Among the fungal pathogens the species Fusariam solani causing systemic infection is very rare and generally causes systemic infection only in an immuno-compromised host. We report a systemic infection caused by F. solani in a non-immunocompromised adult male, to our knowledge the first such case report.
Sheath blight, caused by Rhizoctonia solani anastomosis group 1 subgroup 1A (AG1-1A), is one of the most devastating rice diseases worldwide. Here, we report the draft genome sequence of R. solani AG1-1A strain 1802/KB isolated from a popular Malaysian rice variety. To the best of our knowledge, this is the second reported representative genome from AG1-1A.
An emerging pattern of similarity in medical case reports led to a project to compare the phylogenetic affinities of two well-known tropical fungal opportunistic pathogens, Cylindrocarpon lichenicola and Acremonium falciforme, to members of the Fusarium solani species complex. C. lichenicola and A. falciforme, despite their deviating conidial morphologies, were shown via sequencing of the ribos...
Rhizoctonia solani is an important soil-borne necrotrophic fungal pathogen, with a broad host range and little effective resistance in crop plants. Arabidopsis is resistant to R. solani AG8 but susceptible to R. solani AG2-1. A screen of 36 Arabidopsis ecotypes and mutants affected in the auxin, camalexin, salicylic acid, abscisic acid and ethylene/jasmonic acid pathways did not reveal any vari...
Rhizoctonia solani (Teleomorph: Thanatephorus cucumeris, T. praticola) is a basidiomycetous fungus and a major cause of root diseases of economically important plants. Various isolates of this fungus are also beneficially associated with orchids, may serve as biocontrol agents or remain as saprophytes with roles in decaying and recycling of soil organic matter. R. solani displays several hyphal...
Rhizoctonia solani Kühn infects most plant families and can cause significant agricultural yield losses worldwide; however, plant resistance to this disease is rare and short-lived, and therefore poorly understood, resulting in the use of chemical pesticides for its control. Understanding the functional responses of this pathogen during host infection can help elucidate the molecular mechanisms...
Worldwide, Dickeya (formerly Erwinia chrysanthemi) is causing soft rot diseases on a large diversity of crops and ornamental plants. Strains affecting potato are mainly found in D. dadantii, D. dianthicola and D. zeae, which appear to have a marked geographical distribution. Furthermore, a few Dickeya isolates from potato are attributed to D. chrysanthemi and D. dieffenbachiae. In Europe, isola...
The most popular and important plant Lycopersicon esculentum Mill or Tomato was attacked by several fungal pathogens and several biocontrol agents can be used. Mycorrhizal fungi are mutuality associated with many plant rootswhile actinomycete isolates of the genus Streptomyces enhanced plant growth and decreased plant pathogen development. Thus, interaction between Mycorrhizae and Streptomyces ...
rhizoctonia solani قارچی خاکزیست و برای بقای ساپروفیتی وگسترش خود در خاک توده های متراکم و سخت میسیلیومی تولید میکند. علی رغم تاثیر نسبی پاره ای از مواد شیمیایی در کنترل این بیماری به نظر میرسد کاربرد ترکیبات شیمیایی جهت مهار بیماری از نظر اقتصادی و زیست محیطی قابل توجیه نمی باشد. تصور میشود کنترل بیولوژیک یکی از روش های مناسب مبارزه با این بیماریست.
abstract valerian medicinal plant (valeriana officinalis) is a perennial succulent plant that is natural lenitive and good ingrained of diazepam. this study was conducted in order to identify the fungal agents of rhizome and root rot of valerian. infected plant samples that showed the symptoms of rotting and necrosis were collected from karaj and used in order to isolate disease agents. symptom...
