Molecular and morphological delimitation and generic classification of the family Oocystaceae (Trebouxiophyceae, Chlorophyta)

Popis výsledku v původním jazyce

The family Oocystaceae (Chlorophyta) is a group of morphologically and ultrastructurally distinct green algae that constitute a well-supported clade in the class Trebouxiophyceae. Despite the family&apos;s clear delimitation, which is based on specific cell wall features, only a few members of the Oocystaceae have been examined using data other than morphological. In previous studies of Trebouxiophyceae, after the establishment of molecular phylogeny, the taxonomic status of the family was called into question. The genus Oocystis proved to be paraphyletic and some species were excluded from Oocystaceae, while a few other species were newly redefined as members of this family. We investigated 54 strains assigned to the Oocystaceae using morphological, ultrastructural and molecular data (SSU rRNA and rbcL genes) to clarify the monophyly of and diversity within Oocystaceae. Oonephris obesa and Nephrocytium agardhianum clustered within the Chlorophyceae and thus are no longer members of the Oocystaceae. On the other hand, we transferred the coenobial Willea vilhelmii to the Oocystaceae. Our findings combined with those of previous studies resulted in the most robust definition of the family to date. The division of the family into three subfamilies and five morphological clades was suggested. Taxonomical adjustments in the genera Neglectella, Oocystidium, Oocystis, and Ooplanctella were established based on congruent molecular and morphological data. We expect further taxonomical changes in the genera Crucigeniella, Eremosphaera, Franceia, Lagerheimia, Oocystis, and Willea in the future.
