Arabidopsisthaliana, etc ; chloroplasts; electron transfer; Show all 3 Subjects
Abstract:
... Cyclic electron transport/flow (CET/CEF) in chloroplasts is a regulatory process essential for the optimization of plant photosynthetic efficiency. A crucial CEF pathway is catalyzed by a membrane-embedded NADH dehydrogenase-like (NDH) complex that contains at least 29 protein subunits and associates with photosystem I (PSI) to form the NDH–PSI supercomplex. Here, we report the 3.9 Å resolution st ...

Abstract:
... RNA degradation is an important process for controlling gene expression and is mediated by decapping / deadenylation-dependent or endonucleolytic cleavage–dependent RNA degradation mechanisms. High-throughput sequencing of RNA degradation intermediates was initially developed in Arabidopsis thaliana and similar RNA degradome sequencing methods were conducted in other eukaryotes. However, interpret ...

Abstract:
... Intrinsic and exogenous signals in conjunction precisely regulate the initiation of flowering. Both signals influence flowering time, which is an integral part of plant reproduction. The signals converge through different pathways, and their coordinated action leads to the onset of flowering. Genetic pathways related to the regulation of flowering time are well-known from research into the molecul ...

Abstract:
... Plants in most natural habitats are exposed to a continuously changing environment, including fluctuating temperatures. Temperature variations can trigger acclimation or tolerance responses depending on the severity of the signal. To guarantee food security under a changing climate, we need to fully understand how temperature response and tolerance are triggered and regulated. Here, we put forward ...

Abstract:
... In a recent study of de novo mutations in arabidopsis (Arabidopsis thaliana), Monroe et al. found a lower mutation frequency inside gene bodies and certain essential genes, shattering the long-standing idea that mutations are entirely random across the genome. Here I highlight the molecular nonrandomness of mutations and the type of gene affected. ...

Abstract:
... MAIN CONCLUSION: Extracellular ATP level induced a transient increase during germination of Arabidopsis seeds, and extracellular ATP could negatively regulate the seed germination by its receptor, DORN1. Extracellular ATP (exATP) acts as a signal molecule for regulating growth, development, and responses of plants to external environments. In this study, we investigated the possible involvement of ...
