    Robustness of floral organ numbers

    Despite the contribution of phenotypic variation in floral morphologies to speciation, species diversity has been recognized by modal morphologies where variation is averaged out. Here Kitazawa and Fujimoto show a relationship between the species-representative phenotype and phenotypic variation, by analysing quantitatively intraspecific variation of the organ numbers within flowers of Ranunculaceae and the numbers of […] More

  • Photos of flowers from plants of diverse orders with a simplified phylogeny above, sketching their relationships. From left to right: Nymphaea colorata (water lily, basal angiosperms); Lilium marthagon (lily, monocot); Triticum aestivum (bread wheat, monocot); Meconopsis horridula (prickly blue poppy, basal eudicot); Antirrhinum majus (snapdragon, fabid); Rosa sp. (rose, malvid)

    Tinkering with transcription factor networks for developmental robustness of Ranunculales flowers

    Species within the Ranunculales bear flowers of formidable variation; for example, one can find novel floral organs and loss of floral organs, zygomorphic and radially symmetric flowers, and variation in floral organ number. Becker reviews recent developments on the molecular aspects of Ranunculales flower development, focusing especially on aspects not found in Brassicaceae development, such […] More
