4 pages, 1 figure.CYCLOIDEA (CYC)-like TCP genes are critical for flower developmental patterning. Exciting recent breakthroughs, including a study by Song et al. published in BMC Evolutionary Biology, demonstrate that CYC-like genes have also had an important role in the evolution of flower form.LCH’s work is supported by NSF grant IOS-0616025.
