Abstract

Life Sciences & Biomedicine Plant Sciences Science & Technology
Plants perceive salt through plant salinity sensors In the past decade, much progress has been made in identifying the sensors involved in salt-induced stress signaling in plants. Plant roots are the first organs to detect changes in the osmotic potential induced by salt stress. Wang et al. have summarized the recent progress in identifying osmotic and Na + sensors and their signal transduction pathways, specifically in plant roots. Different types of putative sensors in the plasma membrane of root cells exist, including mechanosensory channels (MSCs), which respond to turgor pressure changes of plant cells, plasma membrane-bound protein kinases, which can phosphorylate signaling proteins, and Ca 2+-mediated ion transporters, such as non-selective cation channels (NSCCs) and cyclic nucleotide-gated channels (CNGCs) which, upon activation, allowing Ca 2+ to flow into cells. They have further performed bioinformatic analyses of transmembrane domains of receptor-like kinases (RLKs), which are considered as candidate ionic sensors.
