CAT1 — Oryza sativa Indica Group

Summary

BGIOSGA038595 (CAT1) in Indica rice encodes a protein with catalase domains, including catalase core, haem-binding, and immune-responsive domains, and is annotated with multiple molecular functions including S-nitrosylase, nucleoside diphosphate kinase, and histone acetyltransferase activities. The gene is associated with cellular nitric oxide homeostasis, S-transnitrosylation, response to hydrogen peroxide and superoxide, cell redox homeostasis, and peroxisomal localization. It has been linked to a wide range of agronomic traits including seed shape and yield, grain filling period, biomass yield, photosynthetic rate, root length and thickness, leaf chlorosis, cadmium concentration, nitrate uptake, and responses to biotic and abiotic stresses such as low temperature and disease tolerance. Related genes in other species link the family to catalase activity, stress response, disease resistance, and peroxisomal function.
