CAT1 — Oryza sativa Indica Group

Summary

BGIOSGA040139 (CAT1) in Indica rice encodes a protein with catalase core, catalase immune-responsive, catalase haem-binding, and catalase superfamily domains, and is annotated with multiple molecular functions including S-nitrosylase activity, nucleoside diphosphate kinase activity, histone acetyltransferase activity, and heme binding. The gene is associated with peroxisomal lumen localisation and a wide range of biological processes including cellular response to hydrogen peroxide, response to superoxide, cellular oxidant detoxification, cell redox homeostasis, regulation of programmed cell death, and regulation of ethene mediated signaling pathway. It has been linked to numerous agronomically important traits such as grain filling period, seed yield, biomass yield, photosynthetic rate, cadmium concentration, disease tolerance, low temperature stress response, root length, and leaf chlorosis. Related genes in other species are linked to catalase activity, peroxisomal function, and stress responses.
