Background: Dietary intake of wheat causes hypersensitivity reactions in patients suffering from IgE-mediated food allergy and coeliac disease.
Aim: To study the expression of IgE- and IgA-reactive antigens during wheat seed maturation and in different wheat cultivars.
Methods: Summer wheat was grown in a glasshouse and seeds were harvested at defined maturation stages. Mature seeds were obtained from 13 different defined cultivars. Protein extracts were prepared from different maturation stages and cultivars with a standardized procedure based on seed weight and analysed by IgE and IgA immunoblotting using sera from clinically defined patients suffering from wheat allergy or coeliac disease.
Results: With a few exceptions the expression of IgE- and IgA-reactive wheat antigens increased during wheat seed maturation. Wheat cultivars could be identified in which the expression of certain IgE- and IgA-reactive components was strongly reduced or not detectable.
Conclusions: The expression of IgE- and IgA-reactive antigens depends on wheat seed maturation and varies in different wheat cultivars.

Weeds are one of the major constraints for wheat productivity, causing significant yield losses worldwide. While chemical control is the most used practice to overcome weed damage, its efficacy is challenged by increasing weed resistance to most used herbicides, which is an expanding phenomenon caused by herbicide overuse/misuse. Modern wheat varieties are less able to perceive the presence of weeds than old varieties and are therefore less competitive against them and require chemical control to ensure adequate yields.

However, in the absence of a well-organized formal seed system, public research institutions have continued to promote and disseminate improved sorghum varieties to encourage adoption. On the other hand, the lack of evidence on smallholder farmers' demand for improved varieties has discouraged the seed industry from investing in marginalized crops, like sorghum, in contrast to more commercialized crops such as wheat and maize.

Prothioconazole (Prot) has been widely used for over two decades in controlling cereal diseases. However, the continuous emergence of resistance in plant pathogens has necessitated the development of novel fungicides. Thiosulfonate compounds have great application prospects due to their unique structural features and multisite activity.

Introduction: The autogamous nature of wheat presents a significant challenge for hybrid wheat breeding, which relies on cross-pollination. To facilitate hybrid wheat production, it is essential to modify the floral morphology of wheat to promote outbreeding rather than inbreeding. While some genetic diversity for flower morphology exists within wheat, it is limited compared to the vast and largely untapped genetic variation found in its wild relatives for potentially all agronomically important traits, including flowering characteristics.

Gene expression of developing seeds drives essential processes such as nutrient storage, stress tolerance and germination. However, the spatial organisation of gene expression within the complex structure of the seed remains largely unexplored. Here we report the use of the STOmics spatial transcriptomics platform to visualise spatial expression patterns in the wheat (Triticum aestivum) seed at the critical period of grain filling in mid-seed development.
