Controlling meristematic activity is key determinant for reproductive development and plant growth. Here we document the role of a bZIP transcription factor, bZIP30, which we named DRINK ME, for the shrinking potion in ‘Alice in Wonderland’, in meristem control. Overexpression of DKM results in small plants with short fruits, whereas loss-of-function mutants have longer fruits, more floral buds and larger inflorescence meristems. Our results indicate that DKM is a modulator of meristematic activity and thus of reproductive development and plant growth.
