Cytological and Molecular Characterization of Intertribal Hybrids between the Geophytes Anemone coronaria L. and Ranunculus asiaticus L. (Ranunculaceae)
Anemone coronaria L. and Ranunculus asiaticus L. both belong to the Ranunculaceae, a large plant family with many ornamentals of horticultural importance. There are considerable differences between these species leaves, flower morphology and flower colour therefore intergeneric crosses between the species might result in new interesting hybrids. Crosses between Anemone coronaria L. and Ranuncul...
متن کاملOut of the Alps: colonization of Northern Europe by East Alpine populations of the Glacier Buttercup Ranunculus glacialis L. (Ranunculaceae).
Ranunculus glacialis ssp. glacialis is an arctic-alpine plant growing in central and southern European and Scandinavian mountain ranges and the European Arctic. In order to elucidate the taxon's migration history, we applied amplified fragment length polymorphism (AFLP) to populations from the Pyrenees, Tatra mountains and Northern Europe and included data from a previous study on Alpine access...
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 ...
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 کاملبررسی پولک نکتاری (Nectar) در گونههای یکساله جنس آلاله (Ranunculus) از تیره آلاله (Ranunculaceae) در ایران
Ranunculus L. یکی از بزرگترین جنسیهای تیره Ranunculaceae با 600 گونه است. به دلیل وجود تنوع ریختی در بین افراد و جمعیتهای یک گونه و پلی مورفیسم در صفات، تاکسونومی این جنس همیشه با مشکلاتی همراه بوده است. با توجه به با ارزش شناخته شدن صفات نکتاری در مطالعات پیشین، در این پژوهش سعی شد تا این گروه از صفات در گونههای یکساله آلاله بررسی شوند. نمونههای مورد استفاده به صورت هرباریومی در اختیار قر...
