Based on 16S rRNA phylogenetic analysis, the strain KPABG LID-610023 was placed in the clade of Inacoccus in spite of morphological and molecular differences from one already established species: Inacoccus carmineus. Morphologically the tested strain did not show colored hyaline envelopes, and nanocytes were absent. The nucleotide sequences of 16S rRNA gene clearly demonstrated a genetic difference, separating it from Inacoccus carmineus. In addition, we compared ITS sequences of KPABG LID-610023 strain and Inacoccus carmineus and found that nucleotide composition, length, and secondary structures of D1–D1' and Box-B were different. These results suggest that the strain KPABG LID-610023 appear to be a new species of the genus Inacoccus. Possibly this new species is a cryptic taxon due to its morphological similarity with Chroococcus pallidus Näg.","PeriodicalId":305989,"journal":{"name":"Issues of modern algology (Вопросы современной альгологии)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129243195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
