GYM — Arabidopsis thaliana

Summary

AT2G25170, also known as GYM, PKL, or CHD3 in Arabidopsis thaliana, encodes a CHD3-type chromatin-remodeling factor with DNA helicase and ATP hydrolase activities, and is associated with RNA polymerase II-specific DNA-binding transcription factor activity. This nuclear protein is associated with diverse biological processes including thermomorphogenesis, photoperiodism, vegetative phase change, cell fate determination, embryonic organogenesis, and regulation of lateral root development. The gene has been linked to numerous agronomically relevant traits such as seed yield, seed longevity, osmotic adjustment capacity, chilling and cold tolerance, salt stress tolerance, drought tolerance, cadmium and iron concentrations, phosphorus uptake, and responses to light quality including blue, red, and UV light sensitivity. Related genes in other species link the family to cytokinin content.
