Elymus species; Evolution; ITS sequence; Phylogeny; Poaceae; trnL-F sequence

Elymus L. is often planted in temperate and subtropical regions as forage. Species in the genus have 5 allopolyploid genomes that are found in the grass tribe Triticeae. To determine the phylogenetic relationships in Elymus species from western China, we estimated phylogenetic trees using sequences from the nuclear ribosomal internal transcribed spacer and non-coding chloroplast ... more

Bayesian analysis; Phylogeny; Species group; Streptococcus

Alternative phylogenies for the genus Streptococcus have been proposed due to uncertainty about the among-species group relationships. Here, we performed a phylogenetic analysis of the genus Streptococcus, considering all the species groups and also the genomic data accumulated by other studies. Seventy-five species were subjected to a Bayesian phylogenetic analysis ... more

Biological evolution; Gossypium raimondii; Phylogeny; Sequence analysis; Synteny; TIFY gene family

The highly conserved TIFY domain is included in the TIFY protein family of transcription factors, which is important in plant development. Here, 28 TIFY family genes were identified in the Gossypium raimondii genome and classified into JAZ (15 genes), ZML (8), PPD (3), and TIFY (2). The normal (TIF[F/Y]XG) motif was dominant in the TIFY ... more

morphology; Phylogeny; Salix matsudana; Species concept

The morphological species concept is based on morpho­logical traits, which are often subject to subjectivity or artifact. Molecular evidence is needed to test the reliability of morphological classification of taxa that are controversial and to provide appropriate taxonomic de­limitation. In this study, we used 15 single-copy nuclear loci and 2 chlo­roplast fragments to verify the ... more

Expression profile; GRAS; Jatropha curcas L.; Phylogeny; Physic nut

GRAS proteins play vital roles in plant growth and development. Physic nut (Jatropha curcas L.) was found to have a total of 48 GRAS family members (JcGRAS), 15 more than those found in Arabidopsis. The JcGRAS genes were divided into 12 subfamilies or 15 ancient monophyletic lineages based on the phylogenetic analysis of GRAS proteins from both flowering and ... more

Microbiome; Mitis group; Phylogeny; RecN; Streptococcus massiliensis

Streptococcus is a diverse bacterial lineage. Species of this genus occupy a myriad of environments inside humans and other animals. Despite the elucidation of several of these habitats, many remain to be identified. Here, we explore a methodological approach to reveal unknown bacterial environments. Specifically, we inferred the phylogeny of the Mitis group by analyzing the ... more

Chinese catfish; Intraspecific variation; Mitochondrial genome; Phylogeny; Southern catfish; Structure

The complete mitochondrial genome of the Southern catfish (Silurus meridionalis) and the Chinese catfish (S. asotus), was determined using the long and accurate polymerase chain reaction (LA-PCR) method. The mitochondrial DNA nucleotide sequences of S. meridionalis and S. asotus were compared with those of 47 other catfish species in the same order. The ... more

Bovine leukemia virus; Long terminal repeat; Phylogeny

We conducted a phylogenetic analysis of 22 strains of bovine leukemia virus obtained by polymerase chain reaction to amplify a 582-base pair fragment of the transcriptional regulatory region 5' long terminal repeat (LTR). Twenty-two samples of proviral DNA from peripheral blood mononuclear cells containing bovine leukemia virus from naturally infected bovine from 4 distinct geographic ... more

Function; Gene; Metabolism; Phylogeny; Synechococcus

Synechococcus sp PCC 7336 represents a newly sequenced strain, and its genome is obviously different from that of other Synechococcus strains. In this analysis, local alignment and annotation databases were constructed and combined with various bioinformatic tools to carry out gene annotation and functional analysis of this strain. From this analysis, we identified 5096 ... more

COI; Heteroptera; Mitochondrial DNA; Molecular systematics; Phylogeny

The mitochondrial cytochrome oxidase subunit 1 (COI) gene is one of the most popular markers used for molecular systematics. Fragments of this gene are often used to infer phylogenies, particularly the region near the 5'-end, which is used by the DNA Barcoding Consortium. With a growing number of sequences being deposited in the DNA barcoding database, there is an urgent need to ... more
