Verticillium wilt, caused by soil-borne fungi of the genus Verticillium, is an economically important disease that affects a wide range of host plants. Unfortunately, host resistance against Verticillium wilts is not available for many plant species, and the disease is notoriously difficult to combat. Host-induced gene silencing (HIGS) is an RNA interference (RNAi)-based process in which small ...

Verticillium wilt, caused by the Verticillium dahliae phytopathogen, is a devastating disease affecting many economically important crops. A receptor-like protein (RLP) gene, Ve1, has been reported to confer resistance to V. dahliae in tomato plants, but few genes have been found to be involved in cotton Verticillium wilt resistance. Here, we cloned two RLP gene homologs, Gossypium barbadense r...

Verticillium wilt caused by soilborne fungus Verticillium dahliae could significantly reduce cotton yield. Here, we cloned a tomato Ve homologous gene, Gbve1, from an island cotton cultivar that is resistant to Verticillium wilt. We found that the Gbve1 gene was induced by V. dahliae and by phytohormones salicylic acid, jasmonic acid, and ethylene, but not by abscisic acid. The induction of Gbv...

Verticillium wilt is a soil-borne disease that can cause devastating losses in cotton production. Because there is no effective chemical means to combat the disease, the only effective way to control Verticillium wilt is through genetic improvement. Therefore, the identification of additional disease-resistance genes will benefit efforts toward the genetic improvement of cotton resistance to Ve...

جنس گیاهان هسته دار (prunus) با تعداد زیادی گونه، یک جنس با گسترش جهانی و با بیش ترین تنوع بومی در آسیا است. انواع مختلفی از محصولات میوه ای از درختان متعلق به این جنس در ایران و در استان آذربایجان غربی تولید می شود که به مصرف خوراکی یا فرآوری و تولیدات داروئی می رسد. انواع مختلفی از عوامل بیماری زای گیاهی اعم از باکتریایی، قارچی و ویروسی این درختان را مورد حمله قرار داده و باعث کاهش عملکرد یا ...

Accurate species identification is essential for effective plant disease management, but is challenging in fungi including Verticillium sensu stricto (Ascomycota, Sordariomycetes, Plectosphaerellaceae), a small genus of ten species that includes important plant pathogens. Here we present fifteen PCR assays for the identification of all recognized Verticillium species and the three lineages of t...

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، با تلقیح...

Verticillium wilt is a devastating disease of cotton, which is caused by the soil-borne fungus Verticillium dahliae (V. dahliae). Although previous studies have identified some genes or biological processes involved in the interaction between cotton and V. dahliae, its underlying molecular mechanism remains unclear, especially in G. hirsutum. In the present study, we obtained an overview of tra...

Verticillium dahliae is a causative fungal pathogen and only a few genes have been identified that exhibit critical roles in disease resistance and few has shown positive effects on the resistance to Verticillium wilt in transgenic cotton. We cloned a receptor-like kinase gene (GbRLK) induced by Verticillium dahliae (VD) in the disease-resistant cotton Gossypium barbadense cv. Hai7124. Northern...

Verticillium wilt caused by Verticillium dahliae results in severe losses in cotton, and is economically the most destructive disease of this crop. Improving genetic resistance is the cleanest and least expensive option to manage Verticillium wilt. Previously, we identified the island cotton NBS-LRR-encoding gene GbaNA1 that confers resistance to the highly virulent V. dahliae isolate Vd991. In...
