HSS — Arabidopsis thaliana

Summary

AT5G62000 (ARF2, also known as HSS, ORE14) encodes an auxin response factor containing B3 DNA-binding, AUX/IAA, and PB1-like domains, and has transcription corepressor activity, sequence-specific DNA binding, and protein heterodimerization activity. In Arabidopsis, ARF2 is associated with leaf longevity, developmental senescence, flavonol and proanthocyanidin accumulation, seed growth, organ growth, fruit dehiscence, differential growth, and negative regulation of transcription. It has been linked to traits including seed volume, seed weight, leaf area, inflorescence branching, harvest index, stem length, petal and sepal morphology, floral organ number, photoperiod-sensitive flowering time, and potassium sensitivity. The gene is also associated with auxin signalling, strigolactone signalling, shoot gravitropism, and sucrose transport pathways, and localizes to the nucleus, cytoplasm, and plasma membrane.
