20 小时之前 · The ndhD-2 site lies within the translation initiation codon of ndhD transcript and a defect in ndhD-2 editing dramatically impairs the accumulation of the NDH ... We purified MORF8 of rice ...

2024年12月1日 · In rice, the OsTRX z gene mutation results in a high-temperature-sensitive albinic phenotype and altered editing efficiencies in many chloroplast sites, such as ndhA, ndhB, rpoB, rps8 and ndhF (Wang et al., 2021), implying the tightly relationship between heat stress response and chloroplast RNA editing. At the same time, thioredoxin z ...

2005年1月20日 · Eleven subunits of the complex are encoded in the chloroplast genome in higher plants (ndhA – ndhK). We developed a screening system to identify mutants with impaired NDH activity in Arabidopsis...

2016年7月1日 · Cyclic electron flow around photosystem I via chloroplast NAD(P)H dehydrogenase (NDH) complex performs a significant physiological role during photosynthesis and plant growth at low temperature in rice

2018年5月25日 · Here, we identified a rice dual-localized PPR protein, OsPGL1. The loss of function of OsPGL1 resulted in defects in both chloroplast RNA editing of ndhD-878 and mitochondrial RNA editing of ccmFc-543, both of which could be restored in transgenic complementation lines.

高等植物NDH复合体介导的围绕PSI的循环电子传递 (CET-PSI)是植物适应各种自然环境胁迫所产生的一个十分重要的保护机制。 由于C4植物CO2浓缩机制需要额外ATP,其CET能力强于C3植物。 NDH的表达变化是造成C4植物和C3植物CET强弱差异的主要因素。 在三大粮食作物中,玉米和水稻分别属于C4和C3植物。

2024年7月22日 · Our results indicate that NDH-mediated CEF is the primary electron transport route in BS chloroplasts highlighting the essential role of NDH in generating ATP required for CO 2 fixation by the C 3 cycle in BS cells.

2021年10月21日 · 本文主要综述了目前植物中基于PPR基因家族等编辑复合体以及动物中关于CRISPR/Cas系统的两种RNA编辑系统,并介绍了RNA编辑在植物生长发育过程中的重要作用,并展望了RNA编辑研究的未来应用前景。 此外,本文总结了关于RNA编辑数据库的最近研究进展,为后续的RNA编辑研究提供一定的理论参考。 RNA editing is a post-transcriptional process on the target transcripts by base insertion,deletion,or replacement.

The carboxyterminal end of the NDH-H subunit from rice (Oryza sativa L.) was expressed as a fusion protein in Escherichia coli and antibodies against the fusion protein were generated in rabbits.

RNA editing has been observed in chloroplast transcripts from most land plants, but not from algae. In higher plant chloroplasts, C-to-U conversion occurs at around 30 specific sites in mRNAs, many of which result in amino acid alteration. Occasionally, RNA editing creates an AUG initiation codon from ACG, and a UAA termination codon from CAA.
