Natural variation in OsMYB305 downregulating cytokinin-mediated inhibition of leaf senescence contributes to regional adaptation in rice.

Abstract excerpt

Accumulating evidence has identified transcription factors (TFs) as key regulators of the onset and progression of leaf senescence. However, the regulatory role of the rice myeloblastosis (MYB) TF OsMYB305 in this process remains largely unknown. CRISPR/Cas9-mediated osmyb305 knockout mutants were used to examine senescence phenotypes. Protein-DNA interactions were analyzed using in vivo and in vitro binding...
