Research Abstract

In this study, expression analyses of cell cycle regulators were performed to elucidate the mechanisms underlying auxin-mediated cell cycle regulation. We found that the level of B2-type cyclin-dependent kinase (CDKB2), a major regulator of plant cell cycle progression, is tightly controlled by multiple pathways to maintain the meristem size in developing roots.
