Description of two new species of Nostoc from China based on the polyphasic approach

The present study described two new Nostoc species, favosum (CHAB5709, CHAB5713, and CHAB5714) mirabile (CHAB5756 CHAB5784) based on the polyphasic approach combining morphological, genetic ecological characteristics. Five investigated strains were found to possess morphological features of genus. Results showed that 16S rRNA gene sequences these five displayed ≥ 95%, ≤ 98% similarity genus Nostoc. phylogenetic analysis inferred using bayesian inference, maximum-likelihood neighbour-joining methods placed separate nodes away from other species. 16S-23S internal transcribed spacer (ITS) secondary structure species a unique pattern D1-D1', Box-B V3 helix, which distinguished them And further established by percent dissimilarity ITS between another
