Summary: Elevated CO2 concentration and changes in precipitation patterns have complex effects on plant growth and physiology. This study examined the impacts of elevated CO2 and drought stress on the growth and physiology of P. atlantica seedlings. The results showed that elevated CO2 increased various growth parameters and improved water status, while reducing oxidative stress. Drought stress had negative effects on growth, but these effects were mitigated by elevated CO2. These findings suggest that increased CO2 may help alleviate the negative effects of drought on P. atlantica trees in natural conditions.

Summary: This study investigates N2O production pathways in Australian forest soils and finds that temperate soils have the highest N2O emission rate, predominantly from the organic nitrogen pool, while arid soils contribute most significantly. Furthermore, the potential N2O emission from heterotrophic nitrification is negatively related to latitude, and the contribution of organic nitrogen to N2O production is negatively correlated with soil total nitrogen and carbon content.

Summary: This study explored the effects of precipitation changes and common land use practices on soil respiration in grasslands. The results showed that altered precipitation had a stronger impact on both abiotic and biotic drivers compared to land use practices, resulting in a greater impact on soil respiration and its components. The experiment found that reduced precipitation led to a decrease in soil respiration, while increased precipitation led to an increase. Grazing and mowing had relatively smaller negative effects on soil respiration compared to fencing, but the interactive effects of land use and precipitation further influenced soil respiration.

Summary: Cropland is a major contributor to nitrogen pollution, and reducing this pollution is a challenge due to the decentralized nature of the pollution and the limitations in implementing pollution-reduction measures. By analyzing field observations, we have identified key measures that can significantly reduce nitrogen losses from croplands while improving crop yield and nitrogen use efficiency. Implementing these measures on a global scale could lead to significant benefits in food supply, human health, ecosystems, and climate, with relatively low mitigation costs.

Summary: This study compared the effects of continuous versus rotational grazing and low versus high mowing frequencies on grassland ecosystems in Inner Mongolia. It found that grazing intensity significantly decreased plant community height and biomass, as well as decreased shoot carbon concentration but increased nitrogen and phosphorus concentrations. However, mowing had no significant effect on these parameters. The study also found that grazing significantly decreased aboveground carbon, nitrogen, and phosphorus pools, while mowing had no significant effect on these pools. The concentrations of carbon, nitrogen, and phosphorus in plant roots showed little response to grazing or mowing regimes.

Summary: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.
