ERD5 — Brassica napus

Summary

BnERD5 (ERD5) on chromosome C02 of oilseed rape encodes a proline oxidase, a FAD-linked oxidoreductase with a proline dehydrogenase domain. The enzyme is localised to mitochondria and is associated with proline breakdown, spore germination, response to boron, heme anabolism, metabolic burst, response to AOS, cellular response to hypoxia, oxidative stress, and defence against bacteria. It has been linked to root and shoot fresh weight, net photosynthetic rate, proline content, and salt tolerance. Phenotypic associations include proline accumulation and metabolism, growth under water deficit, hypersensitive response, NADP/NADPH ratio, root elongation at low water potential, dehydration response, drought tolerance, and abiotic stress response. Studies of related genes in other species link the family to oxidative stress tolerance, salt tolerance, and response to dehydration.
