• Petal, sepal, or tepal? B-genes and monocot flowers

      Dodsworth, Steven; Royal Botanic Gardens, Kew (Elsevier Ltd, 2016-11-25)
      In petaloid monocots expansion of B-gene expression into whorl 1 of the flower results in two whorls of petaloid organs (tepals), as opposed to sepals in whorl 1 of typical eudicot flowers. Recently, new gene-silencing technologies have provided the first functional data to support this, in the genus Tricyrtis (Liliaceae).
