ERD5 — Brassica napus

Summary

BnERD5 (also known as PRO1, PDH1, or ERD5) on chromosome A06 of oilseed rape (Brassica napus) encodes a proline oxidase with a proline dehydrogenase domain and FAD-linked oxidoreductase-like structure. The enzyme is localized to mitochondria and has proline oxidase activity. This gene is associated with proline breakdown, proline accumulation, proline metabolism, and proline homeostasis. It is linked to drought tolerance, growth under water deficit, root elongation at low water potential, and dehydration response. Associations also include net photosynthetic rate, leaf water potential, shoot and root fresh weight, seed maturation, heterosis, and salt tolerance. Additional connections involve response to water, hypoxia, boron, and stimulus, along with regulation of lipogenesis, triglyceride anabolism, and the TCA cycle. Studies of related genes in other species link the family to oxidative stress tolerance, salt tolerance, freezing tolerance, and pathogen defense.
