Abstract
Leaves of higher plants develop in a sequential manner from the shoot apical meristem. Previously it was determined that perturbed leaf development in maize rough sheath2 (rs2) mutant plants results from ectopic expression ofknotted1-like (knox) homeobox genes. Here, thers2 gene sequence was found to be similar to theAntirrhinum PHANTASTICA (PHAN) gene sequence, which encodes a Myb-like transcription factor. RS2 and PHAN are both required to prevent the accumulation of knox gene products in maize and Antirrhinum leaves, respectively. However,rs2 and phan mutant phenotypes differ, highlighting fundamental differences in monocot and dicot leaf development programs.Keywords
