PH1 — Phaseolus vulgaris

Summary

PvPH1 (PHAVU_007G272100) on chromosome 7 of French bean encodes a protein with protein-binding activity, belonging to the At4g14450 domain family. The gene is associated with multiple biological processes including parturition, embryogenesis, defense responses to other organisms, cellular response to hypoxia, response to water, and post-translational modification. Its product localizes to the cytoplasm, nucleus, and mitochondria. PvPH1 is associated with hypoxia tolerance. Studies of related genes in other species link the family to pathogen resistance, as well as to traits such as seed coat pattern, disease tolerance, photochemical quenching, and salt tolerance, and to phenotypes including wilted leaves after submergence and increased ROS production under hypoxia.
