resistance gene analog polymorphism (rgap) markers linked to fusarium head blight resistance (fhb) and co-localize with qfhs.ndsu-3bs were identified using f3 plants and f3:5 lines derived from a ‘wangshuibai’ (resistant) / ‘seri82’ (susceptible) cross. the mapping populations were genotyped using 50 degenerate primers designed based on the known r genes. out of the 50 designed primer combinati...

Two complementary approaches are being pursued at the University of Arkansas to develop FHB-resistant cultivars for the Mid-south. Following a severe outbreak of FHB in 1991, the breeding program initiated a crossing program between adapted soft wheat genotypes and 22 FHB lines from CIMMYT and Eastern Europe. These populations were advanced as bulks for 5 years. Then lines were developed using ...

Fusarium head blight (FHB), mainly caused by graminearum, is one of the most devastating diseases wheat globally. FHB causes an extensive reduction in yield and reduces grain quality through its contamination with toxins such as deoxynivalenol (DON), T2 toxin, HT-2 nivalenol, zearalenone. This review provides overview updated progress genetic studies on resistance to FHB, emphasis sources gene/...

Over the past century, economically devastating Fusarium Head Blight (FHB) disease has persistently ravished small grain cereal crops worldwide. Annually, losses globally are in billions of United States dollars (USD), with common bread wheat and durum accounting for a major portion these losses. Since unforgettable FHB epidemics 1990s early 2000s North America, different management strategies ...

Small grains crop yield and quality losses resulting from Fusarium head blight (FHB) continue to threaten the economic sustainability of many small grains producers in Minnesota. Spring wheat breeders have made some progress in developing cultivars with moderate levels of disease resistance, but increased resistance in barley has not been achieved. Crop rotation and a timely application of fung...

Microorganisms have developed mechanisms to combat reactive nitrogen species (RNS); however, only a few of the fungal genes involved have been characterized. Here we screened RNS-resistant Aspergillus nidulans strains from fungal transformants obtained by introducing a genomic DNA library constructed in a multicopy vector. We found that the AN0121.3 gene (hemC) encodes a protein similar to the ...

In cases of fetal heartbeat- (FHB-) positive cesarean scar pregnancy (CSP), the embryo and placenta grow rapidly week by week. We experienced an FHB-positive CSP case at 6 weeks of gestation and assessed the CSP in detail with transvaginal ultrasound and transabdominal ultrasound (TAUS), preoperatively. We performed Laminaria cervical dilatation under TAUS guidance and performed hysteroscopic r...

ABSTRACT Fusarium head blight (FHB), caused by Gibberella zeae, is a devastating disease of wheat worldwide. Cryptococcus nodaensis OH 182.9 is an effective biocontrol agent for this disease. Development of a dried product of OH 182.9 would have potential advantages of ease of handling, favorable economics, and acceptance by end users. Isolate OH 182.9 was grown for 48 and 72 h in semi-defined ...

fusarium head blight (fhb) caused by fusarium graminearum is a serious disease of wheat (triticum aestivum l.), through which grain quality losses are induced by fungal trichotecene mycotoxins such as deoxynivalenol (don). a class of plasma membrane localized abc transporter proteins related to the yeast pdr5 (pleiotropic drug resistance5) efflux pump seems to be responsible for partial resista...
