CAT1 — Oryza sativa Indica Group

Summary

BGIOSGA039824 (CAT1) in Indica rice encodes a protein with catalase core and haem-binding domains, and is annotated with multiple molecular functions including S-nitrosylase, nucleoside diphosphate kinase, histone acetyltransferase, and heme-binding activities. It is associated with cellular responses to hydrogen peroxide and superoxide, cell redox homeostasis, regulation of programmed cell death, and photoperiodism, and localises to the peroxisomal lumen, chloroplast envelope, tonoplast, and apoplast. The gene has been linked to agronomically important traits including seed yield, grain filling period, biomass yield, photosynthetic rate, root length, cadmium concentration, nitrate uptake, disease tolerance, and low temperature stress response. Studies of related genes in other species connect the family to catalase activity, stress response, and disease resistance.
