Summary: In this study, two Bacillus strains isolated from honey and a waste of an artisanal tannery were evaluated for their antibacterial activity against enteropathogenic Escherichia coli strains. The results showed that the crude cell-free supernatants of both Bacillus strains exhibited anti-E. coli activities, with the lipopeptide fraction of one strain showing significant inhibition. Analysis using mass spectrometry revealed that surfactin homologues were the most abundant lipopeptides produced by both strains, along with kurstakin, iturin, and fengycin homologues.

Summary: This study identified Bacillus velezensis C16 as a strain with strong antifungal activity against early blight pathogen Alternaria solani. The non-volatile lipopeptides and volatile organic compounds produced by C16 showed significant antagonistic activities on A. solani, leading to structural destruction of hyphae and inhibited conidia germination. High-performance liquid chromatography-mass spectrometry and gas chromatography-mass spectrometry analysis revealed iturins and volatile compounds of C16 exhibit strong antagonistic activity on mycelia, suggesting a synergistic effect to resist early blight in potato.

Summary: The aim of this review is to assess the positive and negative impacts of binary oxide nanoparticles on soybean plants and its rhizosphere. The synthesis methods and their merits and demerits of binary oxide nanoparticles are discussed, along with various characterization techniques for tracking nanoparticles inside soybean. The evaluation of rhizosphere microbial communities and comprehensive discussion on the impacts of binary oxide nanoparticles on different parts of soybean plants are also presented. It is observed that the effects of oxide nanoparticles on soybean, rhizosphere, and bioactive compounds are dose-dependent. Lastly, future research directions on the interactions between binary oxide nanoparticles and soybean plants are suggested.

Summary: Drought stress negatively impacted the growth and biochemical content of soybean, but the genotype AGS383 was minimally affected and exhibited superior traits under drought conditions. This genotype showed healthier root and shoot growth, greater leaf area, higher photosynthesis, and better water absorption and potential compared to other genotypes. It also produced lower levels of proline and malondialdehyde. The heavier grains of AGS383 resulted in higher yield under both normal and drought conditions. Further research is needed to identify the genes responsible for AGS383's adaptation to drought stress.

Summary: Drought stress negatively affects maize survival and development from germination to maturity. It alters morphological, physiological, and biochemical activities in maize plants, significantly impacting metabolic functions, membrane integrity, water relationships, yield, photosynthesis, osmotic adjustment, and pigment content. Mitigation measures include breeding drought-tolerant varieties, genomic applications for enhancing drought tolerance, and the use of rhizobacteria and endophytic bacteria to ensure optimal maize productivity.

Summary: The study investigates the stability of plant and soil microbial community in response to nitrogen (N) deposition. The researchers conducted a long-term field trial in a semiarid steppe, examining resistance and resilience of plants and microbes to N addition. The results show that plant resistance is negatively correlated with N application rate, while microbial resistance is independent of N rate. Mowing reduces plant resistance and resilience, but improves soil microbial resilience. This study provides important insights into the resistance-resilience relationship and offers a theoretical basis for the conservation of semiarid steppe.

Summary: Over the years, the use of synthetic pesticides has improved crop yield, but it has also caused significant harm to aquatic life, human health, and the environment. This has led to the exploration and development of organic pesticides (biopesticides) sourced from microbes, plants, and biological nanoparticles as alternatives. Microbial pesticides are specific, affordable, and sustainable, while phytopesticides have various mechanisms of action and minimal risks. Nanobiopesticides have high efficacy, controlled release, and environmental compatibility. This review discusses the different types of pesticides, compares their merits and demerits, and highlights sustainable approaches to enhance the utilization of microbial pesticides, phytopesticides, and nanobiopesticides for improved agriculture and health.

Summary: Root-associated microbial communities play a crucial role in the health and development of plants. By secreting root exudates, plants influence the soil microbiome, which in turn affects plant-soil interactions. Understanding the interaction between plant roots and the soil microbiome could lead to increased crop production and reduced reliance on synthetic fertilizers.
