Summary: The study found significant differences between tetraploid and diploid barley in terms of morphology, photosynthetic physiology, and transcriptome, with tetraploid barley exhibiting thicker and heavier leaves, larger stomata or stomatal guard cells, more photosynthetic pigments, and improved photosynthesis. The enhanced photosynthesis in tetraploid barley was confirmed by several photosynthetic parameters, and transcriptional analysis revealed that most differentially expressed genes were upregulated in the tetraploid barley.

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 investigated the genetic and environmental signals that regulate heading date in barley. The results showed that vernalization substantially affected plant traits and antioxidant enzyme activity. The expression of key regulatory flowering genes confirmed their involvement in heading time regulation. These findings contribute to a better understanding of the complex mechanism of barley heading date.

Summary: This study aimed to investigate the plant conditioning effect and mode of action of a plant-based biostimulant used in organic farming. The results showed that the biostimulant, enriched with plant bio-active ingredients encapsulated in nano-scale liposomes, could improve the uptake and delivery of active ingredients, enhancing crop resilience, vitality, and yield. Furthermore, high dosages of the biostimulant induced the upregulation of pathogenesis-related genes and other genes associated with induced resistance, indicating a dose-dependent response.

Summary: This study revealed the effects of drought stress on the photosynthetic characteristics and yield of naked oats. The results showed that drought stress decreased the photosynthetic rate, transpiration rate, and stomatal conductance, while affecting the chlorophyll fluorescence rate and photochemical efficiency. Additionally, drought stress led to a decrease in yield. The photosynthetic rate, stomatal conductance, and transpiration all had significant positive relationships with the yield of naked oats. This study is significant for enhancing the production efficiency of naked oat under drought stress.

Summary: This study investigates the molecular evolution, expression pattern, and physiological functions of 14-3-3 proteins in response to drought stress. The results demonstrate the highly conserved and early evolution of 14-3-3s in green plants and the duplication and expansion of 14-3-3s in angiosperms. The findings also highlight the crucial role of Hv14-3-3s in the rapid stomatal response to drought in barley. This research provides valuable evolutionary and molecular evidence for breeding drought-tolerant crops in a changing global climate.

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: Photosynthesis is an important target for crop improvement, but phenotyping photosynthesis in field-grown crops is challenging. Previous studies have attempted to overcome this challenge by phenotyping excised leaf material in the lab, but the representative nature of these measurements compared to attached leaves has not been demonstrated. In this study, we found limited but important differences in photosynthetic traits between excised and attached leaves in tomato, barley, and maize.

Summary: Plant immunological memory, known as priming, is activated by external stimuli and prepares plants for disease resistance. This study investigated the plant responses to different priming actives, such as salicylic acid and beta-aminobutyric acid, in combination with the plant conditioning agent ELICE Vakcina(& REG;). The results showed strong regulation of defense responses, with both synergistic and antagonistic effects depending on the supplementation.

Summary: This study demonstrates the potential of exogenous melatonin (MT) in mitigating the effects of water deficiency in barley. MT application improves photosynthesis, enzyme activity, membrane stability, and antioxidant activity, while also regulating plant hormone levels. The findings highlight the crucial role of MT in water stress tolerance.

Summary: This review summarizes recent progress in understanding barley's response to nitrogen nutrition, evaluation of nitrogen use efficiency (NUE) or tolerance to low nitrogen, mapping of quantitative trait loci (QTL) and gene cloning associated with improving NUE, and breeding of nitrogen-efficient barley. It also introduces several biotechnological tools that could be used for revealing the molecular mechanisms of NUE or breeding for improving NUE in barley, and discusses the latest research ideas in unraveling the molecular mechanisms of improving NUE in other crops.

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.
