Using gliadins, endosperm storage proteins of kernels, as markers, the genetic diversity of 170 samples from the Triticum spelta L. collection of the Vavilov Institute of Plant Industry was studied. High intraspecific polymorphism of the gliadin electrophoretic patterns was revealed. On the basis of similarity of the gliadin electrophoretic patterns, groups of samples were isolated, and the genetic structurization of the collection was performed.

It is crucial to elucidate the impact of climate change on wheat production in China. This article provides a review of the current climate change scenario and its effects on wheat cultivation in China, along with an examination of potential future impacts and possible response strategies. Against the backdrop of climate change, several key trends emerge: increasing temperature during the wheat growing season, raising precipitation, elevated CO concentration, and diminished radiation.

Unlabelled: Pre-harvest sprouting (PHS) of wheat ( L.) is one of the complex traits that result in rainfall-dependent reductions in grain production and quality worldwide. Breeding new varieties and germplasm with PHS resistance is of great importance to reduce this problem.

Identifying the regulatory effects of noncoding variants presents a significant challenge. Recently, the accumulation of epigenomic profiling data in wheat has provided an opportunity to model the functional impacts of these variants. In this study, we introduce Language of Genome for Wheat (LOGOWheat), a deep learning-based tool designed to predict the regulatory effects of noncoding variants in wheat.

The agronomical interest of hybrid wheat has long been a matter of debate. Compared to maize where hybrids have been successfully grown for decades, the mixed results obtained in wheat have been attributed at least partially to the lack of heterotic groups. The wheat genome is known to be strongly partitioned and characterized by numerous presence/absence variations and alien introgressions which have not been thoroughly considered in hybrid breeding.

Polyphenolic plant compounds possess nutritional and pro-healthy potential, reducing the risk of auto-inflammatory and neoplastic diseases. However, their interference with the progression of thyroid gland dysfunctions has remained largely unaddressed. For this purpose, we combined the analyses of phenolic content and antioxidative activity with the thyroid peroxidase (TPO), lipoxygenase (LOX), xanthine oxidase (XO) and cyclooxygenase-2 (COX-2) activity assays, isobolographic approach and the estimation of thyroid cancer cells' proliferation and motility in vitro.
