Strain survey on three continents confirms the polyphyly of the genus Pediastrum (Hydrodictyaceae, Chlorophyceae).

Year: 2014

Type: article

Abstract: Approximately 100 new strains of the Pediastrum-phenotype were isolated from inland waters of India, eastern and southwestern Africa, and Germany and were studied by light and scanning electron microscopy. The 18S rRNA and ITS genes of 28 strains were sequenced and compared with 25 sequences of Hydrodictyaceae from the GenBank database. Phylogenetic analyses confirmed the polyphyly of Pediastrum. The new species Sorastrum pediastriforme was described. This species resembled morphologically Pediastrum, however, the phylogenetic analyses revealed its affiliation within the genus Sorastrum. Furthermore, the following new combinations: Monactinus sturmii, Pseudopediastrum alternans, Pp. brevicorne, Pp. integrum, and Pp. pearsonii were established.
