IOS1 — Phaseolus vulgaris

Summary

PHAVU_005G164400 (PvIOS1) encodes a protein with malectin-like and leucine-rich repeat domains and serine/threonine/tyrosine kinase activity, annotated as a transmembrane receptor protein tyrosine kinase with red/far-red light photoreceptor activity, pectin binding, ammonium channel activity, and histone H2AS1 kinase activity. In French bean, PvIOS1 is associated with downregulation of defense response to oomycetes, lateral root branching, regulation of defense response by callose deposition, response to flooding, endosperm development, abscisic acid metabolism, and circadian regulation of calcium ion oscillation. The gene is linked to traits including yield, biomass, photosynthetic rate, water use efficiency, leaf angle, phosphorus uptake, photoperiod-sensitive flowering time, biotic stress, and glyphosate sensitivity. Studies of related genes in other species connect the family to pattern-triggered immunity, disease resistance to bacteria, callose deposition, abscisic acid signaling, and phototropic response.
