IOS1 — Phaseolus vulgaris

Summary

PHAVU_005G164000 (PvIOS1) on chromosome 5 of French bean encodes a protein with a malectin-like domain, leucine-rich repeats, and serine/threonine kinase activity, and is annotated for pectin binding, ammonium channel activity, and red/far-red light photoreceptor activity. The gene is associated with downregulation of defense response to oomycetes, lateral root branching, endosperm development, abscisic acid metabolism, and response to flooding. It has been linked to yield, biomass, photosynthetic rate, water use efficiency, leaf angle, root phototropism, phosphorus uptake, and sensitivity to glyphosate, gibberellic acid, jasmonic acid, and UV-B light. Studies of related genes in other species connect the family to disease susceptibility, pattern-triggered immunity, callose deposition, ABA signaling, and shade avoidance.
