Leaf senescence is influenced by endogenous developmental and external environmental signals. In this work, we found that expression of an Ap2/DREB-type transcription factor gene, Arabidopsis Rap2.4f (At4g28140), was upregulated by salt, mannitol, and dark treatments. Constitutively overexpressing Rap2.4f under the control of the CaMV 35S promoter led to an increased chlorophyll degradation rate and upregulation of many senescence-associated genes in the transgenic Arabidopsis lines. Our results show that Rap2.4f is a positive regulator of senescence, promoting both developmental and dark-induced leaf senescence.14aARABIDOPSIS THALIANA14aLEAF SENESCENCE14aAP214aRAP2.4F12aXu, H.12aWang, X.12aChen, J.40uhttps://drive.google.com/file/d/11D-NMbGloiEIpHDtVLQLO2Cw0WnBz8wi/view?usp=drivesdkzPara ver el documento ingresa a Google con tu cuenta: @cicy.edu.mx250602s9999    xx |||||s2   |||| ||und|d
