Interpretive Summary: This review discusses recent work in understanding the regulation of organogenesis and in particular leaf formation, highlighting how regula- tory modules are often redeployed in different organ types and stages of development to achieve diverse forms through the balance of growth and differentiation.

Technical Abstract: Plant organs initiate from meristems and grow into diverse forms. After initiation, organs enter a morphological phase where they develop their shape, followed by differentiation into mature tissue. Investigations into these processes have revealed numerous factors necessary for proper development, including transcription factors such as the KNOTTED-LIKE HOMEOBOX (KNOX) genes, the hormone auxin, and miRNAs. Importantly, these factors have been shown to play a role in organogenesis in various diverse model species, revealing both deep conservation of regulatory strategies and evolutionary novelties that led to new plant forms. We review here recent work in understanding the regulation of organogenesis and in particular leaf formation, highlighting how regulatory modules are often redeployed in different organ types and stages of development to achieve diverse forms through the balance of growth and differentiation.
