|a PISTILLATA (PI) plays crucial roles in Arabidopsis flower development by specifying petal and stamen identities. To investigate the molecular mechanisms underlying organ development of woody angiosperm in Catalpa, we isolated and identified a PI homologue, referred to as CabuPI (C. bungei PISTILLATA), from two genetically cognate C. bungei (Bignoniaceae) bearing single and double flowers. Sequence and phylogenetic analyses revealed that the gene is closest related to the eudicot PI homologues. Moreover, a highly conserved PI-motif is found in the C-terminal regions of CabuPI. Semi-quantitative and quantitative real time PCR analyses showed that the expression of CabuPI was restricted to petals and stamens. However, CabuPI expression in the petals and stamens persisted throughout all floral development stages, but the expression levels were different. In 35S::CabuPI transgenic homozygous pi-1 mutant Arabidopsis, the second and the third whorl floral organs produced normal petals and a different number of stamens, respectively. Furthermore, ectopic expression of the CabuPI in transgenic wild-type or heterozygote pi-1 mutant Arabidopsis caused the first whorl sepal partially converted into a petal-like structure. These results clearly reveal the functional conservation of PI homologues between C. bungei and Arabidopsis
