malonyl-CoA during the fermentation process. Hence, we introduced a more efficient CHS and improved the supply of malonyl-CoA through two pathways;the by-product ratio was decreased from 33% to 17% and the production of phloretin was improved from 48 to 83.2 mg L^(-1). Finally, a fed-batch fermentation process was optimized and the production of phloretin reached 619.5 mg L^(-1), which was 14-fold higher than that of the previous studies. Our work established a platform for the biosynthesis of phloretin from the low-cost raw material 3-(4-hydroxyphenyl) propanoic acid and also illustrated the potential for industrial scale bio-manufacturing of phloretin. | Chunmei Jiang Xiaonan Liu Xianqing Chen Yi Cai Yibin Zhuang Tian Liu Xiaoxi Zhu Hui Wang Yuwan Liu Huifeng Jiang Wen Wang | 2020 | Science China(Life Sciences)2020，63，11： | 3 |
| 19 | Geochemistry, Geochronology and Lu-Hf Isotopes of Peraluminous Granitic Porphyry from the Walegen Au Deposit, West Qinling Terrane显示文摘Walegen Au deposit is closely correlated with granitic intrusions of Triassic age, which are composed of granite and quartz porphyries. Both granite porphyry and quartz porphyry consist of quartz, feldspar and muscovite as primary minerals. Weakly peraluminous granite porphyry(A/CNK=1.10–1.15) is enriched in LREE, depleted in HREE with Nb-Ta-Ti anomalies, and displays subduction-related geochemistry. Quartz porphyry is strongly peraluminous(A/CNK=1.64–2.81) with highly evolved components, characterized by lower TiO_2, REE contents, Mg~#, K/Rb, Nb/Ta, Zr/Hf ratios and higher Rb/Sr ratios than the granite porphyry. REE patterns of quartz porphyry exhibit lanthanide tetrad effect, resulting from mineral fractionation or participation of fluids with enriched F and Cl. LAICP-MS zircon U-Pb dating indicates quartz porphyry formed at 233±3 Ma. The ages of relict zircons from Triassic magmatic rocks match well with the detrital zircons from regional area. In addition, ε_(Hf)(t) values of Triassic magmatic zircons from the granite and quartz porphyries are -14.2 to -9.1(with an exception of +4.1) and -10.8 to -8.6 respectively, indicating a crustal-dominant source. Regionally, numerous Middle Triassic granitoids were previously reported to be formed under the consumption of Paleotethyan Ocean. These facts indicate that the granitic porphyries from Walegen Au deposit may have been formed in the processes of the closing of Paleotethyan Ocean, which could correlate with the arc-related magmatism in the Kunlun orogen to the west and the Qinling orogen to the east. | GUO Xianqing YAN Zhen Jonathan C.AITCHISON FU Changlei WANG Zongqi | 2017 | Acta Geologica Sinica(English Edition)2017，91，6： | 3 |
| 20 | Rice metabolic regulatory network spanning the entire life cycle显示文摘As one of the most important crops in the world,rice(Oryza sativa)is a model plant for metabolome research.Although many studies have focused on the analysis of specific tissues,the changes in metab-olite abundance across the entire life cycle have not yet been determined.In this study,combining both tar-geted and nontargeted metabolite profiling methods,a total of 825 annotated metabolites were quantified in rice samples from different tissues covering the entire life cycle.The contents of metabolites in different tissues of rice were significantly different,with various metabolites accumulating in the plumule and radicle during seed germination.Combining these data with transcriptome data obtained from the same time period,we constructed the Rice Metabolic Regulation Network.The metabolites and co-expressed genes were further divided into 12 clusters according to their accumulation patterns,with members within each cluster displaying a uniform and clear pattern of abundance across development.Using this dataset,we established a comprehensive metabolic profile of the rice life cycle and used two independent strategies to identify novel transcription factors-namely the use of known regulatory genes as bait to screen for new networks underlying lignin metabolism and the unbiased identification of new glycerophospholipid metabolism regulators on the basis of tissue specificity.This study thus demonstrates how guilt-by-association analysis of metabolome and transcriptome data spanning the entire life cycle in cereal crops provides novel resources and tools to aid in understanding the mechanisms underlying important agro-nomic traits. | Chenkun Yang Shuangqian Shen Shen Zhou Yufei Li Yuyuan Mao Junjie Zhou Yuheng Shi Longxu An Qianqian Zhou Wenju Peng Yuanyuan Lyu Xuemei Liu Wei Chen Shouchuang Wang Lianghuan Qu Xianqing Liu Alisdair R.Fernie Jie Luo | 2022 | Molecular Plant2022，15，2： | 3 |
