A series of benzimidazole phenylhydrazone derivatives (6a-6ai) were synthesized and characterized by ¹H-NMR, ESI-MS, and elemental analysis. The structure of 6b was further confirmed by single crystal X-ray diffraction as (E)-configuration. All the compounds were screened for antifungal activity against Rhizoctonia solani and Magnaporthe oryzae employing a mycelium growth rate method. Compound ...
Rhizoctonia solani is a major fungal pathogen of rice (Oryza sativa L.) that causes great yield losses in all rice-growing regions of the world. Here we report the draft genome sequence of the rice sheath blight disease pathogen, R. solani AG1 IA, assembled using next-generation Illumina Genome Analyser sequencing technologies. The genome encodes a large and diverse set of secreted proteins, en...
Tall fescue (Festuca arundinacea Schreb.) is an open-pollinated, perennial, cool-season turf and forage grass species of great economic importance. The main problems of maintenance of tall fescue, and many other turfgrasses, are two severe fungal diseases: gray leaf spot caused by Magnaporthe grisea, and brown patch caused by Rhizoctonia solani. Three genes from various sources have been introd...
Disease resistance in transgenic plants has been improved, for the first time, by the insertion of a gene from a biocontrol fungus. The gene encoding a strongly antifungal endochitinase from the mycoparasitic fungus Trichoderma harzianum was transferred to tobacco and potato. High expression levels of the fungal gene were obtained in different plant tissues, which had no visible effect on plant...
ABSTRACT The relative contribution of migration of Rhizoctonia solani anastomosis group 3 (AG-3) on infested potato seed tubers originating from production areas in Canada, Maine, and Wisconsin (source population) to the genetic diversity and structure of populations of R. solani AG-3 in North Carolina (NC) soil (recipient population) was examined. The frequency of alleles detected by multilocu...
Compliance with ethical standards: This study did not involve human participants and animals, and the plant of interest is not an endangered species. Polygalacturonase-inhibiting proteins (PGIPs) are leucine-rich repeat proteins that plants produce against polygalacturonase, a key virulence agent in pathogens. In this paper, we cloned and purified CkPGIP1, a gene product from Cynanchum komarovi...
The transmission of viral infections between plant and fungal hosts has been suspected to occur, based on phylogenetic and other findings, but has not been directly observed in nature. Here, we report the discovery of a natural infection of the phytopathogenic fungus Rhizoctonia solani by a plant virus, cucumber mosaic virus (CMV). The CMV-infected R. solani strain was obtained from a potato pl...
Execute search by date 1/4/2021, The results of collecting samples from the regions Anbar, Baghdad, Salah al-Din and Wasit showed that cowpea root rot disease is widespread in all studied areas, isolation phenotypic molecular diagnosis presence different fungi infected root, such as Fusarium nygamai (Fu1), F. (Fu2), solani (Fu3), solani(Fu4), Rhizoctonia (Rh5), (Fu6), pathogenicity test on radi...
The capability of endophytic Trichoderma spp. to reduce sheath blight disease in rice caused by Rhizoctonia solani was assessed under the growth conditions established practices System Rice Intensification (SRI), compared those standard irrigated cultivation. seeds inoculated with a local isolate fungus asperellum SL2 were grown respective SRI and conventional or uninoculated plants then infect...
در سال های 1386 و 1387 از مزارع باقلا در استان لرستان از گیاهان مشکوک به پوسیدگی ریشه و طوقه باقلا، نمونه برداری شد و در مجموع 121 جدایه قارچ و کرومیستا جدا شد. در این بررسی مشخص شد که فراوانی قارچ fusarium solani که موجب پوسیدگی ریشه باقلا می شود، از سایر جدایه ها بیشتر و خسارت ناشی از آن در مزارع استان زیاد است و بعد از آن بیشترین فراوانی به ترتیب متعلق به گونه های f. oxysporum، rhizoctonia s...
