Summary: Island biogeography has traditionally focused on abiotic factors, but recent research has highlighted the importance of biotic interactions in shaping island flora. One important association occurs between plants and nitrogen-fixing bacteria, and it has been found that these bacteria limit plant establishment on islands. This has implications for global plant biogeography and ecosystem development.

Summary: This research focused on the performance of 10 common bean genotypes under water deficit stress and their symbiotic relationship with 10 Rhizobium strains. Some genotypes, such as PHA-0432 and PHA-0683, showed tolerance to drought, while others like PHA-0471 had better yield under both irrigated and water stress conditions. Additionally, it was observed that an increase in dry nodular weight in Rhizobium inoculation tests resulted in lower seed yield in beans.

Summary: This study aims to isolate and characterize symbiotic mutants in common bean (Phaseolus vulgaris) in order to understand the symbiotic nitrogen fixation (SNF) process in this important food crop. Three non-nodulating mutants were identified and their impairments in different symbiotic steps were characterized. The responsible mutated gene is being mapped for further understanding of SNF in common bean.

Summary: The dual inoculation of AMF and Rhizobia significantly increased seedling survival, plant height, stem diameter, plant vigor, nodule numbers, active nodulation rate and dry matter yield of forage legumes. However, the nodule dry weight and dry matter content were reduced. Therefore, the dual inoculation could be a suitable alternative to reduce reliance on chemical fertilizers in semi-arid regions.

Summary: Plants can be colonized by fungi with both harmful and beneficial effects. One way the fungi colonize is by secreting effector proteins that change the plant's physiology to suit the fungus. Arbuscular mycorrhizal fungi (AMF), the oldest plant symbionts, may benefit from using effectors. Recent research has focused on understanding the function, evolution, and diversification of AMF effectors through genome analysis and transcriptomic studies. However, only a small fraction of the predicted effector proteins have been characterized, limiting our understanding of how they manipulate their host plants and which plant proteins they interact with.

Summary: The study investigated the impact of two fungicides on the performance of arbuscular mycorrhizal fungi (AMF) and found that low doses of the fungicides enhanced root colonization by AMF, while high doses suppressed their performance. The fungicides generated biphasic response curves in irradiated soil, indicating a hormetic effect on AMF.

Summary: The study found that perennial legumes may have synergistic effects with AMF and rhizobia, while annual plants do not. AMF and rhizobia can increase phosphorus and nitrogen tissue concentrations in plants to varying degrees. Microbial responses to co-infection are closely related to synergisms in plant growth.

Summary: Microplastics have diverse effects on soil and plant growth, altering soil structure and microbial activity, which in turn affects the abundance and activity of arbuscular mycorrhizal fungi. The impacts of microplastics may also change how plants respond to other global change factors, highlighting the need for further research on their overall impact on ecosystems.

Summary: The study investigated the role of nutrients in arbuscular mycorrhizal fungal improvement of biological nitrogen fixation (BNF) by Bradyrhizobium sp. and increases in Pratylenchus thornei population density in mung bean. The results showed that the combination of AMF and P improved BNF, whereas AMF alone improved BNF and nodulation. Inoculation with AMF increased the shoot concentrations of P and Zn. Rhizobia increased seed yield greater than the addition of N. Pratylenchus thornei populations increased with AMF, but decreased with the addition of N, P, and Zn.

Summary: The study evaluated the effect of dietary inulin on the intestinal bacterial communities of Penaeus vannamei through 16S metagenomic analysis. The results showed differences in the composition of bacterial communities between the inulin treatment and control groups, but no significant differences in microbial diversity. Most bacterial organisms in all samples exhibited genes related to carbohydrate and amino acid metabolism, while fewer genes related to energy, lipid, and cofactors and vitamin metabolism were observed.

Summary: Endolysins have been proposed as potential antibacterial alternatives for aquaculture, especially against Vibrio species. In this study, the biochemical characterization of LysVpKK5 endolysin encoded by the VpKK5 phage infecting Vibrio parahaemolyticus was conducted. The enzyme displayed unexpected activity patterns under different conditions, such as inhibition by Zn2+ and optimal muralytic activity at pH 10.

Summary: This research focuses on the epigenetic changes in tomato plants primed for pathogen resistance, showing that treatment with beta-aminobutyric acid (BABA) results in a significant reduction in global cytosine methylation, particularly in CHH sequence contexts. The differentially methylated regions (DMRs) identified mainly consist of hypomethylated CHH DMRs, which are enriched in gene promoters and DNA transposons. Genes overlapping with CHH DMRs are enriched for stress response-related gene ontology terms and promoters of genes differentially expressed in response to infection with Botrytis cinerea. However, the majority of primed genes do not contain DMRs and the overall distribution of methylated cytosines in primed genes is not affected by BABA treatment. Therefore, it is suggested that methylation may confer priming via in-trans regulation and/or by targeting a smaller group of regulatory genes controlling stress responses.

Summary: This study investigated the molecular mechanisms underlying the interaction between Phytophthora capsici and Capsicum chinense, a susceptible cultivar. Three elicitors were used to induce early defense in the plants, and the expression of defense-related genes was analyzed. The results showed that MeJA and BABA elicitors reduced disease symptoms and up-regulated genes related to the JA/ET signaling pathway. This suggests that JA signaling plays an important role in the early defense against P. capsici.

Summary: White shrimp farming is a significant aquaculture activity globally, but the intensification process can have negative impacts on shrimp health, leading to dysbiosis. This study examines the bacterial load and microbial population changes in the hepatopancreas of Penaeus vannamei infected with pathogenic Vibrio parahaemolyticus strain associated with acute hepatopancreatic necrosis disease (AHPND). The results reveal a significant shift in the microbial community structure, with an increase in Vibrio genus dominance before the visible manifestation of the disease.
