| 摘要_英文 | two fungal strains (k-2(t) and s1) were isolated from the deepest ocean sediment of the challenger deep located in the mariana trench. the internal transcribed spacer (its) gene sequences of the isolates k-2(t) and s1 differed from those of closely related species, such as talaromyces assiutensis and t. trachyspermus. phylogenetic analyses based on single and concatenated alignments of the genes, namely its, beta-tubulin (bena), calmodulin (cam), and the second-largest subunit fragment of the rna polymerase ii (rpb2) showed that the isolates k-2(t) and s1 were clustered together with other talaromyces species, such as t. trachyspermus and t. assiutensis, as evidenced by the position on a terminal branch with high bootstrap support. they could also be distinguished from their closest relatives with valid published names via morphological and physiological characteristics, for example, growth at 4 c-degrees-50 c-degrees with a ph in the range of 1.5-12. based on their phylogenetic, morphological, and physicochemical properties, the isolates k-2(t) and s1 represent a novel species in the genus talaromyces, and the proposed name is talaromyces sedimenticola sp. nov. the type strain is k-2(t) (= gdmcc 3.746(t) = jcm 39451(t)). |
