TIC20 — Pisum sativum

Summary

PSAT5G269960, designated PsTIC20-IV (also known as TIC20), encodes a protein. The gene is associated with protein import into the chloroplast stroma, protein secretion, the regulation of photosynthesis, and the downregulation of photosynthesis. It has been linked to chloroplast protein import, embryonic development, embryo viability, and gametophyte viability. The encoded product localises to the chloroplast inner membrane and has also been connected to mitochondria. Studies of related genes in other species, identified through sequence similarity, link the TIC20 family to photochemical quenching. In garden pea (Pisum sativum), this gene resides on chromosome 5LG3.
