Weedy invasive Cirsium spp. are widespread in temperate regions of North America and some of their biological control agents have attacked native Cirsium spp. A phylogenetic tree was developed from DNA sequences for the internal transcribed spacer and external transcribed spacer regions from native and non-native Great Plains Cirsium spp. and other thistles to determine if host specificity foll...

Multiple closely related species with genomic sequences provide an ideal system for studies on comparative and evolutionary genomics, as well as the mechanism of speciation. The whole genome sequences of six strawberry species (Fragaria spp.) have been released, which provide one of the richest genomic resources of any plant genus. In this study, we first generated seven transcriptome sequences...

OBJECTIVE We analyzed the symbiotic efficiency and genetic diversity of rhizobia isolated from Leucaena leucocephala in Liangshan Prefecture of SichuanProvince. METHODS We studied genetic diversity of these isolates with 16S rRNA RFLP, BOX-PCR and AFLP fingerprinting, and constructed phylogenetic tree based on the concatenated sequences of the four housekeeping genes 16S rRNA, recA, atpD and ...

Abstract Thioredoxin (TRX) is a highly conserved low-molecular-weight protein and ubiquitous antioxidant enzyme that plays key role in the regulation of plant growth development. Here, using whole-genome sequence, we performed systematic analysis for TRX gene family upland cotton ( Gossypium hirsutum L.) analyzed their structural characteristics, evolution, expression profiles during At least 8...

The identification, differentiation and classification of microorganisms have been subjects of research for many years. Recently, Fourier transform infrared (FTIR) spectroscopy techniques have gained attention in the characterization and classification of microorganisms based on biochemical profiles and cell structure characteristics. In the present study, the characterization and differentiati...
