The homologs "GLOBOSA" and "DEFICIENS" have also been isolated and characterized in "Agapanthus praecox" ssp. "orientalis" (Agapanthaceae), which is phylogenetically distant from the model organisms. In this study the genes were called "ApGLO" and "ApDEF", respectively. Both contain open reading frames that code for proteins with 210 to 214 amino acids. Phylogenetic analysis of these sequences indicated that they belong to B gene family of the monocotyledons. In situ hybridization studies revealed that both sequences are expressed in verticil 1 as well as in 2 and 3. When taken together, these observations show that the floral development mechanism of "Agapanthus" also follows the modified ABC model.
