| 1 | Rice CYP703A3, a cytochrome P450 hydroxylase, is essential for development of anther cuticle and pollen exine显示文摘Anther cuticle and pollen exine act as protective envelopes for the male gametophyte or pollen grain, but the mechanism underlying the synthesis of these lipidic polymers remains unclear. Previously, a tapetum‐expressed CYP703A3, a putative cytochrome P450 fatty acid hydroxylase, was shown to be essential for male fertility in rice(Oryza sativa L.). However,the biochemical and biological roles of CYP703A3 has not been characterized. Here, we observed that cyp703a3‐2 caused by one base insertion in CYP703A3 displays defective pollen exine and anther epicuticular layer, which differs from Arabidopsis cyp703a2 in which only defective pollen exine occurs. Consistently, chemical composition assay showed that levels of cutin monomers and wax components were dramatically reduced in cyp703a3‐2 anthers. Unlike the wide range of substrates of Arabidopsis CYP703A2, CYP703A3 functions as an in‐chain hydroxylase only for a specific substrate, lauric acid, preferably generating 7‐hydroxylated lauric acid. Moreover, chromatin immunoprecipitation and expression analyses revealed that the expression of CYP703A3 is directly regulated by Tapetum Degeneration Retardation, a known regulator of tapetum PCD and pollen exine formation. Collectively, our results suggest that CYP703A3 represents a conserved and diversified biochemical pathway for in‐chain hydroxylation of lauric acid required for the development of male organ in higher plants. | Xijia Yang Di Wu Jianxin Shi Yi He Franck Pinot Bernard Grausem Changsong Yin Lu Zhu Mingjiao Chen Zhijing Luo Wanqi Liang Dabing Zhang | 2014 | Journal of Integrative Plant Biology2014，56，10： | 21 |
| 2 | Comprehensive analysis of NAC transcription factors in diploid Gossypium: sequence conservation and expression analysis uncover their roles during fiber development显示文摘Determining how function evolves following gene duplication is necessary for understanding gene expansion.Transcription factors(TFs)are a class of proteins that regulate gene expression by binding to specific cis-acting elements in the promoters of target genes,subsequently activating or repressing their transcription.In the present study,we systematically examined the functional diversification of the NAC transcription factor(NAC-TFs)family by analyzing their chromosomal location,structure,phylogeny,and expression pattern in Gossypium raimondii(Gr)and G.arboreum(Ga).The 145 and 141 NAC genes identified in the Gr and Ga genomes,respectively,were annotated and divided into 18 subfamilies,which showed distinct divergence in gene structure and expression patterns during fiber development.In addition,when the functional parameters were examined,clear divergence was observed within tandem clusters,which suggested that subfunctionalization had occurred among duplicate genes.The expression patterns of homologous gene pairs also changed,suggestive of the diversification of gene function during the evolution of diploid cotton.These findings provide insights into the mechanisms underlying the functional differentiation of duplicated NAC-TFs genes in two diploid cotton species. | Haihong Shang Zhongna Wang Changsong Zou Zhen Zhang Weijie Li Junwen Li Yuzhen Shi Wankui Gong Tingting Chen Aiying Liu Juwu Gong Qun Ge Youlu Yuan | 2016 | Science China(Life Sciences)2016，59，2： | 12 |

| 4 | Structural evolution of layered oxide cathodes for spent Li-ion batteries:Degradation mechanism and repair strategy显示文摘Sustainable development has long been recognized as one of the most critical issues in today’s energy and environment-conscious society.It has never been more urgent to recycle and reuse the end-of-life cathode materials.Here,this work systematically investigates the structure-critical degradation mechanism of polycrystalline LiNi_(x)Co_(y)Mn_(1−x−y)O_(2)(NCM),combining experimental characterization and DFT simulations.Targeting the key degradation factors,a synergistic repair strategy based on deep mechanochemical activation and heat treatment was successfully proposed to direct regenerate the degradedNCMmaterial.Studies indicate the induction and promotion of synergistic repair technique on the reconstruction of particlemorphology,the recovery of the chemical composition and crystal structure,and the favorable transformation of the impurities phase in the failed materials.In particular,the synergistic repair process induces a gradient distribution of LiF and further enables partial fluorine doping into the NCM surface,forming abundant oxygen vacancies and increasing the content of highly reactive Ni2+.Benefiting from the comprehensive treatment for the multi-scale and multi-form degradation behaviors,the repaired material exhibits a capacity of 176.8 mA h g^(-1)at 0.1 C,which is comparable to the corresponding commercial material(172.8 mA h g^(-1)).The satisfactory capacity of the recovered cathode proves that it is an effective direct renovating strategy. | Shan Jin Jianquan Liang Deying Mu Tianning Lin Yuyang Tian Jian Zhang YueWang Meng Chen Qingmo Shi Changsong Dai | 2023 | SusMat2023，3，3： | 1 |
| 5 | Below-knee amputation of the left hindleg of a giant panda显示文摘The giant panda is an icon for conservation worldwide and in China it is strictly protected by law.With continuing protection of their environment,the number and size of family groups of all wild animals in China have been increasing each year,with a consequent increase in fighting for food and territory.Wild giant pandas that have been attacked by other animals,such as black bears or boars,are often found in the Wolong and Baoxing Conservation Centers for the Giant Panda(CCGP). | Guangneng Peng Zhijun Zhong Changsong Liu Junliang Deng Guangyou Yang Yuhui Baichun Qing Jinjiang Shi Dong Zhou Zhijin Zhou | 2012 | 畜牧与兽医2012，44，S2： | 0 |
| 6 | Post-modification of MOF to fabricate single-atom dispersed hollow nanocages catalysts for enhancing CO_(2)conversion显示文摘During the catalytic process,the microenvironment and surface area of the catalyst will affect the catalytic performance.Hence,an assisted organic linker coated metal-organic framework(MOF)has been applied,to form Ni/HNC(HNC represents hollow nanocage)for electrocatalytic CO_(2)reduction.Remarkably,Ni/HNC achieves superb activity with high Faradaic efficiency(FE)of 97.2%at 0.7 V vs.reversible hydrogen electrode(RHE)towards CO_(2)conversion to CO.In contrast to Ni/NPC(afforded from the naked MOF),the Ni/HNC displays higher FE and selectivity on CO rather than H_(2),owing to the large nanocage which extraordinarily facilitates CO_(2)enrichment and the active sites easily accessible.This work provides a general and feasible route to construct high-efficient electrochemical CO_(2)reduction reaction(EC-CO_(2)RR)catalysts via post-modified MOFs. | Ruirui Yun Ruiming Xu Changsong Shi Beibei Zhang Tuanhui Li Lei He Tian Sheng Zheng Chen | 2023 | Nano Research2023，16，7： | 0 |
