Dictyostelium Myb transcription factors function at culmination as activators of ancillary stalk differentiation.
ecmB and mrrA are expressed in the cups that cradle Dictyostelium spore heads, and MybE is necessary for their expression in lower but not upper cup cells. A Myb site within the mrrA promoter is necessary for expression in both cups. Thus, multiple Myb proteins are required for ancillary stalk differentiation.
