Abstract:

Interactions among Gaeumannomyces graminis var. tritici, Trichoderma koningii, and soil bacteria were studied in vitro and in soils suppressive and conducive of the saprophytic growth of G. graminis var. tritici. Fifty-four percent of bacteria isolated from the suppressive soil and 10% from the conducive soil were antagonistic to G. graminis var. tritici in vitro. The reduction in the growth of T. koningii in vitro by metabolite(s) produced in pure culture by soil bacteria was 14 and 28% for the bacteria isolated from the suppressive and conducive soil, respectively. Metabolite(s) produced by

Abstract:

Wheat take-all disease caused by Gaeumannomyces graminis var. tritici has recently been detected in different regions of Iran. With respect to biocontrol effect of Trichoderma spp. on many pathogenic fungi, seven isolates of Trichoderma and four isolates of Talaromyces were in vitro evaluated in terms of their biological control against the disease causal agent. In dual culture test the five isolates showed efficient competition for colonization against pathogenic fungus and the highest percentages of inhibition belonging to Talaromyces flavus 60 and Talaromyces flavus 136 were 59.52 and 57.61

Abstract:

Avenacinase activity has been shown to be a key factor determining the host range of Gaeumannomyces graminis on oats (Avena sativa). G. graminis var. avenae produces avenacinase, which detoxifies the oat root saponin avenacin, enabling it to infect oats. G. graminis var. tritici does not produce avenacinase and is unable to infect oats. G. graminis var. avenae is also reported to incite take-all patch on creeping bentgrass (Agrostis stolonifera). It is unknown whether creeping bentgrass produces avenacin and if the avenacin-avenacinase interaction influences G. graminis pathogenicity on creepi

Gaeumannomyces graminis var. tritici causes take-all disease, the most important root disease of cereal plants. Cereal plants are able to form a symbiotic association with soil-borne arbuscular mycorrhizal fungi which can provide bioprotection against soil-borne fungal pathogens. However, the bioprotective effect of arbuscular mycorrhizal fungi against soil-borne fungal pathogens might vary. In the present study we tested the systemic bioprotective effect of the arbuscular mycorrhizal fungi Glomus mosseae, Glomus intraradices and Gigaspora rosea against the soil-borne fungal pathogen Gaeumanno

Abstract:

Take-all, a disease caused by the fungus Gaeumannomyces graminis var. tritici, is the most important root disease of wheat and causes severe yield losses worldwide. Using microorganisms as biological agents to control the disease is important because no resistant cultivars or effective chemical fungicides are available. In this study, we tested the biological control capability of a chitinase produced by the endophytic bacterium Serratia proteamaculans 336x against wheat take-all. The chitinase gene chi1 of S. proteamaculans 336x was cloned and heterologously expressed in Escherichia coli. The

Abstract:

Takeall (causal agent Gaeumannomyces graminis var tritici) is one of the most important soilborne diseases of wheat Greenhouse screening of microorganisms for disease suppression was conducted using a targeted approach that focused on the fungal genus Trichoderma In spite of indications of disease suppression in preliminary assays effective biocontrol was not observed in subsequent tests Explanations for this apparent loss of disease suppression could include insufficient numbers of potential biocontrol agents screened during the selection process or the issue of falsepositive (type 1 error) r

Abstract:

Cultural practices are the principle means for managing take-all of wheat caused by Gaeumannomyces graminis var. tritici. This research identified cropping sequences that can be used to manage take-all in Arkansas. For dryland fields where the opportunity to grow rotational crops is limited, summer fallow was the best option for managing take-all. For irrigated fields, rotation out of wheat for at least one year reduced incidence and severity of take-all, and rice was the most effective rotational crop. Summer fallow or a rice crop was more detrimental to survival of take-all inoculum compared

Abstract:

Effector proteins secreted by plant pathogens play important roles in promoting colonization. Blumeria effector candidate (BEC) 1019, a highly conserved metalloprotease of Blumeria graminis f. sp. hordei (Bgh), is essential for fungal haustorium formation, and silencing BEC1019 significantly reduces Bgh virulence. In this study, we found that BEC1019 homologs in B. graminis f. sp. tritici (Bgt) and Gaeumannomyces graminis var. tritici (Ggt) have complete sequence identity with those in Bgh, prompting us to investigate their functions. Transcript levels of BEC1019 were abundantly induced concom
