IOS1 — Phaseolus vulgaris

Summary

PHAVU_005G164100, designated PvIOS1, encodes a protein with a malectin-like domain and leucine-rich repeats, possessing protein tyrosine kinase, histidine kinase, and red/far-red light photoreceptor activities. It is associated with pectin binding, ammonium channel activity, and coreceptor activity. The gene is linked to downregulation of defense response to oomycetes, regulation of defense response by callose deposition, lateral root branching, endosperm development, abscisic acid metabolism, circadian regulation of calcium ion oscillation, and response to flooding, red light, and oomycetes. It is associated with yield, biomass, photosynthetic rate, water use efficiency, leaf angle, root phototropism, phosphorus uptake, and biotic stress. Studies of related genes in other species link the family to pattern-triggered immunity, resistance to Pseudomonas syringae, downy mildew susceptibility, callose deposition, and ABA signaling.
