خشکیدگی شاخه در درختان، نهال ها و قلمههای زیتون در ایران و بسیاری از مناطق دنیا یکی از مهم ترین بیماریهای زیتون محسوب میشود. این بیماری در بسیاری از مناطق زیتونکاری کشور از جمله زنجان (طارم)، گرگان و مشهد خسارات زیادی وارد می آورد و شیوع آن رو به گسترش است. به منظور مطالعۀ علل بیماری و کنترل آن، باغها و نهال های زیتون در دو استان زنجان و گلستان در طی سال های 1388،1389 و1390 بررسی شد. نمونه...
Comparative Proteomic Analysis of Gossypium thurberi in Response to Verticillium dahliae Inoculation
Verticillium wilt is threatening cotton productivity globally. This disease is caused by soil-borne Verticillium dahliae which directly infects cotton roots, and exclusively colonizes and occludes xylem vessels, finally resulting in necrosis, defoliation, and most severely, plant death. For the first time, iTRAQ (isobaric tags for relative and absolute quantification) was applied to screen the ...
Verticillium wilt is a vascular disease of cotton. The causal fungus, Verticillium dahliae, secretes elicitors in culture. We have generated approximately 1,000 5'-terminal expressed sequence tags (ESTs) from a cultured mycelium of V. dahliae. A number of ESTs were found to encode proteins harboring putative signal peptides for secretion, and their cDNAs were isolated. Heterologous expression l...
The colonization process of Olea europaea by the defoliating pathotype of Verticillium dahliae, and the in planta interaction with the endophytic, biocontrol strain Pseudomonas fluorescens PICF7 were determined. Differential fluorescent protein tagging was used for the simultaneous visualization of P. fluorescens PICF7 and V. dahliae in olive tissues. Olive plants were bacterized with PICF7 and...
ABSTRACT In a field trial in soil infested with Verticillium dahliae, we compared the yield, growth, incidence of symptoms of Verticillium wilt, and mortality of two interspecific hybrid pistachio tree rootstocks (UCBI and PGII) with the standard rootstocks: the V. dahliae-resistant and susceptible Pistacia integerrima and P. atlantica, respectively. After 10 years, the trees were destructively...
Pasche, J. S., Mallik, I., Anderson, N. R., and Gudmestad, N. C. 2013. Development and validation of a real-time PCR assay for the quantification of Verticillium dahliae in potato. Plant Dis. 97:608-618. An increase in the stringency for higher quality potato tubers and restrictions on the use of soil fumigants, among other factors, has garnered renewed interest in Verticillium wilt, particular...
A fungus with broad spectrum antifungal activity was isolated from the soil in Qinling Mountain, Shaanxi Province, in China. The fungus was identified as Purpureocillium lilacinum based on ITS rDNA gene analysis. The strain, coded as QLP12, showed high inhibition activity on fungal mycelium growth in vitro, especially to Mucor piriformis, Trichothecium roseum, Rhizoctonia solani, and Verticilli...
چکیده پنبه یکی از گرانبهاترین و ارزشمندترین محصولاتی است که از نظر اقتصادی موقعیت خاصی در جهان امروزی به دست آورده است. قارچ عامل بیماری پژمردگی آوندی verticillium dahliaeو نماتد مولد گره ریشه meloidogyne incognita از شایع ترین و مخرب ترین عوامل بیماریزا در پنبه می باشند. به منظور بررسی اثر متقابل بین این دو عامل، نماتد meloidogyne incognita از گیاهان میزبان جدا شد و پس از تعیین گونه و نژاد، ب...
The Ascomycete Verticillium longisporum Is a Hybrid and a Plant Pathogen with an Expanded Host Range
Hybridization plays a central role in plant evolution, but its overall importance in fungi is unknown. New plant pathogens are thought to arise by hybridization between formerly separated fungal species. Evolution of hybrid plant pathogens from non-pathogenic ancestors in the fungal-like protist Phytophthora has been demonstrated, but in fungi, the most important group of plant pathogens, there...
The soilborne fungus Verticillium dahliae is the major pathogen that causes the verticillium wilt disease of plants, which leads to huge economic loss worldwide. At the early stage of infection, growth of the pathogen is subject to the nutrition stress of limited nitrogen. To investigate the secreted pathogenic proteins that play indispensable roles during invasion at this stage, we compared th...
