AT1G80490 — Arabidopsis thaliana

Summary

AT1G80490 (TPR1, TOPLESS-related 1) in Arabidopsis thaliana encodes a protein containing LisH, CTLH, and WD40 repeat domains, and is associated with histone methylase and demethylase activities, DNA-binding transcription repressor activity, and E2 protein ligase binding. TPR1 is linked to Fusarium wilt resistance, multicellular organism growth, regulation of developmental vegetative growth, simple leaf morphogenesis, fruit septum development, and cellular responses to salt and zinc. It localizes to the PRC2 complex, SWI-SNF complex, HDAC complex, and chromatin silencing complex. The gene is also associated with traits including freezing stress response, seed quality, tiller angle, stem strength, linoleic and linolenic acid content, plant female sterility, and in vitro regeneration ability. Related genes in other species are linked to plant stature, parthenocarpy, disease resistance, and soluble solid content.
