متن کاملCytotype stability, facultative apomixis and geographical parthenogenesis in Ranunculus kuepferi (Ranunculaceae)
BACKGROUND AND AIMS Asexual organisms are more widespread in previously glaciated areas than their sexual relatives ('geographical parthenogenesis'). In plants, this pattern is probably dependent on reproductive isolation and stability of cytotypes within their respective distribution areas. Both partial apomixis and introgressive hybridization potentially destabilize the spatial separation of ...
متن کاملPhylogenetic relationships in Ranunculus species (Ranunculaceae) based on nrDNA ITS and cpDNA trnL-F sequences
The genus Ranunculus L., with a worldwide distribution, is the largest member of the Ranunculaceae. Here, nuclear ribosomal internal transcribed spacer (ITS) sequence data and chloroplast trnLF sequence data were used to analyze phylogenetic relationships among members of the annual and perennial (Group Praemorsa, Group Rhizomatosa, Group Grumosa and Group non-Grumosa) species of Ranunculus...
متن کاملA new record and a synonym in the genus Ranunculus (Ranunculaceae) from Iran
In a project on the Flora of Iran (Trib.: Ranunculeae), many herbarium specimens of thegenus Ranunculus were studied. The results of this study are a new record and suggestion of a synonym for the Flora of Iran, specimens of which are preserved in the herbarium of Research Institute of Forest & Rangelands (TARI).
متن کاملDevelopment of EST-derived microsatellite markers in the aquatic macrophyte Ranunculus bungei (Ranunculaceae)1
PREMISE OF THE STUDY Microsatellite or simple sequence repeat (SSR) markers were developed to investigate the influence of ecological factors on gene flow and spatial genetic structuring of the submerged plant Ranunculus bungei (Ranunculaceae), which is regarded as an important species for understanding how plants adapt to an aquatic environment. METHODS AND RESULTS Twenty-two microsatellite ...
