PREMISE OF THE STUDY: The FOUR LIPS (FLP) and MYB88 transcription factors, which are closely related in structure and function, control the development of stomata, as well as entry into megasporogenesis in Arabidopsis thaliana . However, other locations where these transcription factors are expressed are poorly described. Documenting additional locations where these genes are expressed might define new functions for these genes. METHODS: Expression patterns were examined throughout vegetative and reproductive development. The expression from two transcriptional‐reporter fusions were visualized with either β‐glucuronidase (GUS) or green fluorescence protein (GFP). KEY RESULTS: Both flp and myb88 genes were expressed in many, previously unreported locations, consistent with the possibility of additional functions for FLP and MYB88 . Moreover, expression domains especially of FLP display sharp cutoffs or boundaries. CONCLUSIONS: In addition to stomatal and reproductive development, FLP and MYB88 , which are R2R3 MYB transcription factor genes, are expressed in many locations in cells, tissues, and organs.
