The gene encodes a putative transcription factor that regulates cell elongation in developing styles. The transition from cross-pollination to self-pollination was accompanied, not by a change in the STYLE2.1 protein, but rather by a mutation in the Style2.1 promoter that results in a down-regulation of Style2.1 expression during flower development. |
