OMA1 — Beta vulgaris subsp. vulgaris

Summary

BvOMA1 (BVRB_3G067450) on sugar beet chromosome Bvchr3_un.sca003 encodes a protein with peptidase M48 and Mito/Outer_Membr_Metalloprot domains, and is annotated with protease and metalloendopeptidase activity and metal binding. The gene is associated with homologous recombination, meiosis, cellular response to heat, anther development, response to oxidative stress, and osmotic response. Its product localises to the membrane and mitochondria. BvOMA1 is linked to cytoplasmic male sterility and decreased tolerance to multiple stressors. Studies of related genes in other species connect the family to heat stress tolerance, OXPHOS system function, and root growth, while sequence similarity links the family to high temperature stress response and root thickness.
