| 1 | Characterization and fine mapping of an early senescence mutant (es-t) in Oryza sativa L.显示文摘An es-t (early senescence-temporary) mutant, produced by ethylene methylsulfonate treatment of strain Nipponbare, was identified in rice. The leaves of es-t appeared yellow at the seedling stage, and had decreased chlorophyll content. Rust spots were found during growth in es-t, especially at the leaf margin and tip. The plants showed a typical early-senescence phenotype at the milky stage. The leaf surface of es-t appeared smoother than wild-type leaves under a scanning electron microscope, because the leaves lack siliceous protuberances around the stoma. Chloroplasts grow abnormally and are filled with many starch grains in es-t. Paraffin section analysis showed that the development of the sclerenchyma cells and vascular bundles were also abnormal in es-t. Genetic analysis indicated that es-t was controlled by a recessive gene, which was finely mapped to a 42-kb interval on chromosome 5. These results will facilitate the positional cloning and functional studies of the gene. | YANG YaoLong RAO YuChun LIU HuiJuan FANG YunXia DONG GuoJun HUANG LiChao LENG YuJia GUO LonBiao ZHANG GuangHeng HU Jiang GAO ZhenYu QIAN Qian ZENG DaLi | 2011 | Chinese Science Bulletin2011，56，23： | 8 |
| 2 | Integrated System of Solar Cells with Hierarchical NiCo2O4 Battery-Supercapacitor Hybrid Devices for Self-Driving Light-Emitting Diodes显示文摘An integrated system has been provided with a-Si/H solar cells as energy conversion device,NiCo2O4 battery-supercapacitor hybrid(BSH)as energy storage device,and light emitting diodes(LEDs)as energy utilization device.By designing three-dimensional hierarchical NiCo2O4 arrays as faradic electrode,with capacitive electrode of active carbon(AC),BSHs were assembled with energy density of 16.6 Wh kg-1,power density of 7285 W kg-1,long-term stability with 100% retention after 15,000 cycles,and rather low self-discharge.The NiCo2O4//AC BSH was charged to 1.6 V in 1 s by solar cells and acted as reliable sources for powering LEDs.The integrated system is rational for operation,having an overall efficiency of 8.1% with storage efficiency of 74.24%.The integrated system demonstrates a stable solar power conversion,outstanding energy storage behavior,and reliable light emitting.Our study offers a precious strategy to design a self-driven integrated system for highly efficient energy utilization. | Yuliang Yuan Yangdan Lu BeiEr Jia Haichao Tang Lingxiang Chen YuJia Zeng Yang Hou Qinghua Zhang Qinggang He Lei Jiao Jianxing Leng Zhizhen Ye Jianguo Lu | 2019 | Nano-Micro Letters2019，11，3： | 5 |
| 3 | The pleiotropic ABNORMAL FLOWER AND DWARF1 affects plant height, floral development and grain yield in rice显示文摘Moderate plant height and successful establishment of reproductive organs play pivotal roles in rice grain production. The molecular mechanism that controls the two aspects remains unclear in rice. In the present study,we characterized a rice gene, ABNORMAL FLOWER AND DWARF1(AFD1) that determined plant height, floral development and grain yield. The afd1 mutant showed variable defects including the dwarfism, long panicle, low seed setting and reduced grain yield. In addition, abnormal floral organs were also observed in the afd1 mutant including slender and thick hulls, and hull-like lodicules.AFD1 encoded a DUF640 domain protein and was expressed in all tested tissues and organs. Subcellular localization showed AFD1-green fluorescent fusion protein(GFP) was localized in the nucleus. Meantime, our results suggested that AFD1 regulated the expression of cell division and expansion related genes. | Deyong Ren Yuchun Rao Liwen Wu Qiankun Xu Zizhuang Li Haiping Yu Yu Zhang Yujia Leng Jiang Hu Li Zhu Zhenyu Gao Guojun Dong Guangheng Zhang Longbiao Guo Dali Zeng Qian Qian | 2016 | Journal of Integrative Plant Biology2016，58，6： | 4 |
| 4 | Multi-Environmental Genetic Analysis of Grain Size Traits Based on Chromosome Segment Substitution Line in Rice(Oryza sativa L.)显示文摘Grain size traits are critical agronomic traits which directly determine grain yield,but the genetic bases of these traits are still not well understood.In this study,a total of 154 chromosome segment substitution lines(CSSLs)population derived from a cross between a japonica variety Koshihikari and an indica variety Nona Bokra was used to investigate grain length(GL),grain width(GW),length-width ratio(LWR),grain perimeter(GP),grain area(GA),and thousand grain weight(TGW)under four environments.QTL mapping analysis of six grain size traits was performed by QTL IciMapping 4.2 with an inclusive composite interval mapping(ICIM)model.A total of 64 QTLs were identified for these traits,which mapped to chromosomes 1,2,3,4,6,7,8,10,11,and 12 and accounted for 1.6%–27.1%of the total phenotypic variations.Among these QTLs,thirty-six loci were novel and seven QTLs were identified under four environments.One locus containing the known grain size gene,qGL3/GL3.1/OsPPKL1,also have been found.Moreover,five pairs of digenic epistatic interactions were identified except for GL and GP.These findings will facilitate fine mapping of the candidate gene and QTL pyramiding to genetically improve grain yield in rice. | Yujia Leng Shuilian Wang Ruoan Wang Tao Tao Shuwen Jia Tao Song Lina Xu Xiuling Cai Sukui Jin Jiping Gao | 2022 | Phyton-International Journal of Experimental Botany2022，91，5： | 0 |
