Toward Modern Classification of Eustigmatophytes, Including the Description of Neomonodaceae Fam. Nov. and Three New Genera

Popis výsledku v původním jazyce

The class Eustigmatophyceae includes mostlycoccoid, freshwater algae, although some genera arecommon in terrestrial habitats and two are primarilymarine. The formal classification of the class,developed decades ago, does not fit the diversity andphylogeny of the group as presently known and is inurgent need of revision. This study concerns a cladeinformally known as the Pseudellipsoidion group of theorder Eustigmatales, which was initially known tocomprise seven strains with oval to ellipsoidal cells,some bearing a stipe. We examined those strains aswell as 10 new ones and obtained 18S rDNA and rbcLgene sequences. The results from phylogeneticanalyses of the sequence data were integrated withmorphological data of vegetative and motile cells.Monophyly of the Pseudellipsoidion group is supportedin both 18S rDNA and rbcL trees. The group isformalized as the new family Neomonodace aecomprising, in addition to Pseudellipsoidion, threenewly erected genera. By establishing Neomonodusgen. nov. (with type species Neomonodus ovalis comb.nov.), we finally resolve the intricate taxonomichistory of a species originally described as Monodusovalis and later moved to the genera Characiopsis andPseudocharaciopsis. Characiopsiella gen. nov. (with thetype species Characio psiella minima comb. nov.) andMunda gen. nov. (with the type species Mundaaquilonaris) are established to accommodateadditional representatives of the polyphyletic genusCharaciopsis. A morphological feature common to allexamined Neomonodaceae is the absence of apyrenoid in the chloroplasts, which discriminates themfrom other morphologically similar yet unrelatedeustigmatophytes (including other Characiopsis-likespecies).
