IOS1 — Phaseolus vulgaris

Summary

PHAVU_005G164200, designated PvIOS1, encodes a protein with malectin-like and leucine-rich repeat domains, annotated with transmembrane receptor protein tyrosine kinase activity, red/far-red light photoreceptor activity, and pectin binding. In French bean, it is associated with downregulation of defense response to oomycetes, regulation of defense response by callose deposition, lateral root branching, response to flooding, endosperm development, and abscisic acid metabolism. It localizes to the membrane, plasmodesma, pollen tube, and nuclear body. The gene is linked to yield, biomass, photosynthetic rate, water use efficiency, leaf angle, phosphorus uptake, photoperiod-sensitive flowering, and biotic stress traits. Related genes in other species are associated with disease resistance, callose deposition, ABA signaling, and shade avoidance.
