FSD1 — Zea mays

Summary

ZM00001EB378880 (ZmFSD1, also known as ZmPAP9) encodes a manganese/iron superoxide dismutase (EC 1.15.1.1) with superoxide dismutase activity, as well as siRNA, miRNA and mRNA binding, RNA endonuclease activity, and protein kinase activity. The gene is associated with reactive oxygen species (ROS) homeostasis, removal of superoxide radicals, hydrogen peroxide metabolism, and responses to abiotic stresses including chilling, drought, salt, waterlogging, and metal stress. ZmFSD1 has been linked to numerous agronomic traits such as kernel number per ear, cob weight and length, grain moisture content, spike weight, stem dry weight, biological yield, leaf area and senescence, canopy light interception, and relative biomass. It localises to chloroplasts, thylakoids, mitochondria, and the cytosol, and is associated with chloroplast biogenesis, redox homeostasis, and root gravitropism.
