RPS4 — Arabidopsis thaliana

Summary

ATMG00290, also known as RPS4 or uS4M, encodes a mitochondrial ribosomal protein S4 that is a structural constituent of the ribosome and is localized to the mitochondria and the mitochondrial ribosomal small subunit. In Arabidopsis thaliana, RPS4 is associated with bacterial wilt resistance, pathogen immunity, and the immune response, as well as programmed cell death, shade avoidance, ethylene anabolism, ABA signaling, and virus-induced PTGS. The gene is linked to disease tolerance, resistance to Ralstonia solanacearum and Colletotrichum higginsianum, and mitochondrial protein synthesis. Studies of related genes in other species connect the family to cell death in tobacco and disease resistance, including resistance to Pseudomonas syringae, in tomato, as well as fungal resistance in cucumber.
