Summary: The study identified key effectors that modulate the symbiotic properties of Bradyrhizobium vignae strain ORS3257 in different Vigna species, highlighting the importance of these effectors for improving inoculation strategies for Vigna species cultivated in Africa and Asia. Different effectors were found to have varying impacts on different Vigna species, with some promoting nodulation while others causing incompatibility between the strain and the plant.

Summary: The distribution and functions of Type III secretion systems (T3SSs) in two important bacterial groups, nitrogen-fixing rhizobia and plant-beneficial Pseudomonas spp., are discussed. T3SSs and their effectors play important roles in legume-rhizobia symbiosis and in plant-beneficial Pseudomonas spp. The diversity of T3SSs in plant-beneficial bacteria suggests their significant roles in interkingdom interactions in the rhizosphere.

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: Nitrogen is crucial for plant survival and legumes have the ability to recruit rhizobia to fix atmospheric nitrogen. This review explores alternative nodule structures and their functions, as well as unusual aspects of nodulation, such as actinorhizal-Frankia, cycad-cyanobacteria, and non-legume Parasponia andersonii-rhizobia symbioses. Nodules are not limited to roots, but can also be found in stems and leaves. Recent research has shown that legume-rhizobia nodulation brings various benefits, including defense response priming and enhanced resistance to stress. This review discusses recent discoveries and future directions in the study of nodulation.

Summary: NopP, a T3SS effector of Mesorhizobium amorphae CCNWGS0123, is secreted through T3SS-I during early infection stages and its deficiency reduces nitrogenase activity in Robinia pseudoacacia nodules. TRAPPC13 has been identified as a target protein of NopP in R. pseudoacacia roots, showing colocalization on the plasma membrane. The interaction between NopP and TRAPPC13 affects genes associated with cell wall remodeling and plant innate immunity in early infection stages.

Summary: The search for effective methods to control plant diseases caused by bacteria is crucial for food security. Functional peptides, both natural and synthetic, have shown great potential as biopesticides due to their strong bactericidal activity, biodegradability, and low toxicity. Current research focuses on identifying peptide sequences that can be used to develop novel biopesticides.

Summary: The study expanded the catalog of T3SS effectors of Bradyrhizobium vignae ORS3257 using a multi-omics approach, showing that most of the putative effectors are regulated by TtsI and confirming the secretion of some T3Es through proteome analysis. Additionally, the research identified and validated a new potential T3Es.

Summary: Shigella, a human-restricted pathogen causing bacillary dysentery, primarily relies on a type III secretion system (T3SS) consisting of multiple components and proteins for its virulence. Studying the T3SS injectisome in Shigella and related systems helps to understand its pathogenic mechanisms and develop prevention strategies.

Summary: Rhizobia form nodules on the roots of legumes and fix atmospheric nitrogen into ammonia to support plant growth. Recent studies have found that rhizobia utilize type III effectors similar to pathogenic bacteria to induce nodule formation, providing new insights into the symbiotic mechanisms of rhizobia.

Summary: A forward genetic screening isolated an Arabidopsis mutant with a loss of plant-rhizobacteria mutualism, leading to the disclosure of a plant latent defense response (LDR) to microbial non-pathogenic factors (NPFs). The activation of LDR in the mutant, triggered by several non-pathogenic volatile organic compounds, antagonizes plant compatibility with the beneficial bacterium Bacillus amyloliquefaciens GB03, mediated through the prokaryotic pathway of chloroplastic lipid biosynthesis. This hidden layer of defense provides a mechanism for controlling compatibility with commensal or beneficial microbes parallel to the frontline immunity to microbe-associated molecular patterns (MAMPs).

Summary: Composting plants are important sources of environmental bioaerosols, but the size distribution of airborne bacteria has limited our understanding of their health risks. This study analyzed the size-related abundance and communities of airborne bacteria, especially human pathogenic bacteria, in a composting facility, providing valuable information for assessing bacterial pathogenicity and potential health impacts on workers and residents.

Summary: The study identified 18 distinct genospecies within the Rhizobium leguminosarum complex (Rlc), each separated by a distinct gap in ANI values around 96%. The 16S ribosomal RNA sequence in the Rlc is diverse but not able to distinguish between genospecies. Single genes are not reliable guides to the true phylogeny of bacterial strains within the Rlc.

Summary: The study showed that inoculation with plant growth-promoting rhizobacteria (PGPR) and grafting can enhance tomato resilience to stress induced by combined water and nutrient shortage. Different PGPR treatments had varying effects on plant biomass and fruit production under different conditions. Metabolomics analysis can be used to accelerate screening for traits related to stress tolerance.

Summary: The study evaluated the effects of different types and doses of mobile green manure (MGM) on soil nitrogen availability, plant nutrition, and yield in organic greenhouse tomatoes. The results showed that MGM treatments significantly increased mineral N content in soil and total N content in plants, leading to improved yield. However, excessive N mineralization rates may result in reduced yield during the later stages of cultivation.

Summary: This study aims to reduce the use of inorganic nitrogen fertilizer in hydroponic common bean cultivation without compromising plant performance. The 50-25% mineral-N application regime showed significant increases in nodulation, biological nitrogen fixation (BNF), and yield, while the 75-25% regime during the vegetative stage resulted in yield losses due to restricted nodulation and BNF. Both rhizobia strains stimulated nodulation and BNF, but their capacity was suppressed as the inorganic-N input increased.
