Genetic structure of Fusarium oxysporum f. sp. ciceri populations from chickpea in Ilam province, Iran

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...

Race 3, a New and Highly Virulent Race of Fusarium oxysporum f. sp. niveum Causing Fusarium Wilt in Watermelon

بررسی هیستوپاتولوژیکی ارقام مقاوم و حساس کاهو در خلال رشد قارچ Fusarium oxysporum f. sp. lactucum

در این بررسی، ارقام Green mingnonett و All year که به ترتیب به قارچ Fusarium oxysporum f.sp. Lactucum مقاوم و حساس هستند، از نظر هیستوپاتولوژیکی مورد مطالعه قرار گرفتند. گیاهچه های 15 روزه به روش غوطه ور کردن ریشه در سوسپانسیون اسپور قارچ عامل بیماری با غلظت 106 × 5 اسپور در میلی لیتر مایه زنی شدند. نمونه برداری در زمان های3، 6، 10 و 20 روز پس از مایه زنی انجام شد. نمونه ها پس از برش و نگهداری ...

Differential Responses of Vanilla Accessions to Root Rot and Colonization by Fusarium oxysporum f. sp. radicis-vanillae

Root and stem rot (RSR) disease caused by Fusarium oxysporum f. sp. radicis-vanillae (Forv) is the most damaging disease of vanilla (Vanilla planifolia and V. × tahitensis, Orchidaceae). Breeding programs aimed at developing resistant vanilla varieties are hampered by the scarcity of sources of resistance to RSR and insufficient knowledge about the histopathology of Forv. In this work we have (...

Antagonistic Effect of Nonpathogenic Fusarium oxysporum Fo47 and Pseudobactin 358 upon Pathogenic Fusarium oxysporum f. sp. dianthi.

Pseudobactin production by Pseudomonas putida WCS358 significantly improves biological control of fusarium wilt caused by nonpathogenic Fusarium oxysporum Fo47b10 (P. Lemanceau, P. A. H. M. Bakker, W. J. de Kogel, C. Alabouvette, and B. Schippers, Appl. Environ. Microbiol. 58:2978-2982, 1992). The antagonistic effect of Fo47b10 and purified pseudobactin 358 was studied by using an in vitro bioa...
