MSD1 — Glycine max

Summary

GmMSD1 (GLYMA_04G221300V4) on soybean chromosome 4 encodes a manganese/iron superoxide dismutase, a family member that binds manganese, copper, and other metals. The gene is associated with removal of superoxide radicals, response to oxidative stress, reactive oxygen species anabolism, and metabolic burst. It has been linked to mitochondrial localization and to traits including drought tolerance, photosynthetic rate, chlorophyll content, stomatal resistance, cell membrane stability, manganese concentration, and protein content. Associations also include embryo sac development, floral organ abscission timing, root architecture, and responses to arsenic, herbicides, and zinc. Studies of related genes in other species connect the family to superoxide detoxification, mitochondrial redox homeostasis, and root growth.
