Summary: The study identified three octoploid Trititrigia accessions with good resistances to diseases and pests, possessing 14 alien chromosomes with different structural variations in addition to 42 wheat chromosomes. These resources can be valuable in transferring disease and pest resistance genes from Thinopyrum intermedium to common wheat for breeding purposes.

Summary: Allopolyploidy is a powerful genetic and evolutionary force that combines divergent genomes into a common nucleus. One of its striking features is the ability to generate rapid and saltational biological consequences through 'genome shock'. In this study, we analyzed the changes in genome-wide gene expression under diverse environmental conditions in a synthetic allotetraploid wheat, revealing that allopolyploidy caused large-scale changes in gene expression that were variable across conditions and exacerbated by stresses and chromosomal exchanges. Our results provide new insights into the direct impacts of allopolyploidy on condition-dependent changes in subgenome expression.

Summary: This study assessed greenhouse gas emissions of winter wheat and winter rye in Germany from 1983 to 2019, finding that breeding progress led to increased GHGL but significantly decreased CFP. Rye has lower GHGL and CFP compared to wheat, suggesting its potential for climate change mitigation.

Summary: The genus Causonis serves as a model for exploring different hybridization and polyploidization modes in lineages with contrasting species' distribution ranges. Understanding the specific evolutionary histories and genetic properties of focal species is crucial for conservation strategies.

Summary: Through experimental populations of synthetic allotetraploid wheat, it was found that there is extensive variation in both chromosome number (NCV) and structure (SCV), and these variations have significant impacts on phenotype. The study also reveals the factors influencing meiotic homoeologous chromosome pairing and provides insights into allopolyploid evolution.

Summary: This study investigated the folate bioaccessibility of faba bean, oat, rye, and wheat flours and pastes using a static in vitro digestion model. Results showed that the bioaccessibility of folate varied depending on the food matrices, and factors like digestion, heat treatment, and vitamer distribution affected folate stability and loss during processing and digestion.

Summary: Rye has been used as an important genetic resource in wheat breeding, resulting in significant improvements in disease resistance and agronomic traits. As consumers pay more attention to their dietary choices and the food industry strives to meet their demands, the nutritional aspects of grain crops are becoming more important. The high dietary fiber content in rye, especially arabinoxylan, can bring health benefits and serve as a new target for wheat-rye introgression breeding.

Summary: A set of derived addition lines have been created from Xiaoyan 7430, with the chromosome composition characterized and a novel stripe rust resistance gene identified. Molecular markers and a FISH probe have been developed for identification of derived translocation lines, aiding in the introgression of valuable genes from Th. ponticum into wheat.

Summary: Rye is commonly used in wheat improvement programs to transfer numerous genes for stress resistance and improve agronomic traits, but the transfer of large chromosomal fragments or entire chromosomes often leads to a decrease in end-use quality.

Summary: The study evaluated the effects of scalded and scalded-fermented rye wholemeal flour on the quality and acrylamide formation of semi-wheat-rye bread. Scalding increased the content of fructose, glucose, and maltose, while scalded fermentation increased the concentration of certain amino acids, including GABA. Addition of scalded and scalded-fermented flour influenced bread shape, mass loss, color coordinates, and hardness. Scalded-fermented flour improved bread color, flavor, acceptability, and delayed staling, but resulted in higher acrylamide levels compared to the control.

Summary: Lead (Pb2+) pollution in the soil sub-ecosystem is a growing problem globally, and this study compared the photosynthetic performance and antioxidant capacity of Triticeae cereals (rye, wheat, and triticale) under Pb stress. Triticale showed higher antioxidant capacity, photosynthetic activity, and Pb accumulation compared to rye and wheat. The levels of certain proteins involved in photosynthesis were also different among the three cereals, suggesting different responses to Pb stress. Triticale, therefore, has the potential to be used as a heavy metal-tolerant plant.

Summary: In this study, two wheat-rye derivatives, JS016 and JS110, were developed and identified as T6BS.6RL and T6BS.6BL6RL translocation lines, respectively. These lines were found to possess novel powdery mildew resistance genes and exhibited better agronomic traits compared to the previously reported Pm20 translocation line.

Summary: This research focuses on the expression of FPG and OGG1 genes in barley, wheat, and rye during grain germination. The study found that reactive oxygen species accumulation during seed germination leads to DNA damage, and enzymes like FPG and OGG1 are responsible for repairing this damage. Real-Time PCR analysis revealed significant changes in the expression of FPG and OGG1 genes during germination in all three cereal species. The timing of these expression changes varied among species, but there were no differences in the highest expression levels within each species.

Summary: This study describes a novel synthetic tetraploid triticale with Sr35 stem rust resistance gene, obtained by crossing rye and einkorn wheat. The resulting amphiploids possess a set of 28 chromosomes (14 of Am-genome and 14 of R-genome). Important yield-shaping traits such as thousand-grain weight, plant height, and stem length are higher in this tetraploid triticale compared to parental genotypes and standard hexaploid triticale cultivars. This tetraploid triticale genetic stock can serve as a valuable germplasm for triticale improvement or alternative crop development.

Summary: This study identified several resistance genes for wheat leaf rust, including two adult plant resistance genes (Lr34 and Lr37) and nine seedling resistance genes (Lr1, Lr2a, Lr2b, Lr3ka, Lr10, Lr15, Lr17, Lr18, and Lr26). These findings suggest that the hexaploid breeding lines derived from wheat-Thinopyrum amphiploids could serve as new sources for wheat leaf rust resistance.
