Diseases caused by Alternaria sp. are among the most common diseases of crops throughout the world. Alternaria sp. is a common component of the flora of wheat seed. Although isolation of Alternaria sp. from wheat (Triticum aestivum) seed has been reported in Argentina, development of the Alternaria blight in plants from infected seeds has not been demonstrated experimentally. Seed transmission ...

Dear Editor, We read with interest the article by Gorelick et al. [1], who assayed the diabetogenic potential of two ancestral wheat landraces (Triticum turgidum ssp. dicoccoides and spp. dicoccum), compared to a modern wheat cultivar (T. aestivum) in NOD mice. [...].

Fusarium head blight (FHB) is a serious disease of wheat worldwide. Cultivar resistance to FHB depends on biochemical factors that confine the pathogen spread in spikes. Breeding for cultivar resistance is considered the most practical way to manage this disease. In this study, different spectroscopy and microscopy techniques were applied to discriminate resistance in wheat genotypes against FH...

The wheat stem sawfly, Cephus cinctus Norton, causes severe losses in wheat grown in the northern Great Plains. Much of the affected area is planted in monoculture with wheat, Triticum aestivum L., grown in large fields alternating yearly between crop and no-till fallow. The crop and fallow fields are adjacent. This cropping landscape creates pronounced edge effects of sawfly infestations and m...

Rye (Secale cereale L.) possesses many valuable genes that can be used for improving disease resistance, yield and environment adaptation of wheat (Triticum aestivum L.). However, the documented resistance stocks derived from rye is faced severe challenge due to the variation of virulent isolates in the pathogen populations. Therefore, it is necessary to develop desirable germplasm and search f...

Salt stress dramatically reduces crop yield and quality, but the molecular mechanisms underlying salt tolerance remain largely unknown. To explore the wheat transcriptional response to salt stress, we performed high-throughput transcriptome sequencing of 10-day old wheat roots under normal condition and 6, 12, 24 and 48 h after salt stress (HASS) in both a salt-tolerant cultivar and salt-sensit...

In undertaking cultivar trials, the variability of the response of the cultivars to the di¡erent environments in which they are grown introduces the possibility of release errors and non-release errors in the decisions made on the basis of the trial results. In this article a model is developed that accounts for the economic costs of those errors as well as the costs of operating the trials, an...

Diseases can greatly lower wheat yield and grain quality. Leaf rust, Stagnospora (Septoria) glume blotch, Septoria leaf blotch, and powdery mildew have historically been the most damaging diseases on wheat in Alabama. Stripe rust has recently emerged in the Deep South as a very destructive disease of wheat. Field cropping history, cultivar selection, and weather patterns all have a tremendous i...
