| 1 | Natural Variation in CCD4 Promoter Underpins Species-Specific Evolution of Red Coloration in Citrus Peel显示文摘Carotenoids and apocarotenoids act as phytohormones and volatile precursors that influence plant development and confer aesthetic and nutritional value critical to consumer preference.Citrus fruits display considerable natural variation in carotenoid and apocarotenoid pigments.In this study,using an integrated genetic approach we revealed that a 5;c/s-regulatory change at CCD4b encoding CAROTENOID CLEAVAGE DIOXYGENASE 4b is a major genetic determinant of natural variation in C3 0 apocarotenoids responsible for red coloration of citrus peel.Functional analyses demonstrated that in addition the known role in synthesizing 3-citraurin,CCD4b is also responsible for the production of another important C3 0 apocarotenoid pigment,p-citraurinene.Furthermore,analyses of the CCD4b promoter and transcripts from various citrus germplasm accessions established a tight correlation between the presence of a putative 5'c/s-regulatory enhancer within an MITE transposon and the enhanced allelic expression of CCD4b in C3 0 apocarotenoid-rich red-peeled accessions.Phylogenetic analysis provided further evidence that functional diversification of CCD4b and naturally occurring variation of the CCD4b promoter resulted in the stepwise evolution of red peels in mandarins and their hybrids.Taken together,our findings provide new insights into the genetic and evolutionary basis of apocarotenoid diversity in plants,and would facilitate breeding efforts that aim to improve the nutritional and aesthetic value of citrus and perhaps other fruit crops. | Xiongjie Zheng Kaijie Zhu Quan Sun Weiyi Zhang Xia Wang Hongbo Cao Meilian Tan Zongzhou Xie Yunliu Zeng Junli Ye Lijun Chai Qiang Xu Zhiyong Pan Shunyuan Xiao Paul D.Fraser Xiuxin Deng | 2019 | Molecular Plant2019，12，9： | 18 |
| 2 | Integration of Metabolomics and Subcellular Organelle Expression Microarray to Increase Understanding the Organic Acid Changes in Post-harvest Citrus Fruit显示文摘Citric acid plays an important role in fresh fruit favor and its adaptability to post-harvest storage conditions.In order to explore organic acid regulatory mechanisms in post-harvest citrus fruit,systematic biological analyses were conducted on stored Hirado Buntan Pummelo(HBP;Citrus grandis)fruits.High-performance capillary electrophoresis,subcellular organelle expression microarray,real-time quantitative reverse transcription polymerase chain reaction,gas chromatography mass spectrometry(GC-MS),and conventional physiological and biochemical analyses were undertaken.The results showed that the concentration of organic acids in HBP underwent a regular fuctuation.GC-MS-based metabolic profling indicated that succinic acid,g-aminobutyric acid(GABA),and glutamine contents increased,but 2-oxoglutaric acid content declined,which further confrmed that the GABA shunt may have some regulatory roles in organic acid catabolism processes.In addition,the concentration of organic acids was signifcantly correlated with senescence-related physiological processes,such as hydrogen peroxide content as well as superoxide dismutase and peroxidase activities,which showed that organic acids could be regarded as important parameters for measuring citrus fruit post-harvest senescence processes. | Xiaohua Sun Andan Zhu Shuzhen Liu Ling Sheng Qiaoli Ma Li Zhang Elsayed Mohamed Elsayed Nishawy Yunliu Zeng Juan Xu Zhaocheng Ma Yunjiang Cheng Xiuxin Deng | 2013 | Journal of Integrative Plant Biology2013，55，11： | 14 |

| 4 | Integrated transcriptomic and metabolomic analyses of a wax deficient citrus mutant exhibiting jasmonic acid-mediated defense against fungal pathogens显示文摘Naturally,resistant crop germplasms are important resources for managing the issues of agricultural product safety and environment deterioration.We found a spontaneous mutant of‘Newhall’navel orange(Citrus sinensis Osbeck)(MT)with broad-spectrum protections against fungal pathogens in the orchard,postharvest-storage,and artificial inoculation conditions.To understand the defense mechanism of MT fruit,we constructed a genome-scale metabolic network that integrated metabolome and transcriptome datasets.The coordinated transcriptomic and metabolic data were enriched in two sub-networks,showing the decrease in very long chain fatty acid(by 41.53%)and cuticular wax synthesis(by 81.34%),and increase in the synthesis of jasmonic acid(JA)(by 95.23%)and JA-induced metabolites such as 5-dimethylnobietin(by 28.37%)in MT.Furthermore,cytological and biochemical analyses confirmed that the response to fungal infection in MT was independent of wax deficiency and was correlated with the levels of jasmonates,and the expression of plant defensin gene PDF1.2.Results of exogenous application of MeJA and JA inhibitors such as propyl gallate proved that JA-mediated defense contributes to the strong tolerance against pathogens in MT.Our results indicated that jasmonate biosynthesis and signaling are stimulated by the fatty acid redirection of MT,and participate in the tolerance of pathogenic fungi. | Yizhong He Jingwen Han Runsheng Liu Yuduan Ding Jinqiu Wang Li Sun Xiaoming Yang Yunliu Zeng Weiwei Wen Juan Xu Hongming Zhang Xiang Yan Zhaoxing Chen Zuliang Gu Hong Chen Huanqing Tang Xiuxin Deng Yunjiang Cheng | 2018 | Horticulture Research2018，5，1： | 8 |

| 6 | Lipidomic and transcriptomic analysis reveals reallocation of carbon flux from cuticular wax into plastid membrane lipids in a glossy“Newhall”navel orange mutant显示文摘Both cuticle and membrane lipids play essential roles in quality maintenance and disease resistance in fresh fruits.Many reports have indicated the modification of alternative branch pathways in epicuticular wax mutants;however,the specific alterations concerning lipids have not been clarified thus far.Here,we conducted a comprehensive,timeresolved lipidomic,and transcriptomic analysis on the“Newhall”navel orange(WT)and its glossy mutant(MT)“Gannan No.1”.The results revealed severely suppressed wax formation accompanied by significantly elevated production of 36-carbon plastid lipids with increasing fruit maturation in MT.Transcriptomics analysis further identified a series of key functional enzymes and transcription factors putatively involved in the biosynthesis pathways of wax and membrane lipids.Moreover,the high accumulation of jasmonic acid(JA)in MT was possibly due to the need to maintain plastid lipid homeostasis,as the expression levels of two significantly upregulated lipases(CsDAD1 and CsDALL2)were positively correlated with plastid lipids and characterized to hydrolyze plastid lipids to increase the JA content.Our results will provide new insights into the molecular mechanisms underlying the natural variation of plant lipids to lay a foundation for the quality improvement of citrus fruit. | Haoliang Wan Hongbo Liu Jingyu Zhang Yi Lyu Zhuoran Li Yizhong He Xiaoliang Zhang Xiuxin Deng Yariv Brotman Alisdair RFernie Yunjiang Cheng Weiwei Wen | 2020 | Horticulture Research2020，7，1： | 2 |
| 7 | Multiomics-based dissection of citrus flavonoid metabolism using a Citrus reticulata × Poncirus trifoliata population显示文摘Deciphering the genetic basis of plant secondary metabolism will provide useful insights for genetic improvement and enhance our fundamental understanding of plant biological processes.Although citrus plants are among the most important fruit crops worldwide,the genetic basis of secondary metabolism in these plants is largely unknown.Here,we use a high-density linkage map to dissect large-scale flavonoid metabolic traits measured in different tissues(young leaf,old leaf,mature pericarp,and mature pulp)of an F_(1) pseudo-testcross citrus population.We detected 80 flavonoids in this population and identified 138 quantitative trait loci(QTLs)for 57 flavonoids in these four tissues.Based on transcriptional profiling and functional annotation,twenty-one candidate genes were identified,and one gene encoding flavanone 3-hydroxylase(F3H)was functionally verified to result in naturally occurring variation in dihydrokaempferol content through genetic variations in its promoter and coding regions.The abundant data resources collected for diverse citrus germplasms here lay the foundation for complete characterization of the citrus flavonoid biosynthetic pathway and will thereby promote efficient utilization of metabolites in citrus quality improvement. | Jiaolin Mou Zhehui Zhang Haiji Qiu Yang Lu Xiang Zhu Ziquan Fan Qinghua Zhang Junli Ye Alisdair R.Fernie Yunjiang Cheng Xiuxin Deng Weiwei Wen | 2021 | Horticulture Research2021，8，1： | 2 |
| 8 | Genetic diversity and relatedness analysis of nine wild species of tree peony based on simple sequence repeats markers显示文摘Tree peony has nine wild species,but the evolutionary relationship of them is still unclear.Here,a total of 274 specimens from 22 natural populations of nine wild species were collected,and their genetic diversity and similarity was analyzed based on Simple Sequence Repeats(SSR)molecular markers.A total of 106 alleles were generated based on 20 primers and with an average of 5.3 alleles per primer.Shannon’s information index(I)ranged from 0.6333 to 1.7842,and the average of Nei’s genetic diversity coefficient(H)was 0.5771.Polymorphism Information Content(PIC)value varied from 0.29 to 0.77,ten of these primers had high polymorphism(PIC≥0.50).All the above genetic parameters of primers reflect more rich genetic diversity information compared with other researches using SSR molecular markers to study the genetic diversity of tree peony wild species.At the population level,the lowest and highest degree of genetic diversity occurred in Paeonia ludlowii-P1 and P.delavayi-P3 population,respectively.Whereas at species level,the genetic diversity of 9 wild peony species was as follows:P.lutea>P.delavayi>P.rockii>P.qiui>P.ostii>P.decomposita>P.potaninii>P.spontanea>P.ludlowii.Furthermore,cluster analysis at species level divided the nine wild tree peony species into two branches.In branch I,the closest phylogenetic relationship was found between P.ostii and P.rockii,followed by P.spontanea,P.qiui,and P.decomposita.In branch II,the closest relationship occurred between P.lutea and P.delavayi,followed by P.potaninii and P.ludlowii.Clustering results supported the division of tree peonies into two subsects(Delavayanae and Vaginatae),it also supported P.potaninii and P.ludlowii as independent species.The results provided novel insight into the genetic diversity and phylogenetic relationship of nine wild tree peony species.It will help formulate comprehensive protection measures of wild germplasm resources and select proper parents for distant hybridization in the future. | Yuqian Xue Rong Liu Jingqi Xue Shunli Wang Xiuxin Zhang | 2021 | Horticultural Plant Journal2021，7，6： | 1 |
| 9 | Structural variation and parallel evolution of apomixis in citrus during domestication and diversification显示文摘Apomixis,or asexual seed formation,is prevalent in Citrinae via a mechanism termed nucellar or adventitious embryony.Here,multiple embryos of a maternal genotype form directly from nucellar cells in the ovule and can outcompete the developing zygotic embryo as they utilize the sexually derived endosperm for growth.Whilst nucellar embryony enables the propagation of clonal plants of maternal genetic constitution,it is also a barrier to effective breeding through hybridization.To address the genetics and evolution of apomixis in Citrinae,a chromosome-level genome of the Hongkong kumquat(Fortunella hindsii)was assembled following a genome-wide variation map including structural variants(SVs)based on 234 Citrinae accessions.This map revealed that hybrid citrus cultivars shelter genome-wide deleterious mutations and SVs into heterozygous states free from recessive selection,which may explain the capability of nucellar embryony in most cultivars during Citrinae diversification.Analyses revealed that parallel evolution may explain the repeated origin of apomixis in different genera of Citrinae.Within Fortunella,we found that apomixis of some varieties originated via introgression.In apomictic Fortunella,the locus associated with apomixis contains the FhRWP gene,encoding an RWP-RK domain-containing protein previously shown to be required for nucellar embryogenesis in Citrus.We found the heterozygous SV in the FhRWP and CitRWP promoters from apomictic Citrus and Fortunella,due to either two or three miniature inverted transposon element(MITE)insertions.A transcription factor,FhARID,encoding an AT-rich interaction domain-containing protein binds to the MITEs in the promoter of apomictic varieties,which facilitates induction of nucellar embryogenesis.This study provides evolutionary genomic and molecular insights into apomixis in Citrinae and has potential ramifications for citrus breeding. | Nan Wang Xietian Song Junli Ye Siqi Zhang Zhen Cao Chenqiao Zhu Jianbing Hu Yin Zhou Yue Huang Shuo Cao Zhongjie Liu Xiaomeng Wu Lijun Chai Wenwu Guo Qiang Xu Brandon S.Gaut Anna M.G.Koltunow Yongfeng Zhou Xiuxin Deng | 2022 | National Science Review2022，9，10： | 1 |
| 10 | A monolithically sculpted van der Waals nano-opto-electro-mechanical coupler显示文摘The nano-opto-electro-mechanical systems(NOEMS)are a class of hybrid solid devices that hold promises in both classical and quantum manipulations of the interplay between one or more degrees of freedom in optical,electrical and mechanical modes.To date,studies of NOEMS using van der Waals(vdW)heterostructures are very limited,although vdW materials are known for emerging phenomena such as spin,valley,and topological physics.Here,we devise a universal method to easily and robustly fabricate vdW heterostructures into an architecture that hosts opto-electro-mechanical couplings in one single device.We demonstrated several functionalities,including nano-mechanical resonator,vacuum channel diodes,and ultrafast thermo-radiator,using monolithically sculpted graphene NOEMS as a platform.Optical readout of electric and magnetic field tuning of mechanical resonance in a CrOCl/graphene vdW NOEMS is further demonstrated.Our results suggest that the introduction of the vdW heterostructure into the NOEMS family will be of particular potential for the development of novel lab-on-a-chip systems. | Tongyao Zhang Hanwen Wang Xiuxin Xia Ning Yan Xuanzhe Sha Jinqiang Huang Kenji Watanabe Takashi Taniguchi Mengjian Zhu Lei Wang Jiantou Gao Xilong Liang Chengbing Qin Liantuan Xiao Dongming Sun Jing Zhang Zheng Han Xiaoxi Li | 2022 | Light(Science & Applications)2022，11，3： | 1 |

| 12 | Molecular Cloning and Expression Analysis of Cryptochrome Gene Ps CRY2in Tree Peony显示文摘Cryptochromes are blue/ultraviolet-A(UV-A) light receptors involved in regulating various aspects of plant growth and development.Investigations of the structure and functions of cryptochromes in plants have largely focused on herbaceous plants. However, few data on the function of CRY2 are available in woody plants. In this study, a cryptochrome 2(CRY2) gene was isolated from Paeonia suffruticosa by Reverse Transcription Polymerase Chain Reaction(RT-PCR). Sequence alignment and motif analysis showed that the deduced amino acids contained a PHR domain near the amino terminus and a CCT domain near the carboxy terminus. Ps CRY2 showed high identity with At CRY2 of Arabidopsis.Phylogenetic analysis indicated that it was closely related to Citrus sinensis. Gene expression analysis revealed that the highest expression levels of Ps CRY2 occurred in the bud and seed embryo of P. suffruticosa, followed by the roots, stems, and leaves. Ps CRY2 was upregulated during the entire process of bud differentiation, whereas this was downregulated during the early stage of bud development and upregulated in the middle and late stages. The highest level of Ps CRY2 expression was observed in the big bell-like flower buds. These results suggested that Ps CRY2 plays an important role in both bud differentiation and bud development. The expression patterns of Ps CRY2 in the buds of ‘Luoyanghong' and ‘Qiufa1' were similar, whereas that in the buds of ‘Qiufa 1' was significantly higher than in the buds of ‘Luoyanghong'. The buds of plants subjected to different photoperiod treatments exhibited variations in Ps CRY2 expression patterns. The expression of Ps CRY2 decreased during bud sprouting and in the small bell-like flower buds that were subjected to short-day photoperiod compared to that observed under long-day photoperiod. | REN Xiuxia WANG Shunli XUE Jingqi ZHU Fuyong LIU Chuanjiao ZHANG Xiuxin | 2016 | Horticultural Plant Journal2016，2，6： | 1 |
| 13 | QTL analysis reveals reduction of fruit water loss by NAC042 through regulation of cuticular wax synthesis in citrus fruit显示文摘Postharvest water loss is a critical factor that determines the quality and shelf life of fresh fruit.Cuticular wax constitutes a key barrier to reduce fruit water loss.Our previous study has shown that HJ(Citrus reticulata)has a significantly higher postharvest water loss rate than ZK(Poncirus trifoliata).Here,we investigated the fruit water loss rate of the HJ×ZK F1pseudo-testcross population in 2016 and 2019.QTL mapping for fruit water loss rate was performed by high-density genetic map and bulk segregant analysis,and QTL9 was identified to be associated with fruit water loss.The expression of NAC042 from QTL9 in ZK was 170-fold that in HJ.Heterologous expression in Arabidopsis showed that NAC042could reduce the water loss of leaves by increasing the cuticular wax content(especially alkanes).Further expression analysis revealed that NAC042 could enhance the expression of many wax-related genes in Arabidopsis leaves,including AtKCS1,AtKCS2,AtKCS9,AtKCS20,At CER1 and At CER3.Therefore,NAC042 might be involved in fruit cuticular wax synthesis to reduce fruit water loss.The findings provide new insights into the regulation of cuticular wax and fruit water loss as well as valuable information for breeding of citrus with better storability. | Hongbin Yang Zhifeng Zhu Mingfei Zhang Xin Li Rangwei Xu Feng Zhu Juan Xu Xiuxin Deng Yunjiang Cheng | 2022 | Horticultural Plant Journal2022，8，6： | 1 |

| 15 | Citrus β-carotene hydroxylase 2 (BCH2) participates in xanthophyll synthesis by catalyzing the hydroxylation of β-carotene and compensates for BCH1 in citrus carotenoid metabolism显示文摘Abstract As an essential horticultural crop,Citrus has carotenoid diversity,which affects its aesthetic and nutritional values.β,β-Xanthophylls are the primary carotenoids accumulated in citrus fruits,and non-heme di-iron carotene hydroxylase(BCH)enzymes are mainly responsible forβ,β-xanthophyll synthesis.Previous studies have focused on the hydroxylation of BCH1,but the role of its paralogous gene in citrus,BCH2,remains largely unknown.In this study,we revealed theβ-hydroxylation activity of citrus BCH2(CsBCH2)for the first time through the functional complementation assay using Escherichia coli,although CsBCH2 exhibited a lower activity in hydroxylatingβ-carotene intoβ-cryptoxanthin than citrus BCH1(CsBCH1).Our results showed that overexpression of CsBCH2 in citrus callus increased xanthophyll proportion and plastoglobule size with feedback regulation of carotenogenic gene expression.This study revealed the distinct expression patterns and functional characteristics of two paralogous genes,CsBCH1 and CsBCH2,and illustrated the backup compensatory role of CsBCH2 for CsBCH1 in citrus xanthophyll biosynthesis.The independent function of CsBCH2 and its cooperative function with CsBCH1 inβ-cryptoxanthin biosynthesis suggested the potential of CsBCH2 to be employed for expanding the synthetic biology toolkit in carotenoid engineering。 | Yingzi Zhang Jiajing Jin Shenchao Zhu Quan Sun Yin Zhang Zongzhou Xie Junli Ye Xiuxin Deng | 2023 | Horticulture Research2023，10，3： | 0 |
| 16 | NEW INSIGHTS INTO THE PHYLOGENY AND SPECIATION OF KUMQUAT (FORTUNELLA SPP.) BASED ON CHLOROPLAST SNP, NUCLEAR SSR AND WHOLE-GENOME SEQUENCING显示文摘Kumquat(Fortunella spp.)is a fruit and ornamental crop worldwide due to the palatable taste and high ornamental value of its fruit.Although Fortunella is classified into the economically important true citrus fruit tree group together with Citrus and Poncirus,few studies have been focused on its evolutionary scenario.In this study,analysis of five chloroplast loci and 47 nuclear microsatellites(nSSR)loci from 38 kumquat and 10 citrus accessions revealed the independent phylogeny of Fortunella among citrus taxa,and that Fortunella mainly comprises two populations:CUL,cultivated Fortunella spp.(F.margarita,F.crassifolia and F.japonica);and HK,wild Hong Kong kumquat(Fortunella hindsii).Genomic analysis based on whole-genome SNPs indicated that the allele frequency of both pupations deviated from the neutral selection model,suggesting directional selection was a force driving their evolutions.CUL exhibited lower genomic diversity and higher linkage strength than HK,suggesting artificial selection involved in its origin.A high level of genetic differentiation(Fst=0.364)was detected and obviously asynchronous demographic changes were observed between CUL and HK.Based on these results,a new hypothesis for the speciation of Fortunella is proposed. | Chenqiao ZHU Peng CHEN Junli YE Hang LI Yue HUANG Xiaoming YANG Chuanwu CHEN Chenglei ZHANG Yuantao XU Xiaoli WANG Xiang YAN Guangzhou DENG Xiaolin JIANG Nan WANG Hongxing WANG Quan SUN Yun LIU Di FENG Min YU Xietian SONG Zongzhou XIE Yunliu ZENG Lijun CHAI Qiang XU Chongling DENG Yunjiang CHENG Xiuxin DENG | 2022 | Frontiers of Agricultural Science and Engineering2022，9，4： | 0 |

| 18 | Design and experiment of high-productivity two-stage vacuum pressure swing adsorption process for carbon capturing from dry flue gas显示文摘A two-stage vacuum pressure swing adsorption(VPSA)process that coupled kinetically controlled and equilibrium controlled separation process with reflux has been investigated for capturing carbon dioxide from dry flue gas(85%N_(2)/15%CO_(2)).In the first enriching stage,carbon molecular sieve(CMS),which shows kinetic selectivity for CO_(2)/N_(2),is adopted as the adsorbent to remove most N_(2)in feed gas,thereby upgrading CO_(2)and significantly reducing the amount for further refinement.The second stage loads zeolite 13X as adsorbent to purify the CO_(2)-rich flow from the first stage for meeting the requirements of National Energy Technology Laboratory.Series of experiments have been conducted for adsorption isotherms measuring and lab-scale experimental validation as well as analysis.The effect of feed composition on the separation performance of the PSA system was studied experimentally and theoretically here.The optimal results achieved 95.1%purity and 92.9%recovery with a high CO_(2)productivity(1.89 mol CO_(2)·h^(-1)·kg^(-1))and an appropriate energy consumption of 1.07 MJ·(kg CO_(2))^(-1).Further analysis has been carried out by simulation for explicating the temperature,pressure,and concentration distribution at cyclic steady state. | Xiuxin Yu Bing Liu Yuanhui Shen Donghui Zhang | 2022 | Chinese Journal of Chemical Engineering2022，35，3： | 0 |
| 19 | Establishment of highly efficient plant regeneration of Paeonia ostii‘Fengdan’through optimization of callus,adventitious shoot,and rooting induction显示文摘Tree peony is a famous ornamental plant,while the low propagation rate is the main hurdles hindering the industry development.Till now,the highly efficient regeneration system for tree peony is not established.In this study,using Paeonia ostii’Fengdan’mature embryos,the effects of variations in inoculation method,initiating culture,adventitious shoot induction,rooting media,plant growth regulators(PGRs),and a nonconventional PGR(plant extracts)on regeneration from explants were evaluated.In embryo cultures,embryonic callus induction rate of 1/4 embryos was the highest among those of embryos with other three technical treatments(whole embryos,1/2 embryos,and pieces of embryos).The woody plant medium(WPM)containing 1.0 mg·L^(-1)6-BA,0.5 mg·L^(-1)GA3,30.0 g·L^(-1)sucrose,and 3.0 g·L^(-1)phytagel significantly improved shoot induction and multiplication.3.0 mg·L^(-1)plant extracts promoted hypocotyl germination,rooting,and root growth,in direct embryo culture,and a combination of 3.0 mg·L^(-1)plant extracts+2.0 mg·L^(-1)IBA+1.5 mg·L^(-1)IAA produced optimal rooting induction rate for multiple shoots in direct embryo culture and indirect somatic embryogenesis.For the three in vitro micropropagation methods,the highest shoot proliferation coefficient(5.4±0.2)was obtained with indirect somatic embryogenesis.Fortunately,the propagation ability of shoots remains high,even when culture propagation was continued for more than two years.Thus,a reliable system for plant regeneration from mature embryos derived from P.ostii’Fengdan’callus and two direct embryo culture systems have been established.The novel regeneration system could facilitate uniform seedling production. | Rong Liu Yuqian Xue Huiting Ci Jie Gao Shunli Wang Xiuxin Zhang | 2022 | Horticultural Plant Journal2022，8，6： | 0 |
