Source: Institute of Genetics and Developmental Biology Date: 2018-06-22 【 Title : Xiaozhong University 】(Translated from the original Chinese by Google) The angle of tillering is the angle between the tiller and the main stem of the grass family and is closely related to the crop population. The analysis of the molecular mechanism of rice […]
During seedling greening, chloroplasts are formed from proplastids. Liang and Zhu et al. used a combination of 3D electron tomography of cryo-fixed Arabidopsis cotyledons at various times after illumination to track their development. The fine structure images, accompanied by transcriptomic analysis and immunogold labelling studies, provide a detailed picture of the developmental changes that occur […]
Plants have many proteins found in the light-harvesting complex, whereas cyanobacteria have only the high-light-inducible proteins (Hlips). One-helix proteins (OHPs) are the plant homologs of Hlips, but their precise functions have been unclear. Hey and Grimm used genetic and biochemical approaches to explore OHP function in Arabidopsis. The two Arabidopsis OHPs, OHP1 and OHP2, heterodimerize […]
The angle at which leaves extend are held in a rice plant (tiller angle) affects the plant’s ability to intercept light and therefore potential yield. Genetic studies have identified a few genes involved in tiller angle, including the LAZY1 gene that encodes a protein involved in auxin transport. To identify other genes involved in this […]
Potato is susceptible to many pathogens. To facilitate breeding programs, Ramšak et al. combined transcriptomic data from potato/virus interactions with a defense network model developed mainly from Arabidopsis. Their model revealed a previously undescribed interaction between ethylene and salicylate signalling, involving the direct transcriptional regulation of NPR1 by EIN3, indicating that transcriptional as well as […]
Auxin methylation is required for differential growth in Arabidopsis Plants need to navigate and adjust their growth according to the environmental clues, such as light or gravity. Asymmetric distribution of auxin is necessary for organ bending. Abbas and colleagues show that conversion of indole-3-acetic acid (IAA) into methyl-IAA (Me-IAA) is important for asymmetric auxin distribution. […]

Plant Physiology recently published a Focus Issue on Cell Dynamics. We asked the editors involved to tell us about what is meant by Cell Dynamics and why this topic is interesting and relevant, as well as about the Focus Issue program in general. This 11-minute video features Editor-in-Chief Mike Blatt (University of Glasgow), and Issue […]
