GLYMA_04G017500V4 — Glycine max

Summary

GmCAT (GLYMA_04G017500V4) on soybean chromosome 4 encodes a catalase-family protein, characterized by catalase core, haem-binding and immune-responsive domains, and annotated with heme binding, protein kinase activity, and nucleoside diphosphate kinase activity. The gene is associated with peroxisomal lumen localization and linked to heme breakdown, glyoxylate metabolism, and chlororespiration. GmCAT has been connected to numerous agronomic traits, such as net photosynthetic rate, relative chlorophyll content, leaf water potential, seedling vigor, root and shoot biomass, cell membrane stability, and flavonoid content. It is also associated with phenotypes including oxidative stress tolerance, hydrogen peroxide accumulation, stomatal closure, seed germination, and immunity-triggered cell death. Studies of related genes in other species link the family to catalase activity, peroxisomal protein import, and disease resistance.
