Summary: The genomic landscape of recombination in rye individuals was investigated, revealing differences in recombination patterns based on domestication status and geographic origin. Substantial variation in the physical size of low-recombining regions was observed among different subpopulations, with a major QTL identified. Domesticated rye individuals showed differences in recombination landscape but not in crossover frequency. A genomic region associated with the ScESA1 gene in domesticated subpopulations exhibited moderate patterns of selection.

Summary: Rye, an important crop and valuable genetic resource, was found to be domesticated directly from weedy relatives through genomic selection by humans, according to a study analyzing whole-genome resequencing data from worldwide accessions of wild, weedy, and cultivated rye. The study also identified genes associated with important agronomic traits and detected a potential introgression from a wild perennial that could affect grain yield and plant growth in rye.

Summary: The study found that the genetic variation of perennial rye is mainly influenced by specific loci on the chromosomes rather than the presence of chromosomal multivalents. Through QTL mapping, key genetic loci affecting perenniality and fertility were identified.

Summary: This study evaluated the biogas and methane yields from six cereal rye cover crops grown in the Midwest, and found that ensiling can increase methane yield but may disrupt or fail anaerobic digestion at high solid contents.

Summary: The study found that less ergot-susceptible rye cultivars tend to contain lower levels of ergot alkaloids. Genotypes displayed significant variations in pollen shedding, ergot severity, and EA contents, with high heritabilities observed. The correlation between ergot severity and EA contents was strong, suggesting a consistent relationship between the two factors.

Summary: This study developed 166 new primary 1RS.1BL translocation lines by crossing rye varieties with several wheat cultivars. Cytogenetic and molecular analyses confirmed that all of these lines contained a pair of intact 1RS.1BL translocation chromosomes. The effects of the 1RS.1BL translocations from different rye cultivars on resistance to stripe rust varied, and the greatest genetic diversity was observed in translocations derived from diverse rye varieties but in the same wheat background. These diverse translocation lines provide ample opportunities for improving stripe rust resistance in wheat.

Summary: Xyloglucans and homogalacturonans demonstrate developmental stage specificity, while different xylans have tissue specificity in growing rye roots. Mannans, arabinans and galactans are also detected within the protoplast. The distribution of cell wall polysaccharides and their dynamics during elongation growth and histogenesis in rye roots were revised using nonfixed material and the spectrum of antibodies. The study found that rye cell walls at the earliest stages of cell development were enriched with the epitopes of xyloglucans and homogalacturonans, contrary to expectations.

Summary: This study reports on the biochemical, cytochemical, and molecular studies on PR proteins and AGP during the early stages of androgenesis induction in rye breeding lines. The initiation of androgenesis was associated with high activity of beta-1,3-glucanases and chitinases, with some isoforms of beta-1,3-glucanases being anther-specific. Additionally, stress pre-treatments were found to promote AGP accumulation in the androgenesis-responsive rye line.

Summary: Individually mapping stem rust resistance genes within self-incompatible rye populations was successful through utilizing natural diversity and segregating populations. Using a 10 K-SNP chip and cumulative logit models, significant associations between ordinal infection score and marker alleles were found, leading to the validation of resistance-linked markers. This approach provides a competitive alternative to linkage mapping for mapping monogenically inherited seedling resistance genes in genetic resources.

Summary: Rye, with its resistance to low temperatures and poor soils, is being reconsidered as a source of environmentally resilient genes for growing cereals that can withstand global warming. Recent studies show a narrowing genetic diversity in modern rye varieties, making the preservation of local landraces essential for maintaining the genetic heritage of rye. The use of ex situ conservation can help avoid the loss of untapped genetic potential.

Summary: This study explores the origins, domestication traits, and cultivation history of rye, emphasizing the integration of archaeobotanical methods and aDNA sequencing to investigate the impact of cultivation practices, local environmental conditions, and genetic variation on rye diversification. Analyzing plant remains from German Wellerholzer, the research provides insights into cultivation practices, local environment, and genetic diversity of rye through phylogenetic analysis.

Summary: Fifty years ago, Susumu Ohno proposed the C-value paradox, which states that there is no correlation between genome size and organism complexity, and emphasized on genome redundancy. The concept of junk DNA, referring to DNA that does not have a positive effect on organism fitness, remains controversial. Rye is used as a subject to test the validity and scientific significance of this concept. The review analyzes the structural organization of rye chromosomes and discusses the molecular mechanisms and DNA sequences involved in genome size increase during evolution.

Summary: The Schistosoma mansoni venom allergen-like protein (SmVAL) superfamily consists of at least 29 molecules classified into Group 1 and Group 2 based on the presence or absence of signal peptide and conserved cysteine. While Group 1 SmVALs interact with hosts, Group 2 SmVALs are believed to perform parasite-related functions within the schistosome. Experimental evidence supports host interactions for Group 1 SmVALs, but functional roles for Group 2 SmVALs are still unclear. This study provides evidence for an essential function of a Group 2 SmVAL, SmVAL6, in schistosome biology.

Summary: Alpha-galactosidase (α-GAL) and alpha-N-acetylgalactosaminidase (α-NAGAL) are two glycosyl hydrolases responsible for maintaining cellular homeostasis by regulating glycan substrates on proteins and lipids. The parasitic blood fluke Schistosoma mansoni also contains functionally important α-GAL and α-NAGAL proteins, and inhibiting their activities could lead to the development of novel chemotherapeutics. The study identified that Smp_089290 is the only S. mansoni protein containing the necessary amino acids for α-GAL/α-NAGAL substrate cleavage. Inhibition of α-NAGAL activity in the adult worms significantly reduced their motility and egg production. This study contributes to understanding the glycan processing and modification machinery of schistosomes and suggests that targeting α-NAGAL may be a potential strategy for controlling schistosomiasis.

Summary: Polyploidy is a major evolutionary force, but it poses challenges for meiotic chromosome segregation. In this study, we describe the meiosis process in the allopolyploid species Arabidopsis suecica. The meiosis in A. suecica is diploid-like, with some abnormalities observed at low frequency, but no evidence of crossover formation between non-homologous chromosomes.
