| 1 | TSC1 enables plastid development under dark conditions, contributing to rice adaptation to transplantation shock显示文摘Since its domestication from wild rice thousands of years ago, rice has been cultivated largely through transplantation. During transplantation from the nursery to the paddy field, rice seedlings experience transplantation shock which affects their physiology and production.However, the mechanisms underlying transplantation shock and rice adaptation to this shock are largely unknown. Here,we isolated a transplant-sensitive chloroplast-deficient(tsc_1)rice mutant that produces albino leaves after transplantation.Blocking light from reaching the juvenile leaves and leaf primordia caused chloroplast deficiencies in transplanted tsc_1 seedlings. TSC_1 encodes a noncanonical adenosine triphosphate-binding cassette(ABC) transporter homologous to At NAP_(14) and is of cyanobacterial origin. We demonstrate that TSC_1 controls plastid development in rice under dark conditions, and functions independently of light signaling.However, light rescued the tsc_1 mutant phenotype in a spectrum-independent manner. TSC_1 was upregulated following transplantation, and modulated the iron and copper levels, thereby regulating prolamellar body formation during the early P_4 stage of leaf development. Therefore, TSC_1 is indispensable for plastid development in the absence of light,and contributes to adaptation to transplantation shock.Our study provides insight into the regulation of plastid development and establishes a framework for improving recovery from transplantation shock in rice. | Xiaoliang Shi Sunlu Chen Yu Peng Yufeng Wang Jiugeng Chen Zhanghua Hu Baohe Wang Aihong Li Daiyin Chao Yuhong Li Sheng Teng | 2018 | Journal of Integrative Plant Biology2018，60，2： | 2 |
| 2 | Structure and mechanism of a group-I cobalt energy coupling factor transporter显示文摘联合精力的因素(ECF ) transporters 是最近在微生物识别的 ATP 有约束力的盒子 transporters 的一个大家庭。为从环境的微量元素举起负责, ECF transporters 是由膜底层绑定部件 EcfS 和由不可分的膜支架部件 EcfT 和二细胞质的 ATP 绑定 / 水解作用的部件 EcfA/A 组成的一个 ECF 模块组成的模块化的 transporters。ECF transporters 被分类进组我和 II。当前,组的分子的理解 -- 我 ECF transporters 很被限制,部分由于 transporter 的缺乏复杂结构的信息。这里,我们现在的结构和这个组的基于结构的分析 -- 我钴 ECF transporter CbiMNQO,谁的组成的子单元 CbiM/CbiN, CbiQ,和 CbiO 分别地对应于 group-II ECF transporters 的 EcfS, EcfT,和 EcfA 部件。通过不同 CbiMNQO 子单元的宪法和相关 ATPase 和 transporter 活动的决心,底层绑定子单元 CbiM 被发现刺激 CbiQOs 基础 ATPase 活动。CbiMQO 建筑群的结构在它的里面打开符合构造和 CbiO 的被决定在, -methyleneadenosine 第 5-triphosphate-bou 关上的符合构造。基于结构的分析揭示了在不同部件, CbiM 的 L1 循环的底层门函数,和 ATP 绑定和产品版本在 CbiMNQO transporter 建筑群以内导致的 CbiO 的 conformational 变化之间的相互作用。这些调查结果使我们能建议 CbiMNQO transporter,运输过程在要求旋转的一个工作模型或倒下 CbiQ 和 CbiM,和在联合 conformational 的 CbiN 力量功能在 CbiQ 和 CbiM 之间变化。 | Zhihao Bao Xiaofeng Qi Sen Hong Ke Xu Fangyuan He Minhua Zhang Jiugeng Chen Daiyin Chao Wei Zhao Dianfan Li Jiawei Wang Peng Zhang | 2017 | Cell Research2017，27，5： | 1 |
