ERD5 — Brassica napus

Summary

BnERD5 (ERD5, also known as PRO1, PDH1, PRODH) on chromosome A02 of oilseed rape (Brassica napus) encodes a proline oxidase with a proline dehydrogenase domain and FAD-linked oxidoreductase-like structure. The enzyme localises to mitochondria and is associated with proline breakdown, spore germination, response to boron, heme anabolism, metabolic burst, response to AOS, cellular response to hypoxia, response to oxidative stress, defence response to bacteria, and response to thirst. It has been linked to root fresh weight, shoot fresh weight, net photosynthetic rate, proline content, proline accumulation, growth under water deficit, drought tolerance, dehydration response, hypersensitive response, NADP/NADPH ratio, root elongation at low water potential, and abiotic stress response. Studies of related genes in other species connect the family to leaf water potential, amino acid content, heterosis, osmotic response sensitivity, oxidative stress response, disease tolerance, freezing tolerance, salt tolerance, and reproductive development.
