Summary: Barley is a globally significant crop with various uses, but its productivity is limited by multiple stresses. Crop wild relatives, especially Hordeum vulgare ssp. spontaneum and H. bulbosum, are important genetic resources for developing new varieties. In experiments, some wild barley accessions showed resistance to multiple diseases, but no lines performed better in terms of yield than the best checks. Further efforts are needed to strengthen pre-breeding work, evaluate more wild Hordeum accessions, and select elite germplasm for barley breeding programs.

Summary: Plants respond to drought by reprogramming gene expression with the help of the phytohormone abscisic acid (ABA). This study investigated the response of barley plants to drought at both the epigenome and transcriptome levels. It was found that specific genes involved in ABA signaling and related pathways were induced in response to drought, including two members of the PP2C family. Histone modifications, such as H3K9 acetylation, were also found to be more sensitive to drought compared to H3K4 trimethylation.

Summary: In this study, drought response in four varieties of barley was investigated. The varieties showed different critical soil water contents (SWC), and pathways related to drought and salinity response were upregulated while growth and development pathways were downregulated during drought. During recovery, growth and development pathways were upregulated, while autophagy-related genes were downregulated. The findings suggest adaptation to distinct rainfall patterns and provide insights into new genes associated with drought response in barley.

Summary: This study aimed to screen drought stress tolerance in Moroccan barley cultivars. Physiological and biochemical parameters were measured to evaluate the drought tolerance. The results showed that drought stress reduced relative water content, shoot dry weight, and chlorophyll content, but increased electrolyte leakage, hydrogen peroxide, malondialdehyde, water-soluble carbohydrates, soluble protein contents, as well as catalase and ascorbate peroxidase activities. 'Firdaws','Laanaceur', 'Massine', 'Taffa', and 'Oussama' exhibited higher levels of shoot dry weight, relative water content, catalase, and ascorbate peroxidase activities, indicating strong drought tolerance. On the other hand, 'Adrar', 'Amalou', 'Amira', and 'Tamellalt' showed higher values of malondialdehyde and hydrogen peroxide content, suggesting drought sensitivity.

Summary: A comparison between modern and wild barley cultivars revealed that modern cultivars have improved defense responses in roots compared to wild genotypes, indicating the impact of agronomic selection and domestication. The differences between the two groups are largely associated with phenotypic adaptions, particularly in plant biomass. In one modern cultivar, the expression of defense-related genes, such as PR1 and PR5, was significantly upregulated in root tissues when challenged with R. solani. These findings have implications for understanding soil-root rhizosphere interactions and breeding disease resistance.

Summary: This study demonstrated the potential of high-throughput hyperspectral imaging to accurately predict leaf concentration of 15 mineral nutrients in barley. Specific patterns of variation in leaf nutrient concentration between developmental stages were observed, and quantitative trait loci associated with the simultaneous expression of leaf nutrients were detected, suggesting potential co-regulation in barley. The findings provide a new approach for nutrient assessment in large-scale field experiments to support plant biofortification through gene and genotype selection.

Summary: The genetic diversity of Ethiopian barley, influenced by diverse topography, altitude, climate conditions, soil types, and farming systems, was analyzed. Three genetically distinct clusters were identified, with higher genetic variation within clusters and moderate genetic differentiation between clusters. The weak correlation between geographic distance and genetic differentiation was observed, but certain regions showed a significant association between landraces and genetic clusters.

Summary: Tillering, an important trait in cereal crops, has been extensively studied in rice and wheat, but research on barley is limited. This review utilizes bioinformatics to map barley tiller development genes and discusses their regulation at genetic, physiological, and environmental levels. The study also establishes a novel link between phytohormones, sugars, and tillering. It provides evidence on how environmental cues and cropping systems optimize tiller number. This comprehensive review enhances understanding of barley's genetic and physiological mechanisms controlling tillering and other developmental traits.

Summary: This study analyzed the genetic control of root system architecture in a winter wheat population under different nitrogen treatments. The research found that 60 quantitative trait loci were specific to nitrogen treatments. Additionally, this study revealed a disparity in the genetic control of root development under low and high nitrogen supply, suggesting the need for targeted gene selection in breeding wheat varieties with improved nitrogen uptake efficiency.

Summary: The multi-parent-advanced-generation-intercross population WM-800 was developed to enhance genetic diversity in wheat breeding. WM-800 lines showed significant differences between treatments and high heritabilities for agronomic traits. GWAS based on haplotypes identified multiple QTL associated with grain yield and other traits. A novel QTL on chromosome 2B exhibited pleiotropic effects on multiple yield components, possibly mediated by a nitrate transporter gene.

Summary: To understand the natural variation of nitrogen uptake efficiency (UPE), a winter wheat population was phenotyped under different nitrogen levels and analyzed using a genome-wide association study. A total of 543 QTL related to nitrogen were identified, with 42 stable QTL detected across multiple weeks. Candidate genes associated with gibberellic acid-regulated growth and nitrate transporters were also identified. The results suggest that selection for UPE is beneficial under nitrogen-limited conditions.
