ABSTRACT The genetic diversity of Ralstonia solanacearum strains isolated from ginger (Zingiber officinale) growing on the island of Hawaii was determined by analysis of amplified fragment length polymorphisms (AFLPs). Initially 28 strains of R. solanacearum collected from five host plant species worldwide were analyzed by AFLP. A second analysis was conducted on 55 R. solanacearum strains coll...
Ralstonia solanacearum is an extremely destructive pathogen able to cause disease in a wide range of host plants. Here we report the draft genome sequences of the strains FJAT-91, FJAT-452 and FJAT-462, isolated from tomato, eggplant, and chili pepper, respectively, in China. In addition to the genome annotation, we performed a search for type-III secreted effectors in these strains, providing ...
Type III effectors from phytopathogenic bacteria exhibit a high degree of functional redundancy, hampering the evaluation of their precise contribution to pathogenicity. This is illustrated by the GALA type III effectors from Ralstonia solanacearum, which have been shown to be collectively, but not individually, required for disease on Arabidopsis thaliana and tomato. We investigated evolution,...

Ralstonia solanacearum is one of the most devastating bacterial plant pathogens due to its large host range, worldwide geographic distribution and persistence in fields. This soilborne pathogen is the causal agent of bacterial wilt and it can infect major agricultural crops thereby reducing significantly their yield. To favor infection, the bacterium delivers, through the type three secretion s...
is the major bacterial disease in tomato, Background: Ralstonia solanacearum which invades the roots of diverse plant hosts and colonizes xylem vessels causing wilt, especially in tropical, subtropical and warm-temperate regions. R. produces several toxins helping it to invade the plant’s natural solanacearum defense mechanism. Native isolates of Trichoderma spp., Pseudomonas and can be used as...
Ralstonia solanacearum is a pathogenic bacterium that causes wilt in over 200 plant species. Here we report a rapid and sensitive detection of R. solanacearum using an isothermal method for copying DNA known as loop-mediated amplification (LAMP). A set of four primers was designed to replicate the gene coding for the flagellar subunit, fliC, and conditions for detection were optimized to comple...
امروزه استفاده از اسانس های گیاهی برای دستیابی به مواد ضدباکتریایی طبیعی برای کنترل عوامل بیماری زای گیاهی مورد توجه فراوان قرار گرفته است. در این تحقیق اثر بازدارندگی اسانس پنج گیاه آویشن باغی (thymus sativum l.)، گشنیز (coriandrum sativum l.)، زیره سبز (cuminum cyminum l.)، رزماری (rosmarinus officinalis l.) و اکالیپتوس(eucalyptus globules l.) با روش تقطیر با آب استخراج و اثر بازدارندگی آنها ...
طی تابستان سال 1383 نمونه هایی از غده و ساقه سیب زمینی دارای علایم پوسیدگی و پژمردگی از مزارع مختلف استان های آذربایجان شرقی، فارس و کرج جمع آوری شدند. تعداد 39 جدایه باکتریایی جداسازی گردید و بر اساس مشخصات مرفولوژیکی، بیوشیمیایی و خصوصیات بیماری زایی به دو گروه مشخص تقسیم شدند. تمام جدایه های استان آذربایجان شرقی و کرج به عنوان نژاد 3 / بیووار 2a باکتری ralstonia solanacearum معرفی شدند و ج...
