fusarium solain is the most important pathogen of huge range of plant hosts, especially potato in the word, which causes tuber rot in storage and root rot of potato plants in fields. fifty four isolates from potato, bean, chickpea and cucurbit (melon, watermelon and cucumber) was subjected in a study through analysis of vegetative compatibility groups (vcgs) and rep-pcr dna fingerprinting. nit ...
this study investigates the effect of teacher’s repetition as an input enhancement technique in explicit teaching of vocabulary items on efl learners’ later retrieval. to this end, 66 persian speaking english learners, aged 18 - 29, homogenized through a standard proficiency test (opt), were chosen and put into two experimental and control groups, each 33 learners. general service list (gsl), a...
this study purported to compare and contrast the use of self-mention and evidentials as two mtadiscourse features in opinion columns of persian and english newspapers. the theoretical basis of this study is the idea that metadiscourse features vary across cultural boundaries. for this purpose, 150 persian and 150 english opinion columns were collected based on three factors of topic, audience a...
burnout is a response to the chronic work stress which is prevalent mostly among the people who do people job, like teaching. the purpose of this study was to develop a valid and reliable instrument that can measure burnout in foreign language teachers. although some widely used instruments were developed before which measured burnout in teachers, a specific instrument which include specific sy...
pasteurella multocida is considered to be an important cause of ovine pneumonia and results causes considerable economic losses in iran. ribotyping pcr (ribo-pcr) was used for investigating the diversity of ovine and caprine p.multocida. a total of 120 swab tonsil and nasal samples were obtained from sheep and goats. they were analyzed by biochemical tests and ribo-pcr 16s-23s ribosomal rna gen...
Pasteurella multocida is considered to be an important cause of ovine pneumonia and results causes considerable economic losses in Iran. Ribotyping PCR (Ribo-PCR) was used for investigating the diversity of ovine and caprine P.multocida. A total of 120 swab tonsil and nasal samples were obtained from sheep and goats. They were analyzed by biochemical tests and Ribo-PCR 16S-23S ribosomal RNA gen...
During studies in which we serotyped large numbers of Chlamydia trachomatis clinical isolates by using monoclonal antibodies, three novel serological variants (D-, D*, and I-) were identified. To determine the molecular basis for the altered monoclonal antibody reactions of these strains and other previously identified variants (Da, Ia, and L2a), we determined the nucleotide sequences of the va...
Chickpea (Cicer arietinum L.) is one of the most important legume crops in Iran. Wilt disease caused by Fusarium oxysporum f. sp. ciceri, is the most important soil-borne disease of chickpea in the world. This disease caused high losses in different regions during recent years. Simple sequence repeat (SSR) were used to estimate genetic diversity in 114 of F. oxysporum isolates from six counties...
Abstract Cucumber mosaic virus (CMV) is a tremendous threat to vegetables across the globe, including in Pakistan. The present work was conducted investigate genetic variability of CMV isolates infecting pea and spinach Pothwar region Serological-based surveys during 2016-2017 revealed 31.70% overall disease incidence from crops. Triple-antibody sandwich enzyme-linked immunosorbent assay (TAS-E...
