ATH3 — Cucumis sativus

Summary

CsATH3 (ATH3) on cucumber chromosome 2 encodes a thioredoxin domain-containing protein with oxidoreductase activity acting on a sulfur group of donors, disulfide as acceptor, and protein-disulfide reductase activity. It is associated with sex determination, chlorophyll metabolism, regulation of systemic acquired resistance, defence responses to bacteria and insects, and response to microbial phytotoxin. The gene has been connected to numerous agronomic traits including cucurbit downy mildew response, bacterial blight disease resistance, drought sensitivity, photosynthetic rate, stomatal closure time, leaf senescence, and sugar content. It is linked to phenotypes such as immunity, herbivory resistance, salt tolerance, thermotolerance, cold tolerance, and systemic acquired resistance. The protein localises to the nuclear body, chloroplast stroma, ER, plasmodesma, and plant-type cell wall.
