Molecular divergence between North Atlantic and Indo-West Pacific Cladophora albida (Cladophorales: Chlorophyta) isolates as indicated by DNA-DNA hybridization
Genomic relationships between North Atlantic, Australian and Japanese isolates of the benthic seaweed Cladophora albida (Huds.) Kütz. were examined in 1987 by means of DNA-DNA hybridization. The data indicate that C. albida can be divided into a North Atlantic and an Indo-West Pacific group with an...
