Summary: Plants use secondary metabolites to defend themselves against herbivore insects. This study investigates the effect of the natural compound methyl salicylate (MeSA) on the interaction between Brassica rapa subsp. chinensis and peach potato aphids (Myzus persicae) and their natural enemy (Diaeretiella rapae). The results show that MeSA treatment significantly reduces aphid performance.

Summary: Paenibacillus polymyxa is a versatile bacterium with potential applications in promoting plant growth, providing biocontrol, and protecting against abiotic stresses. Its association with plants and diverse interactions make it an interesting research topic for studying host-microbe communications and the influence of the environment on these interactions.

Summary: In arid and semi-arid regions, high temperature stress affects plant growth and development, as well as agricultural output. This study identified thermotolerant rhizobacterial strains that promote plant growth under high temperature stress. Inoculation with these strains significantly improved mustard growth, root architecture, and physiological attributes. This suggests that thermotolerant rhizobacteria with plant growth-promoting activity can mitigate high temperature stress in crops.

Summary: Root-knot nematodes are significant pests for agriculture worldwide, and biological control is a potential alternative for their management. This study evaluated the effectiveness of a dual-strain bacteria combination (FMCH001 and FMCH002) in reducing nematode infection in tomato plants. The results showed that the combination had nematicidal properties, inhibiting nematode egg-hatching, larval survival, and attractiveness to the roots. It also interfered with giant cell development, leading to a reduction in nematode reproduction.

Summary: Plant growth-promoting rhizobacteria in the genus Bacillus have been shown to reduce populations of some aphids, but have no effect on others. However, plants treated with Bacillus spp. have higher rates of aphid parasitism, suggesting that these bacteria can shape above-ground interactions by altering field infestations of pests and indirectly affecting natural enemy responses.

Summary: The study showed that enrichment of protective microbiota in the rhizosphere facilitates disease suppression, while disruption of protective rhizobacteria can increase the incidence of disease. Artificial disruption of Gram-positive bacteria in rhizosphere soil resulted in higher occurrence of bacterial wilt in tomatoes. Identification of specific Gram-positive bacteria species in healthy rhizosphere soil contributed to plant immunity activation and enhanced plant disease resistance.

Summary: This study reveals that bacteria emit volatile compounds that can have complex effects on plant growth, with different concentrations of plant growth-inhibiting volatiles (PGIVs) and plant growth-promoting volatiles (PGPVs) having varying impacts at different distances. High concentrations of PGIVs can suppress plant growth and promote immunity, while low concentrations of PGPVs can enhance plant growth.

Summary: In this study, we sequenced the genome of Ralstonia pseudosolanacearum strain SL1931, isolated from pepper stems. This strain belongs to the phylotype I of R. solanacearum, the causal pathogen of bacterial wilt. We found that strain SL1931 has a distinct type III effector profile compared to the reference genome strain GMI1000.

Summary: Microbes in the digestive tracts of insects, such as Enterococcus spp. and Enterobacter spp., play a crucial role in the host's behavior and development. This study found that eradication of Enterococcus spp. in the gut of G. mellonella larvae accelerated the transition from larvae to pupae. The research also revealed the upregulation of immune response genes in pupae and the upregulation of hormone genes in larvae.
