Evolutionary maintenance of stigma-height dimorphism in Narcissus papyraceus (Amaryllidaceae).
Stigma-height dimorphism is a sexual polymorphism in which plant populations are composed of two floral morphs that differ significantly in style length but not anther position. The morphs exhibit approach and reverse herkogamy, floral designs that in most species typically occur as monomorphic conditions. We investigated the floral biology of stigma-height dimorphism in the Mediterranean geoph...
متن کاملMicrosatellite markers for hoop-petticoat daffodils (Narcissus sect. Bulbocodii; Amaryllidaceae).
PREMISE OF THE STUDY Microsatellite markers were developed using hoop-petticoat daffodils (Narcissus sect. Bulbocodii; Amaryllidaceae) to aid in the taxonomic revision of the section, and to further evaluate their broad applicability for daffodil cultivar identification. METHODS AND RESULTS Three hundred fifty-one primer pairs were developed using a commercial service. Nineteen polymorphic an...
متن کاملHerkogamy and mating patterns in the self-compatible daffodil Narcissus longispathus.
BACKGROUND AND AIMS Floral design in self-compatible plants can influence mating patterns. This study investigated Narcissus longispathus, a self-compatible bee-pollinated species with wide variation in anther-stigma separation (herkogamy), to determine the relationship between variation in this floral trait and the relative amounts of cross- and self-fertilization. METHODS Anther-stigma sepa...
متن کاملPhylogenetic reconstruction of the evolution of stylar polymorphisms in Narcissus (Amaryllidaceae).
We investigated the origin of stylar polymorphisms in Narcissus, which possesses a remarkable range of stylar conditions and diverse types of floral morphology and pollination biology. Reconstruction of evolutionary change was complicated by incomplete resolution of trees inferred from two rapidly evolving chloroplast regions, but we bracketed reconstructions expected on the fully resolved plas...
متن کاملPhenotypic integration in style dimorphic daffodils (Narcissus, Amaryllidaceae) with different pollinators.
Different pollinators can exert different selective pressures on floral traits, depending on how they fit with flowers, which should be reflected in the patterns of variation and covariation of traits. Surprisingly, empirical evidence in support of this view is scarce. Here, we have studied whether the variation observed in floral phenotypic integration and covariation of traits in Narcissus sp...
