IOS1 — Phaseolus vulgaris

Summary

PvIOS1 (PHAVU_005G162500) 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. The gene is associated with pectin binding, ammonium channel activity, and red/far-red light photoreceptor activity. It is linked to downregulation of defense response to oomycetes, lateral root branching, response to flooding, endosperm development, abscisic acid metabolism, and circadian regulation of calcium ion oscillation. Associations with agronomic traits include yield, biomass, photosynthetic rate, water use efficiency, leaf angle, root phototropism, photoperiod-sensitive flowering, and responses to biotic stress, glyphosate, jasmonic acid, and gibberellic acid. Studies of related genes in other species link the family to disease susceptibility, pattern-triggered immunity, callose deposition, and abscisic acid signaling.
