We have isolated two flower-specific cDNA clones: clone 12 and clone 3405. Northern hybridization showed that the expression patterns of these genes differed from each other. The expression of transcripts corresponding to clone 12 peaked in 4-6mm buds and was not detected in the open flower, while the expression of transcripts corresponding to clone 3405 peaked in 8-10mm buds and decreased in the open flower. Analyses of the localization of their expression showed that clone 12 is specific to stamens in 10mm buds, while transcripts corresponding to 3405 are expressed in petals and pistils in 10mm buds only in pistils in the open flower. The expression patterns of these transcripts differed from those of previously reported floral homeotic genes.
