Interpretive Summary: The review discusses findings in maize inflorescence development and presents the results in the context of comparisons ot Arabidopsis.

Technical Abstract: One of the key events in plant development is the initiation of lateral organs from the flanks of the meristem. In grasses, the inflorescence meristem (IM) reiteratively initiates a series of lateral meristems with slightly different fates. Our understanding of the genes and networks that regulate grass inflorescence architecture has dramatically expanded due to significant advances in resources and tools. Many of the modules that regulate meristem fate in Arabidopsis (Arabidopsis thaliana) are also present in the grasses. Genetic networks that regulate IM size and floral organ fate are partially conserved between Arabidopsis and grasses, whereas genetic networks that regulate grass-specific meristems are either unique to grasses or have different functions in dicots.
