CAT1 — Brassica juncea

Summary

BJUA06G28350S (CAT1, also known as BjCAT3) encodes a catalase family protein with catalase domains and heme binding, and is annotated with S-nitrosylase, nucleoside diphosphate kinase, histone acetyltransferase, and DNA-binding transcription factor activities. In Indian mustard, it is associated with hydrogen peroxide catabolism, cellular responses to hydrogen peroxide and superoxide, regulation of programmed cell death, systemic acquired resistance, aerenchyma formation, and responses to oomycetes and nutrient starvation. The gene is linked to leaf chlorosis, biomass yield, photosynthetic rate, seed yield, water use efficiency, root length and thickness, stomatal closure, disease tolerance, salt tolerance, low temperature stress response, and chloroplast development. It localizes to the peroxisomal lumen, tonoplast, chloroplast envelope, and apoplast. Related genes in other species are linked to catalase activity, cell death regulation, and stress responses.
