Abstract :This study aimed to investigate molecular taxonomic diversity of unicellular chlorophyte strains in the northern Anatolian freshwater habitats of Turkey. Five strains were isolated from various habitats i.e. salty lagoons, shallow lakes, or slow-flowing creeks. The habitats chosen were Cernek lagoon insert ignore into journalissuearticles values(Kızılırmak Delta, Samsun);, Kara lake insert ignore into journalissuearticles values(Çubuk, Ankara);, Sarıkum lagoon insert ignore into journalissuearticles values(Sinop);, and Sırakaraağaçlar creek insert ignore into journalissuearticles values(Sinop);. Although the observations based on light microscopy showed no significant differences in cell morphologies, phylogenetic analysis based on nucleotide sequences of nuclear 18S rDNA and chloroplast 16S rDNA regions suggested that our isolates are related to 3 chlorophyte species: Chlorella vulgaris Beijerinck insert ignore into journalissuearticles values(S705, S706, and S708);, C. sorokiniana Shihira & Kraus insert ignore into journalissuearticles values(A102);, and Heterochlorella luteoviridis insert ignore into journalissuearticles values(Chodat); J.Neustupa, Y.Nemcova, M.Eliás & PSkaloud insert ignore into journalissuearticles values(S705);. This study represents the first records of C. sorokiniana and H. luteoviridis species for the algal flora of Turkey.
