Summary: Our study shows that only the rye-derived centromere part in the wheat-rye 1BL/1RS translocation chromosome incorporates wheat CENH3, supporting the idea that one centromere part undergoes inactivation in a translocated chromosome to maintain chromosome stability.

Summary: Understanding the genes controlling root development is crucial for engineering root systems adapted to different soil types. In wheat, the 1RS.1BL wheat-rye translocation is associated with improved drought tolerance and a large root system. However, a mutant line carrying an interstitial segment of wheat chromosome arm 1BS in the distal region of the 1RS arm showed reduced grain yield and shorter roots. The study found that the dosage of duplicated 1RS genes is critical for seminal root length, emphasizing the importance of gene dosage in root development.

Summary: Studying the effect of different subtelomeric tandem repeat compositions on the meiotic recombination of 1RS arms can enrich the genetic diversity of 1BL.1RS translocation chromosomes. Using oligonucleotide probes, it was observed that the variation in the pSc200 tandem repeat affected the meiotic recombination rate of 1RS arms. The subtelomeric structure of 1RS can affect its recombination and the localization of genes on 1RS through meiotic recombination.

Summary: The wheat-rye translocations from 'Petkus' rye have contributed significantly to wheat production worldwide. However, the resistance genes on these translocations have lost their effectiveness against new pathogens. In this study, new translocation lines with high resistance to stripe rust were developed by crossing rye with wheat. A new gene, named YrRt1054, was identified in these lines and showed resistance to some virulent stripe rust pathotypes. This study suggests that rye cultivars could be valuable sources of untapped resistance variation.

Summary: The study developed an interfering expression vector targeting omega-secalin genes and generated transgenic wheat lines using the T1BL.1RS translocation. Two representative transgenic lines showed significant changes in protein content compared to controls, with varying effects on bread and cake quality. The study highlights the impact of vector promoter in RNA interference and the potential variability in wheat processing quality caused by the same RNAi construct.

Summary: This study investigated the cytological and genetic effects of rye chromosomes 1RS and 3R on wheat through fluorescence/genomic in situ hybridization and quantitative trait locus analyses. The results showed that the recombination of chromosomes 1BS and 3D from the wheat parent was inhibited by 1RS and 3R. While 1RS had no effect on yield-related traits, 3R was significantly associated with white seed coats and decreased yield-related traits, but had no effect on stripe rust resistance.

Summary: The study identified new organizations of subtelomeric tandem repeats on 1RS, reflecting new genetic variations. These 1RS arms may contain abundant allelic diversity for agricultural traits. The narrow genetic base of 1RS arms in 1BL.1RS and 1AL.1RS translocations is currently restricting their use in wheat breeding programs.

Summary: This study used marker-assisted backcross selection to introgress a distal rye region with superior root traits into the wheat cultivar HD2967, resulting in derivatives with higher root biomass, yield, and drought resistance. Additionally, rust resistance was introgressed into the derivatives in the second backcross, leading to significant improvements in overall crop performance.

Summary: This study reveals that dosage differences in monocot-specific 12-OXOPHYTODIENOATE REDUCTASE genes play a crucial role in shaping root architecture in wheat. Increasing the dosage or introducing these genes through transgenic methods results in inhibition of root development, early lateral root growth, and elevated levels of jasmonic acid (JA and JA-Ile). The findings suggest that jasmonic acid is involved in regulating root length differences. These OPRIII genes can be used as a starting point for engineering root architecture in wheat and other cereals.

Summary: This study investigated the fine centromere structure of wheat-rye translocation chromosomes, revealing that only the rye-derived centromere is functional, while the wheat-derived centromere is inactive. The rye-derived centromere is enriched with specific retrotransposons and stable non-B DNA structures, contributing to its functionality. On the other hand, the wheat-derived centromere shows high levels of DNA methylation and H3K9me2, suggesting its role in maintaining the inactive status.

Summary: Wheat-rye translocations 1RS.1BL and 1RS.1AL are widely used in bread wheat breeding worldwide due to their advantages in disease resistance, pest resistance and performance under drought-stress conditions. However, these translocations are only found in experimental lines of durum wheat genotypes, despite their potential benefits.

Summary: A new powdery mildew resistance gene, PmBN418, was identified on a 1BL.1RS translocation segment in Bainong 418, potentially offering a valuable resource for wheat breeding. Distorted segregation and preferential transmission of translocation segments were observed in Bainong 418 and CI 17884, highlighting the importance of marker-assisted introgression for incorporating PmBN418 into locally adapted wheat cultivars.

Summary: A novel translocation line D27 was developed by crossing common wheat and Mexico Rye, which had a karyotype of 2n=42=21 II and lacked the 1DS chromosome but had the 1RS chromosome from Mexico Rye. D27 showed promising potential in agronomic traits and dough properties, making it valuable for wheat breeding and studying the genetic diversity of the rye 1RS chromosome.

Summary: The knowledge of genetic diversity of Puccinia triticina in Iran is limited. Through genetic analysis of 175 isolates sampled from wheat and other grasses in 14 provinces of Iran, it was found that SSRs were more effective in differentiating P. triticina populations than ISSRs. The isolates were separated into three large groups, each including isolates from diverse geographic origins and hosts. The results of SSR analysis were consistent with the Bayesian approach, and clonal reproduction prevailed over sexual reproduction of the pathogen in Iran.

Summary: This study evaluated the resistance of 34 Aegilops triuncialis accessions against seven Puccinia triticina pathotypes and analyzed the expression of resistance-associated genes at the seedling stage. Two accessions with contrasting resistance were studied for the expression profile of genes related to PR proteins, phenylalanine ammonia-lyase, and ATP-binding cassette transporter. The results showed that some accessions exhibited high infection types against certain pathotypes, while others showed strong resistance against all pathotypes. The expression of PR genes was significantly higher in the incompatible interaction compared to the compatible interaction. The study identified potentially new sources of resistance in this Ae. triuncialis population.
