ERD5 — Phaseolus vulgaris

Summary

PHAVU_008G022000, designated PvERD5 (also known as PvPRODH, PDH1, and PDH2) on French bean chromosome 8, encodes a protein with a proline dehydrogenase domain and FAD-linked oxidoreductase-like domain, and is annotated with proline oxidase activity. The gene is associated with proline breakdown, the cellular response to hypoxia, response to oxidative stress, osmotic response, defence response to bacteria, and dehiscence. The product localises to mitochondria. PvERD5 is associated with photosynthetic rate, proline accumulation, proline metabolism, growth under water deficit, root elongation at low water potential, NADP/NADPH ratio, dehydration response, drought tolerance, and the hypersensitive response. Studies of related genes in other species connect the family to seed hardness, leaf chlorophyll content, biomass yield, seed weight and size, transpiration rate, stomatal resistance and opening, root length, disease tolerance, salt tolerance, freezing tolerance, and oxidative stress tolerance.
