Abstract Background Leishmaniasis is one of the most neglected tropical diseases in world and remains endemic some underdeveloped regions, including western China. The phylogeny classification Chinese Leishmania has not been completely clarified to date, especially within ( L. ) donovani complex, although phylogenetic analyses based on a series gene markers have performed. More analytic methods...

For organisms in which direct observation of mating and subsequent dispersal of offspring and relatives is impossible, patterns of reproductive success and genealogical relationship can only be established using genetic markers. The ideal genetic assay would (1) employ highly polymorphic genetic markers for distinguishing among individuals; (2) use little tissue for analysing early life-history...

charcoal rot caused by macrophomina phaseolina is an injurious and economically important disease which causes heavy loss of yield to field and horticultural crops. thirty-three isolates of m. phaseolina were obtained from different host plants such as: soybean (glycine max.), melo (cucumis melo), bean (phaseolus vulgaris), pea (pisum sativum), pinus (pinus sp), blak-eyed susan (rudbeckia fulgi...

An F(1) mapping population of the septoria tritici blotch pathogen of wheat, Mycosphaerella graminicola, was generated by crossing the two Dutch field isolates IPO323 and IPO94269. AFLP and RAPD marker data sets were combined to produce a high-density genetic linkage map. The final map contained 223 AFLP and 57 RAPD markers, plus the biological traits mating type and avirulence, in 23 linkage g...

Randomly amplified polymorphic DNA (RAPD) has emerged as an effective genetic marker for analysis of Trypanosoma cruzi population variability. This method has been used to study the genetic variability of Mexican T. cruzi stocks and to relate these results to previous classifications. High clonal diversity was observed among the Mexican populations: 24 RAPD types were scored among 56 stocks ana...

The resistance of wild Vitis germplasm, including Chinese and American wild Vitis and Vitis vinifera cultivars, to powdery mildew (Uncinula necator Burr.) was evaluated for two consecutive years under natural conditions. Most of the Chinese and North American species displayed a resistant phenotype, whereas all of the European species were highly susceptible. The Alachua and Conquistador access...

In order to comprehend the plant resources' protection and management in every setting, genetic variousness research is required. Because of minimal number distinguishing morphological features, for example, leaf sequence carpel structure, Alcea includes a problematic taxonomy.34 species are reported Iran among them, 15 endemic. There no specifics. was studied using RAPD (Random Amplified Polym...

The brown planthopper (BPH) is a major insect pest in rice, and damages these plants by sucking phloem-sap and transmitting viral diseases. Many BPH resistance genes have been identified in indica varieties and wild rice accessions, but none has yet been cloned. In the present study we report fine mapping of the region containing the Bph1 locus, which enabled us to perform marker-aided selectio...
