Summary: Beneficial plant-associated soil microbes can enhance plant tolerance to stress and nutrient uptake, but their benefits can be influenced by above-ground stressors like herbivores and pathogens. This study found that soil rhizobia decreased aphid abundance and virus titre on host plants, while also affecting gene expression related to plant defense and hormone signaling.Mutually antagonistic plant-mediated interactions among soil microbes and above-ground stressors can affect plant susceptibility and herbivore nutrient uptake, indicating the variability of soil microbe and above-ground stressor effects on plant health based on multi-trophic plant-mediated interactions.

Summary: This study aimed to investigate the effect of applying growth regulators on wheat yield under different fertility conditions. The results showed that applying 150% recommended dose of fertilizer along with 15 t/ha organic manure significantly increased wheat yield and nitrogen, phosphorus, and potassium uptake. Additionally, applying tebuconazole significantly increased yield, while the effect of chlormequat chloride was not significant.

Summary: In this study, Bacillus amyloliquefaciens Ba13 was found to significantly promote the growth of tomato plants and exhibit antagonistic activity against a variety of plant pathogens. The genome of strain Ba13 encodes various antibiotics and volatile compounds, as well as the ability to synthesize plant hormones through different pathways. These findings suggest that Ba13 has the potential to be used as a microbial agent for promoting plant growth and controlling plant diseases.

Summary: Frequent and improper use of herbicides disrupts plant metabolism, decreases crop quality, and affects soil microbial community. This study investigated the inhibitory effects of six herbicides on soil microbial community, hormone levels, and secondary metabolites in wheat seedlings. The results showed that certain herbicides induced oxidative damage, reduced phytohormones and secondary metabolites, and decreased microbial abundance.

Summary: Growth conditions and conservative economic traits play important roles in improving biomass production and N stress tolerance of wheat plants. Understanding the relationships between different plant functional traits is crucial for studying ecosystem composition and function. This study found that more conservative leaf and root economic traits are beneficial for wheat plants under limited N supply, suggesting their potential as targets for wheat breeding programs.

Summary: In this study, the role of sRNA-mediated gene regulation in mycoparasitic interactions was investigated by performing sRNA and degradome tag sequencing of the mycoparasitic fungus Clonostachys rosea interacting with the plant-pathogenic mycohosts Botrytis cinerea and Fusarium graminearum. The majority of differentially expressed sRNAs were downregulated during the interactions with the mycohosts compared to a C. rosea self-interaction control, thus allowing desuppression of mycohost-responsive genes. Degradome analysis showed a positive correlation between high degradome counts and antisense sRNA mapping and led to the identification of 201 sRNA-mediated potential gene targets for 282 differentially expressed sRNAs. The study expands the understanding of sRNA in regulating interspecific fungal interactions and mycoparasitism.

Summary: Based on a long-term tillage experiment, it was found that non-inversion tillage can increase fungal denitrification activity in the upper soil layers, while reducing tillage intensity can increase the genetic potential for fungal denitrification. Different tillage regimes select for fungal denitrifiers with different functional capabilities and lifestyles, mainly by altering carbon and nitrogen related niches.

Summary: Sustainable food production requires agriculture to conserve biodiversity and facilitate ecosystem services while reducing inputs detrimental to ecosystem functioning. Legume intercropping shows promise in increasing vegetation diversity within fields and facilitating cropping system multi-functionality. However, the effects of intercropping on biodiversity-mediated ecosystem services such as pollination or natural pest control are not well understood.

Summary: Heavy metal pollution has significant effects on ecosystem nitrogen cycling. This study investigated the effects of copper on microbial guilds and plant responses in two different grassland soils. The results showed that higher copper treatments resulted in lower microbial abundances, potential ammonia oxidation rates, and plant biomass. Additionally, plants had increased nitrogen content and enriched shoot nitrogen isotope with higher copper concentrations.

Summary: A study in Sweden found that wildfires in boreal forests have a greater impact on belowground communities than on vegetation composition. Severe fires resulted in tree mortality and destruction of soil organic matter, affecting the regeneration of vegetation and diversity of soil biota. Soil-related fire severity had less impact on vegetation composition, fungal communities, and soil animals.

Summary: This study analyzed 60 mitochondrial genomes of five necrotrophic fungal pathogens on conifers and found low genomic and genetic variation but multiple rearrangements in the complex. Additionally, several shared genes and sequences were discovered. Within-species variation was very low, indicating a slow evolution of the mitochondrial genome in this fungal complex.

Summary: This study evaluated the resistance of six new back-crossed pea breeding lines derived from the cross between the susceptible commercial cultivar Linnea and the landrace PI180693 against Aphanomyces euteiches and Phytophthora pisi. The resistance of these lines was assessed in growth chamber, green house, and field trials. The results showed that the resistance from PI180693 interacted with the virulence levels of A. euteiches and was less effective against root rot caused by P. pisi. However, the breeding lines performed well in commercial production traits, indicating their potential use in commercial breeding programs.

Summary: A survey was conducted in Sweden to investigate the parasitism of terrestrial slugs by helminths. It was found that 13% of the collected slugs were infected, with the highest parasitism rate in autumn and a higher likelihood of parasitism in Arion vulgaris compared to native slug species. The dominant helminth species identified were Alloionema appendiculatum and Brachylaima thompsoni, which are reported in Sweden for the first time.
