The TCP4 transcription factor of Arabidopsis blocks cell division in yeast at G1 → S transition

► TCP4 is a class II TCP transcription factor, that represses cell division in Arabidopsis. ► TCP4 expression in yeast retards cell division by blocking G1 → S transition. ► Genome-wide expression studies and Western analysis reveals stabilization of cell cycle inhibitor Sic1, as possible mechanism.
