CSD1 — Glycine max

Summary

GmCSD1 (GLYMA_19G240400V4) on soybean chromosome 19 encodes a protein with SOD_Cu_Zn domains and copper binding activity. The enzyme is associated with superoxide dismutase activity and D-lactate dehydratase function. This gene is linked to cellular responses to oxidative stress, ozone, UV-B, copper, chitin, and bacterial molecules, as well as gene silencing by miRNA. It localizes to the cytosol, nucleus, plasmodesma, and extracellular regions. GmCSD1 has been connected to drought tolerance, salt tolerance, bacterial blight disease resistance, photosynthetic rate, chlorophyll content, cell membrane stability, and stomatal closure. It is also associated with copper homeostasis, antioxidant activity, and responses to high light, arsenic, and thermotolerance. Studies of related genes in other species link the family to superoxide detoxification, bacterial and fungal disease resistance, and innate immunity.
