Watanabea acidotolerans: A new trebouxiophyte lineage (Chlorophyta) inhabiting low pH environments from Europe to South America

Original language description

Here we studied a new Watanabea strain CAUP H 8901-CRYO isolated from an extremely acidic (pH 2.6) pit lake in Czechia. We used morphological, ultrastructural and molecular data to ascertain its taxonomic position and phylogenetic relationships within the genus Watanabea. The morphology of the studied strain matched the formal Watanabea description, including its most characteristic feature, the production of two types of autospores. The new isolate morphologically and ultrastructurally resembled the Watanabea type species, W. reniformis. However, it differed from W. borysthenica by having a pyrenoid not surrounded by starch grains. Molecular phylogenetic analyses of nuclear 18S rDNA and plastid rbcL showed that the strain CAUP H 8901-CRYO formed an independent lineage within the genus Watanabea. Furthermore, analyses of nuclear ITS2 secondary structure demonstrated an additional side loop coiling from the helix III, the unique feature of CAUP H 8901-CRYO, not present in the authentic strain of W. reniformis SAG 211-9b. The ITS2 secondary structures of the two strains also differed by one compensatory base change (CBC) and a number of additional nucleotide substitutions. The new acidotolerant strain and another Watanabea isolate from a naturally acidic lake in Argentina were identical in their plastid rbcL sequence. Consequently, here we proposed a new species, Watanabea acidotolerans, to accommodate a lineage of microalgae with a possible worldwide distribution and tolerance to low pH habitats.
