Biotic stress, as a result of plant-pathogen interactions, induces the accumulation of reactive oxygen species in the cells, causing severe oxidative damage to plants and pathogens. To overcome this damage, both the host and pathogen have developed antioxidant systems to quench excess ROS and keep ROS production and scavenging systems under control. Data on ROS-scavenging systems in the necrotr...

Rhizoctonia solani causes crown rot of sugar beets, a severe disease that has destroyed up to 60% of the plants in a test field in western Nebraska. Laetisaria arvalis, a natural hyperparasite of Rhizoctonia spp., was isolated from fields in western Nebraska. To test for the potential for biological control of R. solani, in November 1980 (following harvest) we applied various combinations of a ...

The soil-borne fungus Rhizoctonia solani causes damping-off on sugar beet seedlings. Growers rely fungicides to protect in fields affected by R. solani. Quinone outside inhibitor (QoI) fungicides, such as azoxystrobin, have been applied in-furrow and foliar sprays manage solani, but repeated use of QoI pose risks fungicide resistance. Penthiopyrad is a novel with the succinate dehydrogenase (SD...

the antagonistic effects of rhizobium spp. isolates against rhizoctonia solani (ag-4), the causal agent of bean damping-off were compared with each other in either of the in vitro and in vivo conditions. also their potential to produce such secondary antifungal metabolites as hcn, siderophore and protease were evaluated. the results indicated that, isolate rh3 reduced mycelial growth of r. sola...

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.

Gottlieb, David (University of Illinois, Urbana), and James L. Van Etten. Changes in fungi with age. I. Chemical composition of Rhizoctonia solani and Sclerotium bataticola. J. Bacteriol. 91:161-168. 1966.-The chemical composition of the mycelium of Rhizoctonia solani and Sclerotium bataticola was determined in cells of various ages. The percentage, per unit of dry weight, of soluble amino nitr...

root colonization by antagonist bacteria has been considered as a prerequisite for a successful biocontrol. for an effective suppression of plant disease, an efficient and fast colonization is necessary to prevent the establishment of pathogen on the root system. colonization of canola root by strain utpf86 were investigated with and without rhizoctonia solani ag-4, under greenhouse conditions....
