| 1 | Photoperiod- and thermo-sensitive genic male sterility in rice are caused by a point mutation in a novel noncoding RNA that produces a small RNA显示文摘光周期敏感、 thermo 敏感的遗传因子的男绝育(PGMS 和 TGMS ) 是为在庄稼的混合繁殖的核心部件。基于使用的较普通活字大一倍的系统, PGMS 和 TGMS 衬里的混合大米是成功地在农业广泛地发展了并且适用。然而,位于 PGMS 和 TGMS 的控制下面的分子的机制仍然保持阴暗。在这研究,我们印射并且克隆一个主要地点, p/tms12-1 (染色体 12 上的感光性或 thermo 敏感的遗传因子的男绝育地点) 它在装饰用的梨树米饭线 Nongken 58S (NK58S ) 授与 PGMS 和在 indica 米饭的 TGMS 衬里 Peiai 64S (PA64S,源于 NK58S ) 。包含野类型的等位基因 P/TMS12-1 的 A 2.4-kb DNA 碎片能在基因互补恢复 NK58S 和 PA64S 植物的花粉富饶。P/TMS12-1 编码唯一的 noncoding RNA,它生产 21 核苷酸我们说出 osa-smR5864w 的小 RNA。在 p/tms12-1 的 C-to-G 的替换,相对 P/TMS12-1 的唯一的多型性,在变异的小 RNA 是在场的,也就是 osa-smR5864m。而且,在转基因的 NK58S 和 PA64S 植物的 P/TMS12-1 的一个 375-bp 序列的 overexpression 也生产了 osa-smR5864w 并且恢复了花粉富饶。小 RNA 在年轻圆锥花序优先地被表示,但是它的表示没被不同的天长度或温度显著地影响。我们的结果表明在 p/tms12-1 的点变化,可能为 osa-smR5864m 导致 loss-of-function,分别地在装饰用的梨树和 indica 线为 PGMS 和 TGMS 组成一个普通原因。我们的调查结果因此建议那小 RNA 基因是的这 noncoding 男开发的一个重要管理者由在基因网络和环境条件之间的串音控制了。 | Hai Zhou Qinjian Liu Jing Li Dagang Jiang Lingyan Zhou Ping Wu Sen Lu Feng Li Liya Zhu Zhenlan Liu Letian Chen Yao-Guang Liu Chuxiong Zhuang | 2012 | Cell Research2012，22，4： | 99 |
| 2 | MAPPING OF THE RICE (ORYZA SATIVA L.) THERMO-SENSITIVE GENIC MALE STERILE GENE TMS5 WITH EST AND SSR MARKERS显示文摘With the cDNA suppression subtraction hybridization method, a spikelet-specific cDNA library was constructed that expressed at meiosis stage in rice. A total of 121 cDNA fragments were selected from the library and used as EST (expressed se-quence tags) markers to detect the polymorphism between Annong N, a normal fertile Indica rice line and Annong S-1, its spontaneous mutant with thermo-sensitive genic male sterility, using the RFLP (restriction fragment length polymorphism) technique. HN57, one of the EST probes, could detect poly-morphism between them. The results of segregation analysis with the F2 population developed from An-nong S-1 and Annong N indicate that HN57 co-seg- regates with the thermo-sensitive genic male-sterility controlled by tms5, the recessive gene in Annong S-1. This marker is located on the 31.2-cM region of the chromosome 2 of RGP (rice genome research pro-gram) genetic map. To further determine the location of tms5, 80 SSR (simple sequence repeat) markers around this region were developed, and 12 of them were polymorphic. And finally, the tms5 was mapped within region of 181 kb by using these new markers. | JIANG Dagang LU Sen ZHOU Hai WU Xiaojin ZHUANG Chuxiong LIU Yaoguang | 2006 | Chinese Science Bulletin2006，51，4： | 10 |
| 3 | Ranking environmental projects model based on multicriteria decision-making and the weight sensitivity analysis显示文摘With the fast growth of Chinese economic,more and more capital will be invested in environmental projects.How to select the environmental investment projects (alternatives) for obtaining the best environmental quality and economic benefits is an important problem for the decision makers.The purpose of this paper is to develop a decision-making model to rank a finite number of alternatives with several and sometimes conflicting criteria.A model for ranking the projects of municipal sewage treatment plants is proposed by using exports' information and the data of the real projects.And,the ranking result is given based on the PROMETHEE method. Furthermore,by means of the concept of the weight stability intervals (WSI),the sensitivity of the ranking results to the size of criteria values and the change of weights value of criteria are discussed.The result shows that some criteria,such as'proportion of benefit to project cost',will influence the ranking result of alternatives very strong while others not.The influence are not only from the value of criterion but also from the changing the weight of criterion.So,some criteria such as'proportion of benefit to project cost'are key critera for ranking the projects. Decision makers must be cautious to them. | Jiang Yan Tian Dagang Pan Yue | 2007 | Journal of Systems Engineering and Electronics2007，18，3： | 5 |
| 4 | Methylesterification of cell-wall pectin controls the diurnal flower-opening times in rice显示文摘Flowers are the core reproductive organ of plants, and flowering is essential for cross-pollination. Diurnal flower-opening time is thus a key trait influencing reproductive isolation, hybrid breeding, and thermostability in plants. However, the molecular mechanisms controlling this trait remain unknown. Here, we report that rice Diurnal Flower Opening Time 1 (DFOT1) modulates pectin methylesterase (PME) activity to regulate pectin methylesterification levels of the lodicule cell walls, which affect lodicule swelling to control diurnal flower-opening time. DFOT1 is specifically expressed in the lodicules, and its expression gradually increases with the approach to flowering but decreases with flowering. Importantly, a knockout of DFOT1 showed earlier diurnal flower opening. We demonstrate that DFOT1 interacts directly with multiple PMEs to promote their activity. Knockout of PME40 also resulted in early diurnal flower opening, whereas overexpression of PME42 delayed diurnal flower opening. Lower PME activity was observed to be associated with higher levels of pectin methylesterification and the softening of cell walls in lodicules, which contribute to the absorption of water by lodicules and cause them to swell, thus promoting early diurnal flower opening. Higher PME activity had the opposite effect. Collectively, our work uncovers a molecular mechanism underlying the regulation of diurnal flower-opening time in rice, which would help reduce the costs of hybrid breeding and improve the heat tolerance of flowering plants by avoiding higher temperatures at anthesis. | Mumei Wang Xiaopei Zhu Guoqing Peng Minglong Liu Shuqing Zhang Minghao Chen Shitang Liao Xiaoying Wei Peng Xu Xiyu Tan Fangping Li Zhichuan Li Li Deng Ziliang Luo Liya Zhu Shuai Zhao Dagang Jiang Jing Li Zhenlan Liu Xianrong Xie Shaokui Wang Aimin Wu Chuxiong Zhuang Hai Zhou | 2022 | Molecular Plant2022，15，6： | 2 |
