Summary: The purpose of this study is to explain the reasons for the difference in seed dormancy between wild and cultivated barley. Results showed that wild barley exhibited deep dormancy when germinated at 28°C, which may be due to low water content, slow water absorption, lower soluble protein, MDA content and ion leakage. The deep dormancy of wild barley could be broken by 1°C through increasing antioxidative enzyme activity, elevating seed germination-promoting phytohormones (JA, TZ, TZR) and decreasing seed germination-inhibiting phytohormones (ABA, IAA, SA) in cultivated barley. The genetic variance in genes related to phytohormone metabolism and antioxidative enzymes between wild and cultivated barley may be responsible for the germination difference.

Summary: Barley, a major crop globally, has been genetically improved for higher yields but weakened in resilience to adverse environments. Climate change demands crop varieties that can grow under stress conditions, where wild varieties and landraces may play a crucial role.

Summary: This study investigated the genetic control of barley peduncle morphology and identified three major QTL regions on chromosomes 2H and 3H impacting peduncle traits. The exotic allele at the QTL on chromosome 3H improved all three investigated traits, showing potential for enhancing plant stability and straw biomass production.

Summary: The objective of this study was to evaluate the interaction between plants and nano-Cu under Cu deficiency. Nano-Cu and CuSO4 were applied to Hordeum vulgare L. to examine their effects on plant leaves. The analysis of Cu compounds-plant leaves interactions was conducted using spectroscopic and microscopic methods. The effects of Cu compounds on plant traits were determined after 1 and 7 days of exposure. The results showed that nano-Cu had a lower Cu content compared to CuSO4, and the changes in biochemical traits were mostly observed after 1 day. CuSO4 exposure induced oxidative stress, while nano-Cu at 100 mg L-1 demonstrated enhanced stress tolerance. Overall, nano-Cu showed promising effects on plant health.

Summary: In this study, genomic regions linked to resistance against barley leaf rust were identified using genome-wide association study, and novel loci were discovered. The resistant barley genotypes and SNP markers identified in this study can be utilized for accelerated selection and pyramiding of leaf rust resistance genes in North African barley germplasm.

Summary: The effect of sodium chloride (NaCl) on cadmium (Cd) tolerance, uptake, translocation, and compartmentation in barley was studied. NaCl did not significantly affect plant development and biomass production, but Cd alone reduced plant development rate and biomass production. NaCl addition accentuated the Cd effect on plant growth. NaCl limited Cd accumulation in the roots and shoots by reducing Cd-absorption efficiency and translocation. However, NaCl increased Cd toxicity and limited plant yield.

Summary: This study used high-resolution mass spectrometry to analyze the development of barley anthers, identifying over 6100 non-redundant proteins including 82 known and putative meiotic proteins. Although protein abundance was relatively stable throughout prophase I, dynamic variations in 336 proteins were quantified. This research provides new insights into the development of the male reproductive organ in small grain cereals during meiotic prophase I.

Summary: WHIRLY1 proteins in barley and maize compact plastid nucleoids in Escherichia coli cells, while WHIRLY1 proteins in Arabidopsis and potato, as well as WHIRLY2 proteins, do not have the same impact. Mutagenesis of HvWHIRLY1 revealed that a specific motif is responsible for the nucleoid compacting activity in bacteria. This suggests that WHIRLY1 proteins in different plant species can have diverse functions in nucleoid compaction due to sequence variation.

Summary: Rapid population growth and climate change pose challenges to global crop production, prompting plant breeders to seek ways to enhance adaptation and sustainability. This study focuses on the genetic basis of bulb formation in Hordeum bulbosum, a perennial species related to barley. Through evolutionary conservation analysis and differential expression analysis, candidate genes involved in bulb formation and flowering regulation were identified. A molecular model for the regulation of bulb formation involving storage organ development and starch biosynthesis genes was proposed. The high conservation between H. bulbosum and barley suggests the potential for biotechnological applications to accelerate breeding towards perenniality in barley.

Summary: The experiment showed that leaching of 1,2,4-triazole from barley seeds coated with triazole fungicides is a possibility, but only a small percentage of the fungicides ended up as 1,2,4-triazole in the leachate. Therefore, when evaluating the leaching risks from pesticide applications in agriculture, both seed dressing pesticides and their degradation products should be taken into consideration.

Summary: A genome-wide association study identified a Laccase gene that is crucial for successful seed germination after submergence and recovery in a large barley panel. Flooding events caused by global climate change have a significant impact on crop production. Sensitive barley varieties exhibit underwater secondary dormancy due to lower oxygen permeability, which can be eliminated by nitric oxide donors. The discovery of the differently regulated Laccase gene in grain development provides insights for improving barley genetics and enhancing seed germination after short-term flooding.

Summary: The impacts of plastic particles, especially in agro-ecosystem, are being extensively studied. In a simulation experiment, elevated atmospheric CO2 concentration increased nanoplastics concentration in NPs-treated roots. Furthermore, elevated CO2 concentration decreased H2O2 concentrations in NPs-treated leaves and roots by intervening antioxidant enzymes. In NPs-treated plants, elevated CO2 concentration increased P-n, C-i, and carotenoid concentration, while decreased g(s) and T-r. These findings provide insights into the eco-physiological response of barley plants to NPs under future agricultural sustainability.
