A Biosystematic Study of Silphium Integrifolium Michaux ( Compositae ) 1 - 2

Cytological and chromatographic data indicate that Silphium integrifolium Michx. is a rather homogeneous group of plants. Cytological study shows good pairing during meiosis in interspecific and intraspecific hybrids. Two-dimensional paper chromatography indicates that the varieties of S. integrifolium are more similar to each other than they are to two related species, S. asperrimum and 5. spe...

A REVISION OF PLANT-ASSOCIATED VERTICILLIUM SPECIES

Molecular approaches were used to re-evaluate the morphological criteria used to identify plant-associated Verticillium species. ITS-RFLPs divided the 31 studied strains of seven Verticillium species, (including the type species V. luteo-album) into four clusters. Cluster one comprised strains of the type species, V. luteo-album, cluster two V. albo-atrum, V. dahliae, V. nubilum and V. tricorpu...
