Summary: Biodiversity and ecosystem functioning (BEF) are often positively correlated, but the impact of soil biodiversity on plant performance is still not well understood. This study manipulated microbiome predatory protist diversity to investigate its effect on plant biomass, and found that the relationship between soil biodiversity and plant biomass is context-dependent. Positive soil BEF relationships may not be the norm and should be evaluated in a context-dependent manner.

Summary: Dry matter accumulation and partitioning in maize were studied under drought stress and rewatering conditions. The results showed that reproductive organs were more sensitive to drought and their dry matter accumulation was affected even after rehydration. Drought during vegetative growth reduced stalk dry matter more than leaves, while drought during reproductive growth significantly decreased leaf dry matter. Drought increased the dry matter partitioning rates of vegetative organs and decreased the partitioning rates of ears, leading to reduced harvest index. The persistence of drought impact depended on the occurrence stage and degree of drought, as well as the duration of rewatering.

Summary: Moderate drought stress had positive effects on the morphological and physiological parameters of licorice, making it the most suitable water regime for cultivation. Plant growth under moderate water deficit was slightly higher compared to well-watered conditions, promoting licorice growth, root yield, and secondary metabolite production. Further drought intensification led to a decline in secondary metabolites, indicating the importance of finding a balance in water management for licorice cultivation in arid regions.

Summary: Numerous studies have shown that a larger root biomass is associated with increased above-ground biomass under limited water supply, and this relationship is influenced by genetic control and environmental factors. This study analyzes the relationship between shoot and root biomass in bread wheat and its wild relatives using a large dataset. The results show a positive correlation between shoot and root biomass, with the correlation values increasing over time. Further analysis suggests that increasing root biomass beyond a certain point may negatively impact shoot biomass. The study also highlights the different responses of two wheat cultivars to water availability scenarios, emphasizing the need to breed wheat varieties for specific environmental challenges.

Summary: Studies have shown that tree species have a significant impact on soil organic carbon stocks and carbon distribution. However, the underlying mechanisms, including the roles of litter traits, soil properties, and microbiome, are not fully understood. This study examined the effect of six common European tree species on the quality and nutrient availability of soil organic matter as perceived by microbial communities, and explored the links between soil enzyme activities, microbial resource limitation, and SOC stocks. The results suggest that tree species-mediated enzyme activities, microbial resource limitation, and microbial community composition are important drivers of SOC stocks and vertical distribution among tree species and associated mycorrhiza types.

Summary: Shrubland ecosystems in Europe are under threat from climate change. The INCREASE project conducted experiments on six shrubland ecosystems across Europe to investigate the effects of nighttime warming and drought on CO2 fluxes. The study found that gross primary productivity (GPP) was more sensitive to drought and warming than ecosystem respiration (Reco), and GPP was the main contributor to changes in net ecosystem exchange (NEE). The response of NEE to drought and warming varied along the climate gradient, with northern sites showing a neutral to positive response due to seasonal rewetting. The study also highlighted the importance of site-specific factors, such as growing season periods and plant species composition, in influencing the overall response pattern of CO2 fluxes.
