RecA maintains the integrity of chloroplast DNA molecules in Arabidopsis
Although our understanding of mechanisms of DNA repair in bacteria and eukaryotic nuclei continues to improve, almost nothing is known about the DNA repair process in plant organelles, especially chloroplasts. Since the RecA protein functions in DNA repair for bacteria, an analogous function may exist for chloroplasts. The effects on chloroplast DNA (cpDNA) structure of two nuclear-encoded, chl...
متن کاملThe Arabidopsis synaptotagmin1 is enriched in endoplasmic reticulum-plasma membrane contact sites and confers cellular resistance to mechanical stresses.
Eukaryotic endoplasmic reticulum (ER)-plasma membrane (PM) contact sites are evolutionarily conserved microdomains that have important roles in specialized metabolic functions such as ER-PM communication, lipid homeostasis, and Ca(2+) influx. Despite recent advances in knowledge about ER-PM contact site components and functions in yeast (Saccharomyces cerevisiae) and mammals, relatively little ...
متن کاملArabidopsis synaptotagmin 1 is required for the maintenance of plasma membrane integrity and cell viability.
Plasma membrane repair in animal cells uses synaptotagmin 7, a Ca(2+)-activated membrane fusion protein that mediates delivery of intracellular membranes to wound sites by a mechanism resembling neuronal Ca(2+)-regulated exocytosis. Here, we show that loss of function of the homologous Arabidopsis thaliana Synaptotagmin 1 protein (SYT1) reduces the viability of cells as a consequence of a decre...
متن کاملArabidopsis leaf plasma membrane proteome using a gel free method: Focus on receptor–like kinases
The hydrophobic proteins of plant plasma membrane still remain largely unknown. For example in the Arabidopsis genome, receptor-like kinases (RLKs) are plasma membrane proteins, functioning as the primary receptors in the signaling of stress conditions, hormones and the presence of pathogens form a diverse family of over 610 genes. A limited number of these proteins have appeard in pr...
متن کاملPlasma membrane proteome in Arabidopsis and rice.
Plant cells contain many membrane systems that are specially adapted to perform particular functions. In plant cells, the processing of signals that are involved in responses to biotic and abiotic stressors occurs in the plasma membrane. Therefore, characterization of the plasma membrane proteome can provide new insights into the functions of various plant membrane systems. Plant plasma membran...
