IOS1 — Phaseolus vulgaris

Summary

PvIOS1 (PHAVU_005G164300) on chromosome 5 of French bean encodes a transmembrane receptor 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 linked to downregulation of defense response to oomycetes, regulation of defense response by callose deposition, lateral root branching, response to flooding, and abscisic acid metabolism. Associations with yield, biomass, photosynthetic rate, water use efficiency, leaf angle, root phototropism, and photoperiod-sensitive flowering time have been noted. Related genes in other species are linked to disease susceptibility, pattern-triggered immunity, callose deposition, abscisic acid signaling, ammonium transport, phototropic response, and biomass production.
