RPS4 — Arabidopsis thaliana

Summary

ATCG00380 (RPS4) encodes the chloroplast ribosomal protein S4 (uS4C), a structural constituent of the ribosome that also binds mRNA. The gene is associated with translation, cell death, programmed cell death, the hypersensitive response, jasmonic acid anabolism, photorespiration, the pentose-phosphate shunt, quorum sensing, cell communication, protein targeting, secretion, virus-induced PTGS, cell growth, and the mitotic cell cycle. RPS4 localises to the plastid small ribosomal subunit and chloroplast stroma. RPS4 is associated with disease resistance in Arabidopsis, including resistance to bacterial wilt (Ralstonia solanacearum), bacterial blight, Colletotrichum higginsianum, and Pseudomonas syringae, as well as immune response autoactivity and resistance to the effectors AvrRps4 and PopP2. Related genes in other species are associated with resistance to Pseudomonas syringae pv. tomato.
