MSD1 — Brassica oleracea

Summary

BoMSD1 (BOLC102_C01P059710.1) on cabbage chromosome 1 encodes a manganese/iron superoxide dismutase, a mitochondrial and cytosolic enzyme that binds manganese and copper. The gene is associated with oxidative stress response, antioxidant defense, and reactive oxygen species accumulation, as well as with abscisic acid signaling, embryo development, seed dormancy, and responses to herbicides, xenobiotics, and zinc. It has been linked to seedling vigor, arsenic tolerance, and superoxide dismutase activity. Related genes in other species are associated with root growth, mitochondrial redox homeostasis, tricarboxylic acid cycle flux, and root morphology traits including root width, length, and number.
