PRE — Sorghum bicolor

Summary

SORBI_3003G254300, designated SbPRE, encodes a PRX5-like protein with thioredoxin and redoxin domains that exhibits thioredoxin peroxidase (TPx) activity (EC 1.11.1.25) and peroxidase activity, along with ATP hydrolase and protein-binding capabilities. This sorghum chromosome 3 gene is associated with cell redox homeostasis, hydrogen peroxide catabolism, and cellular responses to oxidative stress. It is linked to diverse developmental processes including meristem growth and structural organization, root cap development, root morphogenesis, lateral root formation, phyllome and leaf morphogenesis, inflorescence development, seedling development, and both male and female gamete generation. The encoded protein localizes to multiple cellular compartments including mitochondria, plastids, thylakoids, chloroplast envelope and stroma, cytosol, and the proteasome. Associations with agronomically relevant traits include drought tolerance, disease tolerance, herbicide sensitivity, zinc sensitivity, and various plant growth and development traits.
