Summary: This study investigated the transcriptional and metabolic responses in Brachypodium distachyon roots following challenge with Fusarium graminearum. It was found that Bd roots recognized encroaching Fg prior to physical contact by altering gene expression and secretion of host metabolites, resulting in increased resistance to the pathogen.

Summary: The study found that S-metolachlor inhibits wheat seedling growth and reduces the richness of rhizosphere microbiome, while increasing the abundance of certain beneficial bacteria. This suggests that plants recruit potential beneficial microorganisms to resist the stress induced by S-ME.

Summary: Plant-soil feedbacks mediated by benzoxazinoids (BXs) were found to affect maize growth and insect resistance conservatively in two arable soils, but not in a more fertile grassland soil, indicating a soil-type dependence. Wheat also responded to BX-feedbacks, showing a negative growth response conserved between cereals, while insect resistance exhibited opposite patterns. Cultivar-specificity of BX-feedbacks was a key finding, suggesting the potential to optimize crops to avoid negative plant-soil feedbacks in rotations.

Summary: Bacillus strains BMH and INV, closely related to Bacillus velezensis, individually reduced the number of galls and eggs of M. incognita by more than 90% in tomato roots. However, when combined (BMH + INV), the suppression of RKN and tomato growth was lower compared to single-strain applications.

Summary: Fungal volatile organic compounds (VOCs), particularly 1-Octen-3-ol, are highly toxic to root-knot nematodes and show potential as ecofriendly alternatives to synthetic nematicides. Exposure to 1-Octen-3-ol and 3-Octanone resulted in high mortality rates of the nematodes, with 1-Octen-3-ol exhibiting greater nematicidal activity than 3-Octanone.

Summary: Infections of plants with fungi can result in diverse outcomes, from symptom-less resistance to severe disease and death. Research has identified genes responsible for plant resistance or susceptibility, many of which code for receptors that recognize pathogen invasion. Approaches based on cell biology and phytochemistry have helped to identify factors that prevent invasive fungal pathogens from penetrating plant cells.

Summary: Terrestrial plants can influence the recruitment of rhizosphere microbiome in adjacent plants through root exudates, potentially affecting their growth and health. This study demonstrated that intercropping with potatoonion can create a disease-suppressive rhizosphere microbiome that protects tomato plants against Verticillium wilt disease. The root exudates from potatoonion promoted the colonization of Bacillus sp., which inhibited the growth of the pathogen and induced resistance in tomato plants.

Summary: This study explored the impact of root exudates variation on AM fungal associations and plant performance in introduced and native populations of an invasive plant. Results showed that introduced populations had higher concentrations of quercetin in root exudates, leading to greater AM fungal colonization and higher plant biomass. Root exudate chemicals, particularly quercetin, played a crucial role in stimulating AM fungal associations in invasive plants.

Summary: Although there is currently little evidence for negative allelopathic effects of Epichloe, our meta-analysis identified several research gaps. Experiments testing the functional belowground effects of Epichloe presence may help to determine its effects on non-host plant performance via plant-soil feedbacks.

Summary: The study found that there are differences in microbial community composition between organic and conventional managed fields. Fungal diversity in organic fields increased over time, but this effect disappeared when conventional paired fields were included in the analysis. The study also showed a relationship between pH and soil organic matter content and the diversity and community composition of bacteria and fungi.

Summary: This study evaluated the effects of different pesticides on soil carbon cycling related enzymatic activities and absolute abundance of functional genes, as well as the changes in cellulolytic and chitinolytic microorganisms and the total microbial community composition. The results suggest that pesticide application may have a negative impact on soil carbon cycle and the stability of soil organic matter and structure.

Summary: Climate warming is a serious anthropogenic stress on the environment, exacerbating the harmful effects of other threats and potentially threatening species preservation and ecosystem services provided by biodiversity. Insects, as central components of many ecosystems, are highly affected by climate change, with effects on physiology, behavior, distribution, and interactions, as well as extreme events.

Summary: Currently, there are few regulations on the discharge of antibiotics from wastewater treatment plants (WWTP), resulting in surface waters becoming a potential reservoir for antibiotics and antibiotic resistance genes (ARGs). In this study, the abundance of indicator genes and ARGs were monitored in a river system from its pristine source to WWTP-impacted water. The results showed that the WWTP effluent is the main source of sulfonamides and indicator genes, but downstream water quality improved with lower sulfonamide concentrations and decreasing abundances of sul1 and sul2.

Summary: Climate changes are causing grapes to mature faster in many regions, but higher temperatures can lead to unbalanced wines. A study tested the use of crop forcing in delaying the maturation of 'Touriga Nacional' vines in the Douro Region. Results showed that while crop forcing delayed ripening, it also severely impacted grape production. However, it did result in berries with lower pH, higher acidity, and increased phenolic content, potentially improving wine quality.

Summary: This study aims to investigate the role of protein farnesylation in plant responses to nitrogen by studying the metabolic and phenotypic adaptations of the era1.8 mutant to different NH4NO3 supplies. The results show that era1.8 exhibits exacerbated responses to nitrogen starvation, with increased root/shoot ratio, anthocyanins content, and carbon/nitrogen ratio. Transcriptomic analysis reveals the over-expression of genes related to nitrogen starvation adaptation and identifies two genes encoding uncharacterized farnesylated proteins. Overall, the study highlights the involvement of protein farnesylation in plant adaptation to nitrogen nutritional stress.

Summary: Using spatial metabolomics and correlation-based networks, this study investigated how continuous changes in soil features and topography may impact the polyphenol composition in grape canes. The results showed correlations between soil and topographic variables and metabolomic responses. Spatial metabolomics driven by correlation-based networks can be used as a new field-phenotyping tool in precision agriculture.

Summary: This study demonstrates that the cooperation between AMF and N2O-reducing Pseudomonas on hyphae significantly reduces N2O emissions. The presence of AMF enhances the abundance of N2O-reducing bacteria, specifically Pseudomonas, which leads to a decrease in N2O emissions. The organic acids exuded by hyphae not only attract Pseudomonas, but also stimulate the expression of the nosZ gene, promoting N2O reduction.

Summary: Grape berries are a significant source of phenolic compounds, and a practice using biostimulants has been developed to enhance phenolic content. A field experiment was conducted to investigate the effect of benzothiadiazole on polyphenol biosynthesis during grape ripening. The results showed the induction of genes involved in anthocyanins and stilbenoids biosynthesis, leading to increased phenolic compounds in wines from treated grapes.

Summary: Pesticides, such as fipronil, propyzamide, and flutriafol, have long lasting effects on non-target microorganisms. These pesticides affect soil microbial community structure, enzymatic activities, and abundance of key functional genes. Although the microbial community can recover from the pesticide effects, the persistent inhibitory effects on soil enzymatic activities indicate the lack of functional recovery.

Summary: Stilbenoids, important phenylpropanoid compounds synthesized in grapevine in response to stress, have been mainly described in berries. However, this study shows that they can also accumulate in the woody canes during bud burst, and their accumulation is correlated with the increased expression of stilbene synthase genes and the transcription factor VviMYB14. Additionally, there is a general stimulation of the plastidial shikimate pathway.
