Elymus species; Epichloë endophyte; Hordeum species; Host specificity; Maternal donor; Phylogeny

Epichloë endophytes are widely distributed mutualists of cool-season grasses and can protect their hosts against biotic and abiotic stresses. Previous studies have shown that Epichloë endophytes are specific to their grass hosts in tall Festuca and Lolium species. However, no systematic analysis exists of host specificity of asexual Epichloë ... 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

Chloroplast genome; Complete sequences; Morus atropurpurea; Morus multicaulis; Phylogeny

The complete chloroplast genome (cpDNA) sequences of two cultivated species of Morus L. (Morus atropurpurea and Morus multicaulis) are reported and reconstructed in this study, and were compared with that of wild Morus mongolica. In M. atropurpurea, the circular genome is 159,113 bp in size and comprises two identical ... more

cpDNA rpL16 intron; cpDNA rps16 exon; nrDNA ITS; Phylogeny; Pimpinella; Umbelliferae

Pimpinella L. is a large genus and arguably one of the most complex genera in the family Apiaceae. In this study, the infra-generic relationship between Southwest Asian Pimpinella species and their generic allies in the tribe Pimpinelleae Spreng were investigated using sequence data from the cpDNA (chloroplast DNA) rps16 exon and ... more

Four Hyriopsis cumingii populations, a breeding population (BP), a cultured population (FP), two wild populations from Poyang Lake (PY) and Dongting Lake (DT), and an H. schlegelii population were collected (JX), and the first filial generations (F1) were bred synchronously. The shell nacre polymorphisms, population genetic diversity, and genetic structures of the F1 of each population were ... more

14-3-3 Proteins; Chromosome Mapping; Gene Expression Regulation, Developmental; Gene Expression Regulation, Plant; Genes, Plant; Multigene Family; Organ Specificity; Panicum; Phylogeny; Stress, Physiological

Members of the 14-3-3 family of proteins are conserved regulatory proteins that are widely found in eukaryotes and play crucial roles in diverse physiological processes, including responses to different stresses. Although genome-wide analysis of 14-3-3 proteins has been performed in a few plant species, it has not been performed in switchgrass. In this study, we identified 21 switchgrass 14-3- ... more

Cinnamyl alcohol dehydrogenase (CAD) catalyzes the final step in lignin biosynthesis. The genus Eucalyptus belongs to the family Myrtaceae, which is the main cultivated species in China. Eucalyptus urophylla GLU4 (GLU4) is widely grown in Guangxi. It is preferred for pulping because of its excellent cellulose content and fiber length. Based on GLU4 and CAD gene expression, a Eucalyptus variety ... more

Pieridae is a butterfly family whose evolutionary history is poorly understood. Due to the difficulties in identifying morphological synapomorphies within the group and the scarcity of the fossil records, only a few studies on higher phylogeny of Pieridae have been reported to date. In this study, we describe the complete mitochondrial genomes of four pierid butterfly species (Aporia martineti ... more
