Analysis of genetic relationships in germplasms of Mugua in China revealed by internal transcribed spacer and its taxonomic significance.

چکیده
Genetic relationships were studied among eight species of three taxa in the genus Chaenomeles by nuclear ribosomal internal transcribed spacer (ITS) analysis. A genetic distance matrix based on ITS sequences was estimated according to the formula of Kimura-2 parameter and a neighbour-joining phenogram, which were obtained with Clustalx4.1 software. The results showed that the germplasms of Mugua originate from Ch. speciosa (Sweet) Nakai, not including Ch. sinensis (Thouin) Kochne and Ch. cathayensis (Hemsl.) Schneid. The results also showed that 'Yao Mugua' and 'Ornamental Mugua' are the most distantly related species in germplasms.

This is the first study on phylogenetic relationships in the genus Artemia Leach, 1819 using the pattern and sequence of secondary structures of internal transcribed spacer 1 (ITS1). Significant intraspecific variation in the secondary structure of ITS1 rRNA was found in Artemia tibetiana. In the phylogenetic tree based on joined primary and secondary structure sequences, Artemia urmiana and pa...

متن کاملMolecular Identification of Rare Clinical Mycobacteria by Application of 16S-23S Spacer Region Sequencing
Objective(s) In addition to several molecular methods and in particular 16S rDNA analysis, the application of a more discriminatory genetic marker, i.e., 16S-23S internal transcribed spacer gene sequence has had a great impact on identification and classification of mycobacteria. In the current study we aimed to apply this sequencing power to conclusive identification of some Iranian clinical ...
متن کاملPhylogenetic relationships of anamorphic form of some Pleosporalean genera based on analysis of ITS rDNA and RPB2
Pleosporaceae is an important Dothideomycetes family. To elucidate relationships among some selected anamorphic pleosporalean taxa, their Internal Transcribed Spacer (ITS) and RNA polymerase second largest subunit (RPB2) were sequenced and compared. Phylogenetic analyses of both ITS and RPB2 regions were almost similar and generally congruent with previously described phylogenies and morphology...
