There is no easy way to identify to species, a small, vegetative leaf or culm sample of a grass and there are more than 12,000 species in this large, important family. The long-range aim of our study is to produce a standard DNA barcode library available to the public for all grasses (±1960 species) in North America (includes all Canada, Mexico and USA) that will facilitate the easy identificat...

Most species of Paraphlomis are distributed in the south Yangtze River China. In this study, a new species, P. nana, from northeast Chongqing north is described and illustrated. Bayesian inference maximum likelihood analyses based on two nuclear ribosomal DNA regions (ITS ETS) three plastid markers (rpl32-trnL, rps16, trnL-trnF) were carried out to explore phylogenetic position within Paraphlom...

the taxonomic and phylogenetic status of several taxa previously recognized as subspecies inastragalus sect. anthylloidei is re-assessed based on dna sequences and morphologicalfeatures. we focused on astragalus ebenoides (subsp. ebenoides and subsp. naghadehensis),astragalus murinus (subsp. murins and subsp. bornmuelleri), astragalus remotiflorus (subsp.remotiflorus and subsp. melanogramma), a...

UNLABELLED PREMISE OF THE STUDY New primers were developed for Bignonieae to enable phylogenetic studies within this clade using herbarium samples. • METHODS AND RESULTS Internal primers were designed based on available sequences of the plastid ndhF gene and the rpl32-trnL intergenic spacer region, and the nuclear gene PepC. The resulting primers were used to amplify DNA extracted from her...

The 50 S subunit of chloroplast ribosomes was prepared from tobacco leaves. The proteins were fractionated and the N-terminal amino acid sequence of a 14 kDa protein was determined. This sequence matches the N-terminal sequence deduced from ORF55 located between ndhF and trnL on the small single-copy region of tobacco chloroplast DNA. The deduced protein shows homology to E. coli and B. stearot...

Typha lepechinii, a new species from European Russia, is described. In terms of the external morphology, it similar to T. shuttleworthii but differs latter by shape female inflorescence, wider leaf blades and geographical distribution. Like shuttleworthii, lepechinii clearly distinct all other cattails sect. Ebracteolatae due its short male inflorescence that 2–4 times shorter than contiguous i...

We have studied several samples from Lotus corniculatus s. l. and L. zhegulensis populations with the use of SSR sequenced nuclear (ITS) plastid (atpB-rbcL, ndhC-trnV, rpl32-trnL(UAG), trnH-psbA, trnL-trnF) markers. analysed 9 local Volga River valley ranging Ulyanovsk in north to Volgograd south, as well two Moscow Lipetsk Provinces. Analyses markers using STRUCRURE program divided sample into...
