CAT1 — Magnaporthe oryzae 70-15

Summary

MGG_06442, designated MoCAT1 on chromosome 4 of Magnaporthe oryzae 70-15, encodes a catalase (EC 1.11.1.6) with heme-binding and metal-binding activity, belonging to the clade 2 catalase family. The gene is associated with detoxification of hydrogen peroxide, cellular responses to oxidative stress, heat, and iron ion starvation, as well as pigmentation, appressorium formation, host invasion, conidia formation, sporulation, hyphal growth, and homeostasis. Its product localizes to the ascospore wall, peroxisomal lumen, cytosol, and is linked to secretion. Related genes in other species are associated with oxidative stress response.
