IOS1 — Phaseolus vulgaris

Summary

PvIOS1 (PHAVU_005G163500) on chromosome 5 of French bean encodes a protein with a malectin-like domain, leucine-rich repeats, and a serine/threonine/tyrosine kinase catalytic domain, annotated with protein tyrosine kinase, red/far-red light photoreceptor, and ammonium channel activities. The gene is associated with downregulation of defense response to oomycetes, regulation of defense by callose deposition, lateral root branching, endosperm development, abscisic acid metabolism, and responses to flooding, red light, and hydrogen peroxide. It localizes to the membrane, plasmodesma, pollen tube, and nuclear body. Associations include yield, biomass, photosynthetic rate, water use efficiency, leaf angle, photoperiod-sensitive flowering, glyphosate sensitivity, salt tolerance, bacterial and downy mildew resistance, ammonium transport, and shade avoidance. Related genes in other species are linked to disease resistance, phototropic response, thermotolerance, and circadian period.
