SRG3 — Arabidopsis thaliana

Summary

AT5G59820 (SRG3, also known as ZAT12 and RHL41) encodes a C2H2-type zinc finger transcription factor that localises to the nucleus and binds DNA and zinc. In Arabidopsis thaliana, this gene is associated with tolerance to high salinity, high-intensity light, freezing, heat, and superoxide stress, as well as with senescence, chlorophyll content, and aphid response. It is associated with the regulation of photosynthesis, jasmonic acid signalling, root development, and cold acclimation, and with processes including oxygen metabolism, detoxification, calcium signalling, and response to chitin and drought. Associations also extend to traits such as iron and calcium concentration, leaf thickness and morphology, root length, seed maturation, anthocyanin content, and stem senescence. Studies of related genes in other species link the family to chilling stress tolerance and defence responses.
