A genetic map of Gibberella zeae (Fusarium graminearum).
We constructed a genetic linkage map of Gibberella zeae (Fusarium graminearum) by crossing complementary nitrate-nonutilizing (nit) mutants of G. zeae strains R-5470 (from Japan) and Z-3639 (from Kansas). We selected 99 nitrate-utilizing (recombinant) progeny and analyzed them for amplified fragment length polymorphisms (AFLPs). We used 34 pairs of two-base selective AFLP primers and identified...
متن کاملA novel gene, ROA, is required for normal morphogenesis and discharge of ascospores in Gibberella zeae.
Head blight, caused by Gibberella zeae, is a significant disease among cereal crops, including wheat, barley, and rice, due to contamination of grain with mycotoxins. G. zeae is spread by ascospores forcibly discharged from sexual fruiting bodies forming on crop residues. In this study, we characterized a novel gene, ROA, which is required for normal sexual development. Deletion of ROA (Δroa) r...
متن کاملField testing of antagonists of Fusarium head blight incited by Gibberella zeae
Fusarium head blight (FHB), primarily caused by Gibberella zeae (anamorph1⁄4Fusarium graminearum), is a devastating disease that causes extensive yield and quality losses to wheat and barley throughout the world. Antagonists that suppressed FHB in earlier greenhouse studies were tested in a series of field experiments at different geographical locations in the United States in 1998–2000. In mos...
متن کاملGibberella zeae ascospore production and collection for microarray experiments.
Fusarium graminearum Schwabe (teleomorph Gibberella zeae) is a plant pathogen causing scab disease on wheat and barley that reduces crop yield and grain quality. F. graminearum also causes stalk and ear rots of maize and is a producer of mycotoxins such as the trichothecenes that contaminate grain and are harmful to humans and livestock (Goswami and Kistler, 2004). The fungus produces two types...
متن کاملSymposium contribution / Contribution à un symposium Epidemiology and biological control of Gibberella zeae / Fusarium graminearum
A decade of losses and damage due to fusarium head blight in cereals in North America and other parts of the world has resulted in great efforts to understand the factors that cause and intensify the disease. This review considers our current understanding of the importance of the contribution of cultural practices to the increase or decrease of inoculum levels, spore dispersal, and biological ...
