IOS1 — Phaseolus vulgaris

Summary

PvIOS1 (PHAVU_005G163000) on chromosome 5 of French bean encodes a protein with malectin-like and leucine-rich repeat domains and serine/threonine/tyrosine kinase activity. It is associated with pectin binding, ammonium channel activity, and red/far-red light photoreceptor activity. The gene is associated with downregulation of defense response to oomycetes, regulation of defense response by callose deposition, lateral root branching, response to flooding, and abscisic acid metabolism. Associations include yield, biomass, photosynthetic rate, water use efficiency, leaf angle, photoperiod-sensitive flowering time, biotic plant stress trait, glyphosate sensitivity, and root phototropism response trait. Studies of related genes in other species link the family to pattern-triggered immunity, disease susceptibility to Pseudomonas syringae and downy mildew, callose deposition, and ABA signaling.
