ERD5 — Brassica oleracea

Summary

BoERD5 (ERD5, PRO1, PDH1) on cabbage chromosome 2 encodes a proline oxidase, a FAD-linked oxidoreductase with a proline dehydrogenase domain, and is localised to mitochondria. The gene is directly annotated to proline oxidase activity and proline breakdown, as well as to glucosinolate anabolism, secondary metabolism, homeostasis, cellular response to hypoxia, response to oxidative stress, defence response to bacteria, and response to thirst. It is associated with proline content and accumulation, photosynthetic rate, salt tolerance (SALTTL), 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, response to dehydration, freezing tolerance, disease resistance, PAMP-triggered immunity, and traits such as root and shoot fresh weight, net photosynthetic rate, leaf water potential, and heterosis.
