| 英文摘要 | The classic abc model explains the activities of each class of floral homeotic genes in specifying the identity of floral organs. thus, changes in these genes may underlay the origin of floral diversity during evolution. in this study, three mads-box genes were isolated from the perianthless basal angiosperm chloranthus spicatus. sequence and phylogenetic analyses revealed that they are ap1-like, ap3-like and sep3-like genes, and hence these genes were termed csap1, csap3 and cssep3, respectively. due to these assignments, they represent candidate class a, class b and class e genes, respectively. expression patterns suggest that the csap1, csap3 and cssep3 genes function during flower development of c. spicatus. csap1 is expressed broadly in the flower, which may reflect the ancestral function of squa-like genes in the specification of inflorescence and floral meristems rather than in patterning of the flower. csap3 is exclusively expressed in male floral organs, providing the evidence that ap3-like genes have ancestral function in differentiation between male and female reproductive organs. cssep3 expression is not detectable in spike meristems, but its mrna accumulates throughout the flower, supporting the view that sep-like genes have conserved expression pattern and function throughout angiosperm. studies of synonymous vs nonsynonymous nucleotide substitutions indicate that these genes have not evolved under changes in evolutionary forces. all the data above suggest that the genes may have maintained at least some ancestral functions despite the lack of perianth in the flowers of c. spicatus. |
