| 1 | Heteroexpression of the wheat phytochelatin synthase gene (TaPCS1) in rice enhances cadmium sensitivity显示文摘Phytochelatin synthase (PCS )(EC 2.3.2.15 ) 催化 phytochelatins (PC ) 的最后的步生合成。PC 是在植物在重金属的隐遁和 detoxification 起一个重要作用的充满半胱氨酸的 thiol 反应、重的金属绑定肽的一个家庭。以前的研究显示了那种显示的那 overexpressed PCS 对比显型,从提高的镉(Cd )忍耐到在 Arabidopsis thaliana 的 Cd 超敏性。在这研究,小麦 phytochelatin synthase 基因, TaPCS1,是在野类型的米饭的 heteroexpressed (Oryza sativa L. , cv。Zhonghua 11 ) 在米饭评估在 PC 和 Cd 忍耐的合成之间的关系。数据证明在米饭的 TaPCS1 的 heteroexpression 提高了 Cd 敏感并且显著地在射击,然而并非在根增加了 Cd 累积。另外, PCS 线在射击展出了 PC 和非蛋白质 thiols (NPT ) 的一个高得多的内容。在导致的 NPT 作文的突出的变化在射击在房间细胞器减少了谷胱甘肽水池弄空和更高的 Cd 内容,由更高氧化的应力列在后面,它可能导致 Cd 敏感。因此,在米饭的 TaPCS1 的 heteroexpression 能够在米饭射击增加 Cd 累积并且提高 Cd 敏感。 | Feijuan Wang Zhubing Wang Cheng Zhu | 2012 | Acta Biochimica et Biophysica Sinica2012，44，10： | 8 |
| 2 | Effects of Exogenous 5-Aminolevulinic Acid and 24-Epibrassinolide on Cd Accumulation in Rice from Cd-Contaminated Soil显示文摘High grain-Cd-accumulating rice variety Yongyou 9 was planted in Cd-contaminated farmland in Taizhou City, Zhejiang Province, China to study the effects of 5-aminolevulinic acid(ALA) and24-epibrassinolide(EBR) on Cd accumulation in brown rice. Results showed that the exogenous ALA and EBR had no significant effects on agronomic traits, soil pH and total Cd content in soil, but had some effects on the available Cd content in soil, and significantly influenced the Cd accumulation in the different parts of rice. Results also showed that 100 mg/L exogenous ALA significantly reduced the Cd accumulation in brown rice to blow the food safety standard(0.2 mg/kg), and also significantly reduced the Cd contents in the roots and culm of rice. However, 200 mg/L exogenous ALA treatment increased the Cd content in brown rice remarkably. In addition, 0.15 mg/L EBR treatment increased Cd accumulation in roots, culm, leaves and brown rice notably, whereas 0.30 mg/L exogenous EBR treatment reduced the Cd accumulation in brown rice properly, but it was not significant. Therefore,proper concentration of ALA can effectively reduce the Cd accumulation in brown rice, which can be used as an effective technical method for the safe production of rice in Cd polluted farmland. | WANG Feijuan ZHANG Yiting GUO Qinxin TAN Haifeng HAN Jiahui LIN Haoran WEI Hewen XU Guangwei ZHU Cheng | 2018 | Rice science2018，25，6： | 3 |
| 3 | Comparative proteomic study and functional analysis of translationally controlled tumor protein in rice roots under Hg^(2+) stress显示文摘So far,very little is known about mercury stress-induced intercellular metabolic changes in rice roots at the proteome level.To investigate the response of rice roots to mercury stress,changes in protein expression in rice roots were analyzed using a comparative proteomics approach.Six-leaf stage rice seedlings were treated with 50 μmol/L HgCl2 for 3 hr;29 protein spots showed a significant changes in abundance under stress when compared with the Hg2+-tolerant rice mutant and wild type(Zhonghua 11).Furthermore,all these protein spots were identified by mass spectrometry to match 27 diverse protein species.The identified proteins were involved in several processes,including stress response,redox homeostasis,signal transduction,regulation and metabolism;some were found to be cellular structure proteins and a few were unknown.Among the up-regulated proteins,OsTCTP(translationally controlled tumor protein) was chosen to perform hetereologous expression in yeast which was presumed to participate in the Hg2+ tolerance of rice,providing evidence for its role in alleviating Hg2+ damage.Among the many tests,we found that OsTCTP-overexpressed yeast strains were more resistant to Hg2+ than wild-type yeast.Thus,we propose that OsTCTP contributes to Hg2+ resistance.Here we present,for the first time,the functional characterization of OsTCTP in connection with Hg2+ stress in plants. | Feijuan Wang Yongshen Shang Ling Yang Cheng Zhu | 2012 | Journal of Environmental Sciences2012，24，12： | 2 |
