IOS1 — Phaseolus vulgaris

Summary

PHAVU_005G162600, designated PvIOS1 on chromosome 5 of French bean (Phaseolus vulgaris), encodes a protein with a malectin-like domain, leucine-rich repeats, and a serine/threonine/tyrosine kinase catalytic domain. The gene product is annotated with pectin binding, ammonium channel activity, and red/far-red light photoreceptor activity. PvIOS1 is associated with downregulation of defense response to oomycetes, lateral root branching, regulation of defense by callose deposition, response to flooding, endosperm development, abscisic acid metabolism, and leaf senescence. It is linked to yield, biomass, photosynthetic rate, water use efficiency, leaf angle, root phototropism, and responses to light, flooding, and biotic stress. Related genes in other species are associated with pattern-triggered immunity, callose deposition, resistance to Pseudomonas syringae, downy mildew susceptibility, and abscisic acid signaling.
