Salvia siirtica sp. nov. (Lamiaceae) from Turkey

Salvia siirtica Kahraman, Celep & Do?an sp. nov.(Lamiaceae) is described and illustrated as a new species from the northern part of Siirt province in southeast Anatolia, Turkey, where it was found growing in open forests of Quercus. It is morphologically similar to S. indica L., but differs by having densely glandular pilose to villous stems and petioles, close verticillasters, smaller flowers, clearly concave calyx apices, entirely white corollas and smaller nutlets. Salvia siirtica and S. indica are also distinguished by their nutlet and pollen micromorphologies, illustrated by SEM images. The nutlet surface of S. siirtica is very finely wrinkled and its pollen has 3–4 primary lumina per 25 μm², compared to 5–8 in S. indica. Conservation status assessment, distribution map, and notes on biogeography and ecology of the new species are provided.     

Streptosporangium anatoliense sp. nov., isolated from soil in Turkey

A novel actinobacterium, strain N9999^T, was isolated from soil and its taxonomic position determined using a polyphasic approach. The organism formed abundant aerial hyphae that differentiated into spherical spore vesicles. The cell wall contained meso-diaminopimelic acid; the whole-cell sugars were galactose, glucose, mannose, madurose and ribose; the predominant menaquinones MK-9 (H₂) and MK-9 (H₄); the major phospholipids phosphatidylethanolamine, diphosphatidylglycerol, a phosphaglycolipid and phosphatidylinositol mannosides; while the cellular fatty acids were rich in iso-C_14:0, C_15:0, cis-9-C_17:1, iso-C_16:0 and 10-methyl C_17:0 components. Phylogenetic analyses based on an almost complete 16S rRNA gene sequence indicated that strain N9999^T was closely related to a group that consisted of Streptosporangium pseudovulgare DSM 43181^T and Streptosporangium nondiastaticum DSM 43848^T. However, DNA–DNA relatedness and phenotypic data demonstrated that strain N9999^T was clearly distinguished from all closely related Streptosporangium species. The combined genotypic and phenotypic data demonstrate conclusively that the isolate should be classified as a new species of Streptosporangium.     

Pseudomonas sivasensis sp. nov. isolated from farm fisheries in Turkey

A study of 91 isolates from fish farms in Turkey showed that isolates P7^T, P11, P24b, P29, P72, P73 and P158 belonged to the genus Pseudomonas according to 16S rRNA nucleotide sequence analysis. The analysis of the sequences of the RNA polymerase sigma factor gene (rpoD) located these strains in the Pseudomonas fluorescens lineage of species within the P. fluorescens subgroup, close to the cluster composed of the species Pseudomonas grimontii, Pseudomonas marginalis and Pseudomonas panacis. Based on similarities in the 16S rRNA and rpoD gene sequences of three previously isolated strains from other origins (CCUG 57209, CCUG 62357 and W5.2-93) linked them to the same cluster. A polyphasic taxonomic approach including phenotypic characterization, fatty acid composition, and multilocus sequence analysis, together with whole-cell MALDI-TOF data, corroborated this assumption. The genome G+C mol% contents were 59.48 and 59.71, respectively. The average nucleotide indices based on BLAST analysis and the genome-to-genome distance calculation for the P7^T and CCUG 57209 strains with their closest relative, P. grimontii, were 88.16–88.29% and 38.10–38.20%, respectively. These data confirm that isolates P7^T, P11, P24b, P29, P72, P73, P158, CCUG 57209, CCUG 62357 and W5.2-93 represent a new species for which the name Pseudomonas sivasensis is proposed, with P7^T as a type strain (=CCUG 74260^T= and CECT30107^T).     

Polygonum istanbulicum Keskin sp. nov. (Polygonaceae) from Turkey

Chaenorhinum semispeluncarum sp. nov. and C. yildirimlii sp. nov. (Scrophulariaceae) from east Anatolia,Turkey

Chaenorhinum semispeluncarum H. Y?ld?r?m, Kit Tan, S. ?enol & A. Pirhan sp. nov. and C. yildirimlii Kit Tan, H. Y?ld?r?m, S. ?enol & A. Pirhan sp. nov. (Scrophulariaceae, C. sect. Microrrhinum) from east Anatolia are described and illustrated. They are both narrow endemics related to the rare C. cryptarum, also from east Anatolia. Chaenorhinum semispeluncarum occurs on calcareous marl rich in potassium nitrate at the entrance of wet caves in Malatya and differs from C. cryptarum by its erect habit, smaller corollas, shallowly ribbed and tuberculate, bicoloured seeds. Chaenorhinum yildirimlii from the neighbouring province of Erzincan was found on alluvial soil of stream banks and differs from C. semispeluncarum by its seed characters which are similar to those of C. cryptarum. Chaenorhinum yildirimlii differs from C. cryptarum, most conspicuously by the violet lower corolla lip spotted dark purple at the apex.     

Persicaria changhuaensis sp. nov. (Polygonaceae) from northwestern Zhejiang,China

Persicaria changhuaensis sp. nov., belonging to P. sect. Echinocaulon (Polygonaceae), from Zhejiang, eastern China, is described and illustrated. The new species is morphologically similar to P. senticosa (Meisn.) H. Gross ex Nakai and P. sagittata (L.) H. Gross ex Nakai var. sieboldii (Meisn.) Nakai, but differs from the former in having an ocrea without a reniform‐orbicular wing at apex, pubescent peduncle, triangular bracteoles, white perianth, and stamens exserted from the perianth. Compared to P. sagittata var. sieboldii, it differs in having the leaf blade triangular‐hastate, sparsely retrorsely‐prickled on abaxial veins, sparsely ciliate at the margin, pubescent peduncle, triangular bracteoles, and stamens exserted from the perianth.

Genomic insight into Chryseobacterium turcicum sp. nov. and Chryseobacterium muglaense sp. nov. isolated from farmed rainbow trout in Turkey

Four strains, designated as C-2, C-17^T, C-39^T and Ch-15, were isolated from farmed rainbow trout samples showing clinical signs during an investigation for a fish-health screening study. The pairwise 16S rRNA gene sequence analysis showed that strain C-17^T shared the highest identity level of 98.1 % with the type strain of Chryseobacterium piscium LMG 23089^T while strains C-2, C-39^T and Ch-15 were closely related to Chryseobacterium balustinum DSM 16775^T with an identity level of 99.3 %. A polyphasic approach involving phenotypic, chemotaxonomic and genome-based analyses was employed to determine the taxonomic provenance of the strains. The overall genome relatedness indices including dDDH and ANI analyses confirmed that strains C-2, C-17^T, C-39^T and Ch-15 formed two novel species within the genus Chryseobacterium. Chemotaxonomic analyses showed that strains C-17^T and C-39^T have typical characteristics of the genus Chryseobacterium by having phosphatidylethanolamine in their polar lipid profile, MK-6 as only isoprenoid quinone and the presence of iso-C_15:0 as major fatty acid. The genome size and G + C content of the strains ranged between 4.4 and 5.0 Mb and 33.5 – 33.6 %, respectively. Comprehensive genome analyses revealed that the strains have antimicrobial resistance genes, prophages and horizontally acquired genes in addition to secondary metabolite-coding gene clusters. In conclusion, based on the polyphasic analyses conducted on the present study, strains C-17^T and C-39^T are representatives of two novel species within the genus Chryseobacterium, for which the names Chryseobacterium turcicum sp. nov. and Chryseobacterium muglaense sp. nov. with the type strains C-17^T (=JCM 34190^T = KCTC 82250^T) and C-39^T (=JCM 34191^T = KCTC 822251^T), respectively, are proposed.
