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...

The spatial context of reproduction is of crucial importance to plants because of their sessile habit. Since pollen and seed dispersal is often restricted, mating success is likely to depend on the quantity and quality of mates in local neighbourhoods. Here we use neighbourhood models to investigate the spatial ecology of pollination and mating in Narcissus assoanus, a sexually polymorphic plan...

Since L. Guignari's investigation (1884) various investigators have reported the studies on plants in the genus Allium of Liliaceae, as some species in this genus are cultivated and are noteworthy from the cytological point of view. According to T. Suto's papers (1936, 1936) on the phylogenetic discussion of Liliaceae and Amaryllidaceae, which show the fact that the idiogram type of the chromos...

Although chromoplasts and chloroplasts are mor­ phologically and functionally very different, it has been shown in certain plants and under certain con­ ditions, that they are interconvertible [see 1 5]. One could then expect such plastids to contain, at least qualitatively, the same plastome. It appears questionable, however, whether this applies to all plastid types. For example, FreyWyssling...
