| 1 | Developing gene-tagged molecular markers for evaluation of genetic association of apple SWEET genes with fruit sugar accumulation显示文摘Sugar content is an important component of fruit quality.Although sugar transporters are known to be crucial for sugar accumulation,the role of genes encoding SWEET sugar transporters in fruit sugar accumulation remains elusive.Here we report the effect of the SWEET genes on fruit sugar accumulation in apple.A total of 25 MdSWEET genes were identified in the apple genome,and 9 were highly expressed throughout fruit development.Molecular markers of these 9 MdSWEET genes were developed and used for genotyping of 188 apple cultivars.The association of polymorphic MdSWEET genes with soluble sugar content in mature fruit was analyzed.Three genes,MdSWEET2e,MdSWEET9b,and MdSWEET15a,were significantly associated with fruit sugar content,with MdSWEET15a and MdSWEET9b accounting for a relatively large proportion of phenotypic variation in sugar content.Moreover,both MdSWEET9b and MdSWEET15a are located on chromosomal regions harboring QTLs for sugar content.Hence,MdSWEET9b and MdSWEET15a are likely candidates regulating fruit sugar accumulation in apple.Our study not only presents an efficient way of implementing gene functional study but also provides molecular tools for genetic improvement of fruit quality in apple-breeding programs. | Qiaoling Zhen Ting Fang Qian Peng Liao Liao Li Zhao Albert Owiti Yuepeng Han | 2018 | Horticulture Research2018，5，1： | 12 |
| 2 | Investigation of benzylisoquinoline alkaloid biosynthetic pathway and its transcriptional regulation in lotus显示文摘Lotus predominantly accumulates benzylisoquinoline alkaloids(BIAs),but their biosynthesis and regulation remain unclear.Here,we investigated structural and regulatory genes involved in BIA accumulation in lotus.Two clustered CYP80 genes were identified to be responsible for the biosynthesis of bis-BIAs and aporphine-type BIAs,respectively,and their tissue-specific expression causes divergence in alkaloid component between leaf and embryo.In contrast with the common(S)-reticuline precursor for most BIAs,aporphine alkaloids in lotus leaf may result from the(S)-N-methylcoclaurine precursor.Structural diversity of BIA alkaloids in the leaf is attributed to enzymatic modifications,including intramolecular C–C phenol coupling on ring A and methylation and demethylation at certain positions.Additionally,most BIA biosynthetic pathway genes show higher levels of expression in the leaf of high-BIA cultivar compared with low-BIA cultivar,suggesting transcriptional regulation of BIA accumulation in lotus.Five transcription factors,including three MYBs,one ethylene-responsive factor,and one basic helix–loop–helix(bHLH),were identified to be candidate regulators of BIA biosynthesis in lotus.Our study reveals a BIA biosynthetic pathway and its transcriptional regulation in lotus,which will enable a deeper understanding of BIA biosynthesis in plants. | Xianbao Deng Li Zhao Ting Fang Yaqian Xiong Collins Ogutu Dong Yang Sornkanok Vimolmangkang Yanling Liu Yuepeng Han | 2018 | Horticulture Research2018，5，1： | 8 |
| 3 | Copper base materials prepared by gel-casting process显示文摘Gel-casting process was developed as a new molding process in the field of copper base powder metallurgy to manufacture metal parts with excellent performance and complex shapes.Through changing the parameters of gel-casting process,such as dispersant and solid loading,the corresponding effects on the rheology of Cu slurries,molding and sintering behaviors were studied.The results show that the viscosity of Cu slurries was significantly reduced with an increase in dispersant.The most appropriate solid loading was found to be 61% and the sintering temperature was 910°C in these experiments.After the optimization of parameters of gel-casting process,copper composite parts with relatively high density and better properties were obtained. | LIU Weihua JIA Chengchang SHI Yantao HAN Yuepeng | 2008 | Rare Metals2008，27，1： | 7 |
| 4 | Reduced representation genome sequencing reveals patterns of genetic diversity and selection in apple显示文摘Identifying DNA sequence variations is a fundamental step towards deciphering the genetic basis of traits of interest.Here,a total of 20 cultivated and 10 wild apples were genotyped using specific-locus amplified fragment sequencing,and 39,635 single nucleotide polymorphisms with no missing genotypes and evenly distributed along the genome were selected to investigate patterns of genome-wide genetic variations between cultivated and wild apples.Overall,wild apples displayed higher levels of genetic diversity than cultivated apples.Linkage disequilibrium(LD) decays were observed quite rapidly in cultivated and wild apples,with an r^2-value below 0.2 at 440 and 280 bp,respectively.Moreover,bidirectional gene flow and different distribution patterns of LD blocks were detected between domesticated and wild apples.Most LD blocks unique to cultivated apples were located within QTL regions controlling fruit quality,thus suggesting that fruit quality had probably undergone selection during apple domestication.The genome of the earliest cultivated apple in China,Nai,was highly similar to that of Malus sieversii,and contained a small portion of genetic material from other wild apple species.This suggested that introgression could have been an important driving force during initial domestication of apple.These findings will facilitate future breeding and genetic dissection of complex traits in apple. | Baiquan Ma Liao Liao Qian Peng Ting Fang Hui Zhou Schuyler S.

| 5 | Unraveling a genetic roadmap for improved taste in the domesticated apple显示文摘Although taste is an important aspect of fruit quality, an understanding of its genetic control remains elusive in apple and other fruit crops. In this study, we conducted genomic sequence analysis of 497 Malus accessions and revealed erosion of genetic diversity caused by apple breeding and possible independent domestication events of dessert and cider apples. Signatures of selection for fruit acidity and size, but not for fruit sugar content, were detected during the processes of both domestication and improvement. Furthermore, we found that single mutations in major genes affecting fruit taste, including Ma1, MdTDT, and MdSOT2, dramatically decrease malate, citrate, and sorbitol accumulation, respectively, and correspond to important domestication events. Interestingly, Ma1 was identified to have pleiotropic effects on both organic acid content and sugar:acid ratio, suggesting that it plays a vital role in determining fruit taste. Fruit taste is unlikely to have been negatively affected by linkage drag associated with selection for larger fruit that resulted from the pyramiding of multiple genes with minor effects on fruit size. Collectively, our study provides new insights into the genetic basis of fruit quality and its evolutionary roadmap during apple domestication, pinpointing several candidate genes for genetic manipulation of fruit taste in apple. | Liao Liao Weihan Zhang Bo Zhang Ting Fang Xiao-Fei Wang Yarning Cai Collins Ogutu Lei Gao Gang Chen Xiaoqing Nie Jinsheng Xu Quanyan Zhang Yiran Ren Jianqiang Yu Chukun Wang Cecilia H.Deng Baiquan Ma Beibei Zheng Chun-Xiang You Da-Gang Hu Richard Espley Kui Lin-Wang Jia-Long Yao Andrew C.Allan Awais Khan Schuyler S.Korban Zhangjun Fei Ray Ming Yu-Jin Hao Li Li Yuepeng Han | 2021 | Molecular Plant2021，14，9： | 5 |
| 6 | Generation of transgenic wheat resistant to wheat yellow mosaic virus and identification of gene silence induced by virus infection显示文摘The plasmid containing the promoter Actl, the coat protein (cp) gene of wheat yellow mosaic virus (WYMV) and the selectable bar gene, was delivered via particle bombardment, directly into immature embryos of a wheat culti-vars. PCR and PCR-RFLP were employed to screen the existence of the cp gene in T0 and T1 generations. Seeds from the positive T1 plants were sowed in fields heavily contaminated with WYMV to detect their resistance. In field trial of virus infection, one of the transgenic wheat lines, P8-T2, exhibited highly disease-resistance. Western blot and RT-PCR analysis showed that the expression level of cp gene in the resistant transgenic line was reduced greatly compared to those susceptible to WYMV infection. This provided evidence to presume that the resistance obtained by the transgenic wheat line was stimulated by the mechanism of the virus induced gene silencing. | DONG Jin HE Zhentian HAN Chenggui CHEN Xiulan ZHANG Lingdi LIU Weihua HAN Yuepeng WANG Jinrong ZHAI Yafeng YU Jialin LIU Yi XIAO Yueyan | 2002 | Chinese Science Bulletin2002，47，17： | 2 |

| 12 | The E3 ubiquitin ligase SINA1 and the protein kinase BIN2 cooperatively regulate PHR1 in apple anthocyanin biosynthesis显示文摘PHR1(PHOSPHATE STARVATION RESPONSE1)plays key roles in the inorganic phosphate(Pi)starvation response and in Pi deficiency-induced anthocyanin biosynthesis in plants. However, the post-translational regulation of PHR1 is unclear,and the molecular basis of PHR1-mediated anthocyanin biosynthesis remains elusive. In this study, we determined that MdPHR1 was essential for Pi deficiency-induced anthocyanin accumulation in apple(Malus × domestica). MdPHR1 interacted with MdWRKY75, a positive regulator of anthocyanin biosynthesis, to enhance the MdWRKY75-activated transcription of MdMYB1,leading to anthocyanin accumulation. In addition,the E3 ubiquitin ligase SEVEN IN ABSENTIA1(MdSINA1) negatively regulated MdPHR1-promoted anthocyanin biosynthesis via the ubiquitination-mediated degradation of MdPHR1.Moreover, the protein kinase apple BRASSINOSTEROID INSENSITIVE2(MdBIN2) phosphorylated MdPHR1 and positively regulated MdPHR1-mediated anthocyanin accumulation by attenuating the MdSINA1-mediated ubiquitination degradation of MdPHR1. Taken together,these findings not only demonstrate the regulatory role of MdPHR1 in Pi starvation induced anthocyanin accumulation, but also provide an insight into the post-translational regulation of PHR1. | Jian‐Ping An Hong‐Liang Li Zhi‐Ying Liu Da‐Ru Wang Chun‐Xiang You Yuepeng Han | 2023 | Journal of Integrative Plant Biology2023，65，9： | 0 |
| 13 | A study of the soil water potential threshold values to trigger irrigation of ‘Shimizu Hakuto’ peach at pivotal fruit developmental stages显示文摘Water management is an important practice that affects fruit size and quality.Effective implementation of irrigation scheduling requires knowledge of the appropriate indicators and thresholds,which are established manly based on the effects of water deficits on final fruit quality.Few studies have focused on the real-time effects of water status on fruit and shoot growth.To establish soil water potential (ψ_(soil)) thresholds to trigger irrigation of peach at pivotal fruit developmental stages,photogrammetry,^(13)C labelling,and other techniques were used in this study to investigate real-time changes in stem diameter,fruit projected area,net leaf photosynthetic rate (P_(n)),and allocation of photoassimilates to fruit under soil water potential conditions ranging from saturation to stress in 6-year-old Shimizu hakuto’peach.Stem growth,fruit growth,and P_n exhibited gradually decreasing sensitivity to water deficits during fruit developmental stages I,II,and III.Stem diameter growth was significantly inhibited whenψ_(soil)dropped to-8.5,-7.6,and-5.4 k Pa,respectively.Fruit growth rate was low,reaching zero when theψ_(soil)was-9.0 to-23.1,-14.9 to-21.4,and-16.5 to-23.3 k Pa,respectively,and P_ndecreased significantly when theψ_(soil)reached-24.2,-22.7,and-20.4 kPa,respectively.In addition,more photoassimilates were allocated to fruit under moderateψ_(soil)conditions (-10.1 to-17.0 k Pa) than under otherψ_(soil)values.Our results revealed threeψ_(soil)thresholds,-10.0,-15.0,and-15.0 kPa,suitable for triggering irrigation during stages I,II,and III,respectively.These thresholds can be helpful for controlling excessive tree vigor,maintaining rapid fruit growth and leaf photosynthesis,and promoting the allocation of more photoassimilates to fruit. | Yusui Lou Yuepeng Han Yubin Miao Hongquan Shang Zhongwei Lv Lei Wang Shiping Wang | 2024 | Horticultural Plant Journal2024，10，2： | 0 |
| 14 | Temporally Separated CO_(2) Photoreduction and H_(2)O Photooxidation over Redox-Active Conjugated Organic Polymer Films显示文摘Photocatalytic CO_(2) reduction with H_(2)O of chemicals without H2 generation is interesting but challenging.Herein,we report temporally separated CO_(2) photoreduction and H_(2)O photooxidation that are achieved over redox-active o-hydroxyazo-based conjugated organic polymer films(HAzo-COPFs),affording CO with high efficiency as the sole reduction product.HAzo-COPFs are prepared via interfacial diazo-coupling reactions of aromatic diamines and diphenols,and HAzo-COPF-1 from 4,4′-biphenol and benzidine shows the best performance with a CO generation rate of 53.6μmol g−1 h−1 under visible-light irradiation(>420 nm).Interestingly,we discovered that diphenol(DP-OH)moieties in HAzo-COPFs,serving as electron and proton donors to participate in CO_(2) photoreduction,are oxidized into quinone(DP=O)moieties,which are subsequently photoreduced to regenerate DP-OH in H_(2)O photooxidation.Consequently,CO_(2) photoreduction and H_(2)O photooxidation are temporally separated and perfectly coupled via redox transformation between DP-OH and DP=O that form in situ,affording enhanced charge carrier separation and inhibiting the hydrogen evolution reaction.This work provides new insights for the design of COP photocatalysts and artificial photosynthesis. | Guipeng Ji Yuepeng Wang Wenqiang Ye Meifang Chen Fengtao Zhang Yanfei Zhao Shengrui Tong Buxing Han Zhimin Liu | 2023 | CCS Chemistry2023，5，8： | 0 |
| 15 | MdbHLH162 connects the gibberellin and jasmonic acid signals to regulate anthocyanin biosynthesis in apple显示文摘Anthocyanins are secondary metabolites induced by environmental stimuli and developmental signals.The positive regulators of anthocyanin biosynthesis have been reported,whereas the anthocyanin repressors have been neglected.Although the signal transduction pathways of gibberellin(GA)and jasmonic acid(JA)and their regulation of anthocyanin biosynthesis have been investigated,the cross-talk between GA and JA and the antagonistic mechanism of regulating anthocyanin biosynthesis remain to be investigated.In this study,we identified the anthocyanin repressor MdbHLH162 in apple and revealed its molecular mechanism of regulating anthocyanin biosynthesis by integrating the GA and JA signals.MdbHLH162 exerted passive repression by interacting with MdbHLH3 and MdbHLH33,which are two recognized positive regulators of anthocyanin biosynthesis.MdbHLH162 negatively regulated anthocyanin biosynthesis by disrupting the formation of the anthocyanin-activated MdMYB1-MdbHLH3/33complexes and weakening transcriptional activation of the anthocyanin biosynthetic genes MdDFR and MdUF3GT by MdbHLH3 and MdbHLH33.The GA repressor MdRGL2a antagonized MdbHLH162-mediated inhibition of anthocyanins by sequestering MdbHLH162 from the MdbHLH162-MdbHLH3/33 complex.The JA repressors MdJAZ1 and MdJAZ2 interfered with the antagonistic regulation of MdbHLH162 by MdRGL2a by titrating the formation of the MdRGL2a-MdbHLH162 complex.Our findings reveal that MdbHLH162 integrates the GA and JA signals to negatively regulate anthocyanin biosynthesis.This study provides new information for discovering more anthocyanin biosynthesis repressors and explores the cross-talk between hormone signals. | Jian-Ping An Rui-Rui Xu Xiao-Na Wang Xiao-Wei Zhang Chun-Xiang You Yuepeng Han | 2024 | Journal of Integrative Plant Biology2024，66，2： | 0 |
| 16 | PpARF6 acts as an integrator of auxin and ethylene signaling to promote fruit ripening in peach显示文摘Although auxin is known to induce ethylene biosynthesis in some Rosaceae fruit crops,the mechanisms underlying the auxin–ethylene interaction during fruit ripening remain largely unknown.Here,the regulatory role of an auxin response factor,PpARF6,in fruit ripening was investigated in peach.Peach fruits showed accelerated ripening after treatment with auxin and PpARF6 was found to be significantly induced.PpARF6 not only could induce ethylene synthesis by directly activating the transcription of ethylene biosynthetic genes,but also competed with EIN3-binding F-box proteins PpEBF1/2 for binding to ethylene-insensitive3-like proteins PpEIL2/3,thereby keeping PpEIL2/3 active.Moreover,PpARF6 showed an interaction with PpEIL2/3 to enhance the PpEIL2/3-activated transcription of ethylene biosynthetic genes.Additionally,ectopic overexpression of PpARF6 in tomato accelerated fruit ripening by promoting the expression of genes involved in ethylene synthesis and fruit texture.In summary,our results revealed a positive regulatory role of PpARF6 in peach fruit ripening via integrating auxin and ethylene signaling. | Xiaomei Chen Yudi Liu Xian Zhang Beibei Zheng Yuepeng Han Ruo-Xi Zhang | 2023 | Horticulture Research2023，10，9： | 0 |

| 19 | Design of Shield for Non-destructive Testing Accelerator显示文摘The electron linear accelerator used in the non-destructive testing accelerator mainly produces ionizing radiation,and the protection against X-ray is the key point.Based on the different kinds of rays,the effect of the shielding material is different.For X-ray,it is known that the action of high-energy photon flux and matter mainly produces three effects of photoelectric effect,Compton scattering and free electron pairing.The photoelectric effect generation probability is inversely proportional to the fourth order power of the shielding material atomic number;the Compton scattering effect is inversely proportional to the atomic number of the shielding material,and the electron pair generation is inversely proportional to the square of the atomic number of the shielding material.In summary,for shield X-ray,you should choose an element with a high atomic number. | LYU Yuepeng HAN Guangwen ZENG Ziqiang | 2018 | 中国原子能科学研究院年报2018，，1： | 0 |
