Evolution and Expression Patterns of CYC/TB1 Genes in Anacyclus: Phylogenetic Insights for Floral Symmetry Genes in Asteraceae
Homologs of the CYC/TB1 gene family have been independently recruited many times across the eudicots to control aspects of floral symmetry The family Asteraceae exhibits the largest known diversification in this gene paralog family accompanied by a parallel morphological floral richness in its specialized head-like inflorescence. In Asteraceae, whether or not CYC/TB1 gene floral symmetry functi...
متن کامل15-P013 Inheritance and molecular genetics of floral symmetry in Darwin’s Gloxinia peloria (Sinningia speciosa)
a massive sequencing approach of a cDNA library, the whole set of Hox genes of the chondrichthyan, Scyliorhinus canicula. We have sequenced seven BAC clones that include all of the HoxA, HoxB and HoxD clusters. The transcriptomic data suggests that no HoxC genes have been maintained in this species. The expression of the posterior Hox genes was studied by insitu hybridization and showed that al...
متن کاملFlowering time control in ornamental gloxinia (Sinningia speciosa) by manipulation of miR159 expression.
BACKGROUND AND AIMS Gloxinia (Sinningia speciosa) is a popular commercial plant for its attractive and colourful flowers. However, the genetic mechanism of flowering time regulation in gloxinia is largely unknown. Recent studies on model plants have elucidated that miR159 acts as a negative regulator of floral transition in short-day photoperiods. The aim of this study was to investigate whethe...
متن کاملFloral zygomorphy, the recurring evolution of a successful trait.
The flowers of the primitive angiosperm plants were radially symmetrical (actinomorphic). Flowers with bilateral symmetry (zygomorphic) evolved in several clades independently as an adaptation to specialized methods of pollination and played an important role in the diversification of flowering plants. In the model species Antirrhinum majus (snapdragon), the related genes CYCLOIDEA (CYC) and DI...
متن کاملChanges in expression pattern of the teosinte branched1-like genes in the Zingiberales provide a mechanism for evolutionary shifts in symmetry across the order.
PREMISE OF THE STUDY Floral symmetry is a trait of key importance when considering floral diversification because it is thought to play a significant role in plant-pollinator interactions. The CYCLOIDEA/TEOSINTE BRANCHED1 (CYC/TB1)-like genes have been implicated in the development and evolution of floral symmetry in numerous lineages. We thus chose to investigate a possible role for these gene...
