Review: Formal description of plant morphogenesis (J Exp Bot) ($)

In recent years, a number of tools have been developed to describe and model plant morphogenesis, and these approaches have greatly informed our understanding of the molecular processes that underpin the control of growth. This excellent review by Pałubicki et al. is “an attempt to bring together…
