Advanced backcross families derived from Oryza sativa cv MR219/O. rufipogon IRGC105491 were utilized for identification of quantitative trait loci (QTL) for blast resistance using simple sequence repeat markers. Two hundred and sixty-one BC(2)F(3) families were used to construct a linkage map, using 87 markers, which covered 2375.2 cM of 12 rice chromosomes, with a mean density of 27.3 cM. The ...

Yellow (stripe) rust, caused by Puccinia striiformis f. sp. tritici (Pst), is a major disease of common wheat worldwide. Disease epidemics in Russia have been frequent and destructive, mostly the North Caucasus. However, over last 5 years, significance Pst has markedly increased other Russian regions. Therefore, virulence diversity was investigated Triticum aestivum six geographically distant r...

Due to the increased importance of angular leaf spot of common bean (Phaseolus vulgaris) in Brazil, monitoring the pathogenic variability of its causal agent (Phaeoisariopsis griseola) is the best strategy for a breeding program aimed at developing resistant genotypes. Fifty one isolates of P. griseola collected in five Brazilian States were tested on a set of 12 international differential cult...

Collared peccaries (Pecari tajacu) roam the forests of natural areas in America. Wild collared peccary appears to be a carrier for bacteria associated with infections humans and animals, however, presence diarrheagenic E. coli (DEC) pathotypes has not been studied captive peccary. This study aimed prevalence DEC, susceptibility antibiotics, frequency β-lactamase genes (ESBL) faeces. DEC strain...
