TIC32 — Daucus carota subsp. sativus

Summary

DCAR_011743, symbol TIC32 (DcTIC32) on carrot chromosome 3, encodes a short-chain dehydrogenase/reductase family protein with protochlorophyllide reductase activity, calmodulin and calcium ion binding, and redox activity. It is associated with chloroplast inner membrane and thylakoid membrane localisation, the TIC complex, and processes including chloroplast protein import, chlorophyll biosynthesis, calcium ion detection, mechanical stimulus response, and protein transport. The gene has been connected to plastid and chloroplast development, seed viability, leaf senescence, flowering time, stomatal closure, abscisic acid sensitivity, jasmonic acid content, and salt tolerance. Related genes in other species link the family to embryo lethality, chloroplast biogenesis, and protein import into chloroplasts.
