PH1 — Phaseolus vulgaris

Summary

PvPH1 (PHAVU_007G129450) on chromosome 7 of French bean encodes a protein with protein-binding activity, belonging to the At4g14450 domain family. The gene is associated with parturition, embryogenesis, response to water, defense responses to other organisms, cellular response to hypoxia, and post-translational modification. Its product localizes to mitochondria, cytoplasm, and nucleus. PvPH1 is linked to hypoxia tolerance and has been connected to the related genes PRP and PH2. Studies of related genes in other species link it to pathogen resistance in tomato and to traits including seed coat pattern, disease tolerance, photochemical quenching, and salt tolerance, as well as phenotypes such as wilted leaves after submergence and increased ROS production under hypoxia.
