Fusarium wilt is an endemic disease in El Barco de Avila (Castilla y León, west-central Spain), where high-quality common bean cultivars have been cultured for the last century. We used intergenic spacer (IGS) region polymorphism of ribosomal DNA, electrophoretic karyotype patterns, and vegetative compatibility and pathogenicity analyses to assess the genetic diversity within Fusarium oxysporum...
a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...
Fusarium wilt caused by Fusarium oxysporum f.sp. canariensis has caused the death of hundreds of Canary Island date palms, Phoenix canariensis, in Sydney where they have been used prominently in landscape plantings. The fungus is spread in soil, by transplanting palms and on contaminated pruning implements and possibly by seed, birds and insects. Vegetative compatibility groupings (VCGs) were u...
The poor information available on variation of Ascochyta blight fungus is the most important factor limiting chickpea breeding programs for resistance to blight disease. In this study, efforts were made to detect genetic variation of the pathogen in Iran. The RAPD marker was employed to evaluate 26 isolates collected from 16 provinces. Twelve random primers were used to analyze genomic DNA of t...
We used an in silico approach to survey and compare microsatellites in transcript sequences of four sequenced members of genus Fusarium. G + C content of transcripts was found to be positively correlated with the frequency of SSRs. Our analysis revealed that, in all the four transcript sequences studied, the occurrence, relative abundance and density of microsatellites varied and was not influe...
BACKGROUND To characterize Fusarium isolates from recent cases of fungal keratitis in contact lens wearers, and to investigate fungal association with MoistureLoc solution. METHODS We studied six fungal isolates from recent cases of keratitis in New York State. The isolates were characterized by nucleotide sequencing and phylogenetic analyses of multiple genes, and then typed using minisatell...
In order to evaluate the effect of different Trichoderma isolates on reducing the effects of drought stress on Polianthes tuberose, two factorial experiments were carried out based on completely randomized design with three replications. The first factor in the first experiment was bi isolate, and in the second experiment was isolate 65 of Trichoderma harzianum, each at three levels (0, 10, 20%...
Mycotoxins contamination is one of the most important problems worldwide in maize that can cause serious threat for human and animal health. The aim of this study was to determine the ability of Fusarium species associated with maize ear rot to produce diverse mycotoxins. The results showed, One out of three isolates of F. subglutinans produced detectable level of beauvericin ...
for a given riemannian manifold (m,g),it is an interesting question to study the existence of a conformal diffemorphism (also called as a conformal transformation) f : m ! m such that the metric g? = fg has one of the following properties: (i)(m; g?) has constant scalar curvature. (ii)(m; g?) is an einstein manifold.
the present paper investigates how far ideologies can be tease out in discourse by examining the employed schemata by two ideologically opposed news media, the bbc and press tv, to report syria crisis during a period of nine months in 2011. by assuming that news is not a valuefree construction of facts and drawing on micro structural approach of schema theory, for the first time in discours...
