APG6 — Solanum lycopersicum

Summary

SlAPG6 (SOLYC02G088610.4) on tomato chromosome 2 encodes a ClpB chaperonin family protein with ATP-dependent peptidase activity and protein folding chaperone function. It is associated with the Tic complex, plastid stroma, chloroplast inner membrane, thylakoid, and chloroplast envelope. The gene has been linked to carotenoid breakdown, protein unfolding, cellular protein complex assembly, protein metabolism, and regulation of hormone levels. Associations include photosynthetic ability, biomass yield, fruit firmness, seed longevity, leaf angle, root weight, and fruit position. It is also linked to chloroplast development, thylakoid membrane biogenesis, heat stress response, thermotolerance, and abiotic stress tolerance. Studies of related genes in other species link the family to chloroplastic homeostasis, protein translocation, and chloroplast protein import.
