Different Levels

The literature on sequencing as a tool for yeast molecular taxonomy is reviewed. Ribosomal DNA has been preferred for sequencing over other molecules such as mitochondrial DNA, and a large database is now available. rDNA consists of regions that evolve at different rates, allowing comparison of different levels of relationship among yeasts. Sequences of the 18S rDNA and the 25S rDNA have been largely used for yeast systematics and phylogeny, but the search for regions with increased resolving power has led to the study of the spacer regions of the rDNA. Few studies are concerned with signature sequences.Key words: yeast, molecular taxonomy, rDNA, sequencing.

Proclossiana Eunomia

The Proclossiana eunomia (Esper, 1799) complex is currently composed of the several subspecies distributed throughout Palaearсtic region and North America. Despite the fact that some of the taxa have differences in wing pattern and body size, previous assumptions on taxonomy not supported by molecular data. Therefore, the identity of certain populations of this complex has remained unclear and the taxonomic status of several recently described taxa is debated. Here, we provide insights into systematics of some Palaearctic members of this group using molecular approach, based on the analysis of the barcoding fragment of the COI gene taking into account known morphological differences.

18S Rdna Gene

The genus Hemiflagellochloris Watanabe et al. was found in Russia for the first time. The algal strain was isolated from a buried solonetz in the zone of dry steppes (the north-end of Ergeni Hills, Volgograd Region). The morphology and ecology of this isolate are described. Its phylogenetic position within Chlorophyceae is determined by molecular analysis of 18S rDNA gene.
