Endophytic bacteria were isolated from the stalks of sugarcane, Saccharum officinarum, growing in Papua New Guinea. Endophytic bacterial communities from extracted juice averaged 6x 10 cfu/ml, which is 25 times greater than the number of endophytic bacteria found in commercial varieties in South Africa. Sixty isolates, representing the different colony morphology types, were used for in vitro i...
ABSTRACT Wheat heads showing symptoms of Fusarium head blight were collected from four commercial fields in Zhejiang Province, China, an area where epidemics occur regularly. A total of 225 isolates were subjected to population-level analyses using restriction fragment length polymorphism (RFLP) as markers. Diagnostic RFLP markers established that all isolates belonged to Fusarium graminearum l...
the purpose of the present study was to investigate the latent pattern underlying reading ability . some 272 male and female participants. english majors at the ba level , participated in the study. two valid tests were used in this study, the reading test developed exclusively for the purpose of this project and academic reading section of ielts. to investigate the possible latent underlying...
The aim of the present study was to genotype Salmonella enterica serotype paratyphi A (SPA) isolated from Yuxi, China, in a multiple-locus variable number of tandem repeats (VNTRs) analysis (MLVA) and to compare them with isolates from the Chinese Medical Culture Collection Center (CMCC). Potential VNTRs were screened from the genomes of ATCC9150 and AKU_12601 using the Tandem Repeats Finder pr...
The objective of this study was to identify Fusarium species in the Gibberella fujikuroi species complex from rice, sugarcane and maize as most of the Fusarium species in the species complex are found on the three crops. Isolates used were collected from the field and obtained from culture collection. The Fusarium isolates were initially sorted based on morphology and identifications confirmed ...
to evaluate fertility status and mating type distribution of cryphonectria parasitica, causal agent of chestnut blight in guilan province, four sites in two main growing regions of: shaft (visrud, taleghan and babarekab), and rezvanshahr (doran) were investigated. during the study, fifty four isolates of c. parasitica were examined. c. parasitica isolates were crossed with each of the two matin...
Pineapple (Ananas comosus L. Merr) is a plant that can live well on nutrient-poor lands such as peatlands. However, resistance to conditions caused by symbiosis with endophytic bacteria capable of growth-promoting (PGPB) through biostimulant and bioprotective mechanisms. This study aims characterize the potential from pineapple roots peatlands biostimulants agents. Thirteen root were characteri...
ABSTRACT Thirty-nine isolates of Fusarium oxysporum were collected from tomato plants displaying wilt symptoms in a field in California 2 years after F. oxysporum f. sp. lycopersici race 3 was first observed at that location. These and other isolates of F. oxysporum f. sp. lycopersici were characterized by pathogenicity, race, and vegetative compatibility group (VCG). Of the 39 California isola...
پژمردگی فوزاریومی خربزه و طالبی با عامل fusarium oxysporum f. sp. melonis از بیماری های مهم قارچی در مناطق رشد این گیاهان می باشد. جدایه های f. oxysporum از گیاهان و خاک ریزوسفر متعلق به پنج استان مهم تولیدکننده ی خربزه و طالبی جداسازی شد و بر پایه ی بیماری زایی در ارقام افتراقی، گروه های سازگاری رویشی (vegetative compatibility groups)، توالی سنجی ناحیه ی جداکننده ی بین ژنی دی اِن اِی ریبوزومی (n...
Species of the Fusarium fujikuroi species complex (FFC) cause a wide spectrum of often devastating diseases on diverse agricultural crops, including coffee, fig, mango, maize, rice, and sugarcane. Although species within the FFC are difficult to distinguish by morphology, and their genes often share 90% sequence similarity, they can differ in host plant specificity and life style. FFC species c...
