TATB — Pisum sativum

Summary

PSAT6G193680 (TATB, also known as HCF106) in garden pea (Pisum sativum) on chromosome 6LG2 encodes a TatA/B/E family protein with pH-dependent protein transporter activity and protein binding capability. The gene is associated with the twin-arginine translocation pathway, chloroplast thylakoid membrane protein import, upregulation of stomatal opening, regulation of reactive oxygen species anabolism, response to cold, and regulation of response to thirst. The product localises to the TAT protein transport complex, chloroplast thylakoid membrane, thylakoid, chloroplast envelope, and plastid. Observed associations include thylakoid membrane protein mobility and drought resistance. Studies of related genes in other species link the family to drought tolerance, photochemical quenching, root morphology traits, and elevated guard cell ROS with enhanced drought resistance.
