Sapria himalayana Griff. is a rare and endangered holoparasitic plant that prefers specific host (Tetrastigma sp.). It one of the lesser-known poorly understood plants facing threats extinction owing to human interference in evergreen forests Mizoram. The flower only visible part this endophyte blooms from November December. was encountered for first time forest near Rullam village Serchhip Dis...

An increasing number of phylogenetic analyses are based on the internal transcribed spacer 2 (ITS2). They mainly use the fast evolving sequence for low-level analyses. When considering the highly conserved structure, the same marker could also be used for higher level phylogenies. Furthermore, structural features of the ITS2 allow distinguishing different species from each other. Despite its im...

Ribosomal DNA (rDNA) sequence data were compared for five species of Globodera, including G. rostochiensis, G. pallida, G. virginiae, and two undescribed Globodera isolates from Mexico collected from weed species and maintained on Solanum dulcamara. The rDNA comparisons included both internal transcribed spacers (ITS1 and ITS2), the 5.8S rRNA gene, and small portions of the 3' end of the 18S ge...

BACKGROUND Infectivity of herbivores with Trichostrongylus nematodes is widespread in many countries, having a major economic impact on breeding, survivability, and productivity of domestic livestock. This study was carried out on Trichostrongylus species isolated from domestic livestock in order to develop an easy-to-perform method for species identification. METHODS Trichostrongylus isolate...

Endophytic fungi are inhabitants of plants, living most part of their lifecycle asymptomatically which mainly confer protection and ecological advantages to the host plant. In this present study, 48 endophytic fungi were isolated from the leaves of three medicinal plants and characterized based on ITS2 sequence - secondary structure analysis. ITS2 secondary structures were elucidated with minim...

materials and methods an oligogearray® (an oligonucleotide-based gene expression array platform) containing 126 wnt signaling pathway-related genes was used to compare gene expressions between primary hcc and adjacent non-tumorous liver tissues from 10 patients with hcc. selected differential genes were identified with real-time rt-pcr and immunohistochemistry (ihc). in particular, the protein ...

BACKGROUND In this study, we investigated how to convert the Panax ginseng DNA sequence code and chemical fingerprints into a two-dimensional code. In order to improve the compression efficiency, GATC2Bytes and digital merger compression algorithms are proposed. METHODS HPLC chemical fingerprint data of 10 groups of P. ginseng from Northeast China and the internal transcribed spacer 2 (ITS2) ...

background: the objectives of our research were to search for leishmania species in rodents in fars province, south of iran, and to compare molecular with conventional methods for detecting these para-sites. methods: rodents were captured using live traps and screened for leishmania species using molecular and conventional methods, including the taking of smears from each ear. nested pcr was em...

tropical theileriosis is a tick-transmitted disease which caused by obligative intracellular protozoan theileria annulata. diagnosis is usually based on identification of parasite in giemsa stained smears of peripheral blood, spleen or lymph nodes. today, the molecular methods with high sensitivity and specificity are used for diagnosis of infected and carrier animals, epidemiological and phylo...

Identification of species members of the Hyrcanus Group of Anopheles is difficult because of intraspecific variation in and interspecific similarity among key characters. Hibernating female Anopheles pullus were collected and 6 adults were individually reared. All F1 progeny of wild-caught An. pullus were morphologically identical to An. yatsushiroensis. The 5.8S rDNA-ITS2-28S rDNA region from ...
