Abstract
A pattern formation of the floral organs is defined by the ABC model. In this well-known model, AGAMOUS (AG) protein, which is a C-function transcription factor, plays a role in specification of stamen and carpel. In the ag mutant of Arabidopsis thaliana, the stamen turns into the petal and the carpel is placed by another flower resulting to form double-flower.
Cyclamen classified in the family Primulaceae is one of major ornamental flowers in winter. For the modification of flower traits in shape of cyclamen, it is important to reveal the mechanism of morphogenesis of the flower organs. However, in cyclamen, there is no report on the genes encoding some proteins involved floral formation such as AG. Thus, we tried to isolate the AG genes in cyclamen and functional analysis of this gene. As the results, we found two kinds of AG transcription factors from cyclamen. We report here the details of the genes and the comparative studies on the expression patterns of these genes between organs and between mutants.
