RT Journal Article SR Electronic A1 Krienitz, Lothar A1 Bock, Christina A1 Kotut, Kiplagat A1 Pröschold, Thomas T1 Genotypic diversity of Dictyosphaerium-morphospecies (Chlorellaceae, Trebouxiophyceae) in African inland waters, including the description of four new genera. JF Fottea YR 2012 VO 12 IS 2 SP 231 OP 253 DO 10.5507/fot.2012.017 UL https://fottea.czechphycology.cz/artkey/fot-201202-0006.php AB Trebouxiophytes of the Dictyosphaerium-morphotype from inland waters of Africa were studied using a polyphasic approach of SSU and ITS rDNA phylogeny, secondary structure of the ITS and observations made with a light microscope. Although the morphological criteria for differentiating species and genera are scarce, the genetic diversity of these algae was very high. Based on our genetic analysis findings, we described four new genera containing five new species: Compactochlorella dohrmannii, Compactochlorella kochii, Kalenjinia gelatinosa, Marasphaerium gattermannii and Masaia oloidia. Diversity and distribution of Chlorella-related colonial chlorophytes in the tropical and temperate zones were compared and discussed.
