An Analysis of the cup-shaped cotyledon Mutant
Mutations in CUCl and CUC2 (for NP-SHAPED COTYLEDON), which are newly identified genes of Arabidopsis, caused defects in the separation of cotyledons (embryonic organs), sepals, and stamens (floral organs) as well as in the formation of shoot apical meristems. These defects were most apparent in the double mutant. Phenotypes of the mutants suggest a common mechanism for separating adjacent orga...
متن کاملInsights from ANA-grade angiosperms into the early evolution of CUP-SHAPED COTYLEDON genes.
BACKGROUND AND AIMS The closely related NAC family genes NO APICAL MERISTEM (NAM) and CUP-SHAPED COTYLEDON3 (CUC3) regulate the formation of boundaries within and between plant organs. NAM is post-transcriptionally regulated by miR164, whereas CUC3 is not. To gain insight into the evolution of NAM and CUC3 in the angiosperms, we analysed orthologous genes in early-diverging ANA-grade angiosperm...
متن کاملGenes involved in organ separation in Arabidopsis: an analysis of the cup-shaped cotyledon mutant.
Mutations in CUC1 and CUC2 (for CUP-SHAPED COTYLEDON), which are newly identified genes of Arabidopsis, caused defects in the separation of cotyledons (embryonic organs), sepals, and stamens (floral organs) as well as in the formation of shoot apical meristems. These defects were most apparent in the double mutant. Phenotypes of the mutants suggest a common mechanism for separating adjacent org...
متن کاملEvolution and diverse roles of the CUP-SHAPED COTYLEDON genes in Arabidopsis leaf development.
CUP-SHAPED COTYLEDON2 (CUC2) and the interacting microRNA miR164 regulate leaf margin dissection. Here, we further investigate the evolution and the specific roles of the CUC1 to CUC3 genes during Arabidopsis thaliana leaf serration. We show that CUC2 is essential for dissecting the leaves of a wide range of lobed/serrated Arabidopsis lines. Inactivation of CUC3 leads to a partial suppression o...
متن کاملInteractions of CUP-SHAPED COTYLEDON and SPATULA Genes Control Carpel Margin Development in Arabidopsis thaliana
A characteristic feature of flowering plants is the fusion of carpels, which results in the formation of an enclosed gynoecium. In Arabidopsis thaliana, the gynoecium is formed by the fusion of two carpels along their margins, which also act as a meristematic site for the formation of internal structures such as ovules, the septum and transmitting tract. How gene interactions coordinate the fus...
