Fusarium graminearum-induced changes in gene expression between Fusarium head blight-resistant and susceptible wheat cultivars.

Fusarium head blight (FHB), primarily caused by Fusarium graminearum Schw., is a destructive disease of wheat (Triticum aestivum L.).

Cold hardiness of wheat near-isogenic lines differing in vernalization alleles.

Four major genes in wheat (Triticum aestivum L.), with the dominant alleles designated Vrn-A1, Vrn-B1, Vrn-D1, and Vrn4, are known to have large effects on the vernalization response, but the effects on cold hardiness are ambiguous. Near-isogenic experimental lines (NILs) in a Triple Dirk (TD) genetic background with different vernalization alleles were evaluated for cold hardiness.

Evidence that the 37 kDa protein of Soil-borne wheat mosaic virus is a virus movement protein.

Experiments were conducted to determine if the 37 kDa protein (37K) of Soil-borne wheat mosaic virus (SBWMV) is a virus movement protein. First, evidence was obtained that indicated that 37K has the ability to move from cell to cell, similar to other virus movement proteins (MPs). Plasmids containing the GFP gene fused to the SBWMV 37K, the coat protein (CP) or the CP readthrough domain (RT) ORFs were delivered by biolistic bombardment to wheat and tobacco leaves.

Tolerance of mannitol-accumulating transgenic wheat to water stress and salinity.

Previous work with model transgenic plants has demonstrated that cellular accumulation of mannitol can alleviate abiotic stress. Here, we show that ectopic expression of the mtlD gene for the biosynthesis of mannitol in wheat improves tolerance to water stress and salinity. Wheat (Triticum aestivum L.
