Singh, R. P., Bechere, E., and Abdalla, 0. 1992. Genetic analysis of resistance to stem rust in ten durum wheats. Phytopathology 82:919-922. Durum wheat (Triticum turgidum L.) cultivars derived from CIMMYT present in Mexicali 75, Diver, Somorguho, and Morus together with (International Maize and Wheat Improvement Center) germplasm are an unidentified gene, SrC, and in Altar 84, Carcomun, Totanu...

Fungal cereal pathogens, including Blumeria graminis f.sp. avenae, have the ability to adapt specific conditions, which in turn leads overcoming host resistance. An important aspect is standardized way of characterizing races and pathotypes pathogen. In presented work, for first time it was proposed use a unified letter code that allows describing B. avenae. The set 14 oat genotypes were used a...

This research was conducted to evaluate the disease tolerance/resistance of 34 registered chickpea (Cicer arietinum L.) varieties in nurseries under winter climatic conditions Eastern-Mediterranean region located at Eastern Mediterranean Research Institute, Adana. During 2014-2015 sowing season, four different for 4 path types were established with regular observations on tolerance varieties. I...

aim : we aimed to develop a multiplex pcr assay for specific detection of epec and ehec pathotypes based on specific marker genes. background : about 2.5 million infant’s morbidity in developing countries occurs by e.coli pathotypes because of diarrhea and intestinal diseases. the traditional phenotypic methods are time consuming and sometimes detection and differentiation of the pathotypes are...

escherichia coli (e. coli) is a normal inhabitant of the gastrointestinal tract of vertebrates, including humans. phylogenetic analysis has shown that e. coli is composed of four main phylogenetic groups (a, b1, b2 and d). group a and b1 are generally associated with commensals, whereas group b2 is associated with extra-intestinal pathotypes. most enteropathogenic isolates, however, are assigne...

An oligonucleotide microarray detecting 189 Escherichia coli virulence genes or markers and 30 antimicrobial resistance genes was designed and validated using DNA from known reference strains. This microarray was confirmed to be a powerful diagnostic tool for monitoring emerging E. coli pathotypes and antimicrobial resistance, as well as for environmental, epidemiological, and phylogenetic stud...

Leaf or brown rust is one of the most devastating diseases in wheat. Development and deployment resistance wheat cultivars considered as effective, economic sustainable method protecting against yield losses due to leaf rust. Though several alien genes have been reported utilized, Thinopyron ponticum derived gene Lr24/Sr24 has proved be effective for nearly three decades India. The effectivenes...

Guano samples from 412 Brazilian bats were screened with real-time PCR for the virulence genes (eae, est, elt, stx1, stx2, ehxA, invA, bfpA, aggR) representing five intestinal pathotypes of Escherichia coli. From 82 pooled samples, 22% contained Escherichia coli DNA, and eae, est, bfpA, aggR were detected.
