Rhizoctonia solani isolates obtained from common beans (Phaseolus vulgaris L.) were included in an AG4 anastomosis group in accordance with hyphal anastomosis. In the subgrouping of AG4 isolates, PCR-RFLP patterns in the rDNA-ITS were used. After obtaining the genomic DNA belonging to R. solani AG4, an approximately 700 bp amplification product of the ITS1-5.8S-ITS2 region was obtained with PCR...

In order to find new lead compounds with high fungicidal activity, (Z/E)-3,7-dimethyl-2,6-octadienoic acids were synthesized via selective two-step oxidation using the commercially available geraniol/nerol as raw materials. Twenty-eight different (Z/E)-3,7-dimethyl-2,6-octadienamide derivatives were prepared by reactions of (Z/E)-carboxylic acid with various aromatic and aliphatic amines, follo...

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...

Background. Bioactive microbial metabolites provide a successful source of novel compounds with pharmaceutical potentials. The bacterium Pseudomonas sp. In5 is a biocontrol strain isolated from a plant disease suppressive soil in Greenland, which produces two antimicrobial nonribosomal peptides (NRPs), nunapeptin and nunamycin. Methods. In this study, we used in vitro antimicrobial and anticanc...

In January 2021, unusual outbreak of shoot rot symptoms was observed in young spikenard (Aralia cordata) plants growing vinyl greenhouses located Chuncheon and Yanggu, Gangwon Province, Korea. The initially appeared on shoots the at or above soil surface level. Later, infected wholly rotted blighted. incidence diseased investigated ranged from 5% to 30%. Eight isolates Rhizoctonia sp. were obta...

The form genus Rhizoctonia D.C. is regarded as a heterogeneous assemblage of filamentous fungal taxa that do not produce asexual spores and share a number of common features in their anamorphic states (Garcia et al. 2006). It includes several of the most devastating crop pathogens such as Rhizoctonia solani Kühn [teleomorph = Thanatephorus cucumeris (A.B. Frank) Donk]. In the absence of a perfe...
