- Abstract:
Deficiens is a floral homeotic gene of Antirrhinum majus, mutation of
which results in transformation of petals to sepals and stamens to
carpels. In a search for putative target genes, controlled by this
regulatory locus, cDNA clones representing genes, that are expressed in
wild type but not in the deficiens mutant flowers, were isolated by
differential screening. The molecular structure and the expression pattern
of one of these genes, tap2, is described. Tap2 is transiently and
tissue-specifically expressed in the tapetum of the anthers. It encodes a
131 amino-acids-long protein with a hydrophobic N-terminus, displaying all
characteristic features of a signal peptide. This indicates that the TAP2
protein may be secreted.
