Abstract
The spatially and temporally distinct expression of R2R3-MYB positive regulators is among the major mechanisms that create various anthocyanin color patterns in many flowers. However, we do not know how these positive regulators have gained different expression profiles. In the Asiatic hybrid lily ‘Lollypop’ (derived from the crosses of species belonging to Sinomartagon/Daurolirion section), MYB12 and MYB19S regulate the pigmentation at whole tepals and raised tepal spots, respectively. In the Oriental hybrid lily ‘Sorbonne’ (derived from the crosses of species belonging to the Archelirion section), MYB12 regulates both whole tepal and raised spot pigmentation. The genes have similar amino acid sequences with similar protein functions but exhibit different expression profiles in lily flowers. As promoters are among the most significant factors affecting gene expression profiles, their promoter sequences were determined in this study. The three genes had very different promoter sequences, and putative cis-regulatory elements were not conserved in numbers or order. To further confirm the promoter functions, tobacco plants were transformed with native promoter-driven MYB12 or MYB19S genes of ‘Lollypop.’ Expression levels of MYB12 were higher in corolla tubes than in lobes, while those of MYB19S were higher in corolla lobes than in tubes. Thus, the diverse promoter functions were likely to be the leading causes of their different expression profiles and generation of unique color patterns. Finally, the history of R2R3-MYB gene establishment during lily evolution was estimated using sequence data.
