Summary: The objective of this study was to assess the impact of biofertilizers containing plant growth-promoting rhizobacteria (PGPR) and arbuscular mycorrhizal fungi (AMF) on the tolerance of quinoa to both non-saline and saline conditions. The two microbial symbiotes were applied individually and/or in combination in a greenhouse experiment. Various morphological and physiological parameters were measured under normal and stress conditions. The results showed that the combination of PGPR and AMF significantly improved the growth and physiological responses of quinoa under high salinity, indicating that these biofertilizers can enhance quinoa's tolerance to salt stress.

Summary: Spodoptera frugiperda larvae reared with Bacillus amyloliquefaciens GB03 inoculated sweet basil leaves showed negative effects on the insect development, leading to lower larval and pupal weights, and an extended period for larval-adult development. Adult emergence was reduced, but consumption rate remained unaffected, indicating no alteration in palatability. Growth rate and nutritional indicators were reduced in larvae reared from treated plants, and in choice tests, larvae avoided feeding on inoculated leaves.

Summary: In recent years, various approaches have been developed to mitigate the adverse effects of salinity stress on plants, but some of them are not environmentally friendly. Plant growth-promoting rhizobacteria (PGPR) have been found to enhance the productivity of saline soil without harming the environment by reducing oxidative damage, maintaining ionic homeostasis, enhancing antioxidant machinery, and regulating gene expressions. PGPR also regulates photosynthetic attributes and enhances salinity tolerance in plants. Additionally, PGPR plays a significant role in the synthesis of phytohormones and secondary metabolites in plants under salt stress.

Summary: This study evaluates the potential effectiveness of two bacterial species, Azospirillum brasilense and Paenibacillus dendritiformis, in enhancing growth and yield of melon and tomato plants under salinity stress. The results show that these bacteria can efficiently colonize plant roots and significantly improve the growth and yield of melon plants under saline conditions. However, their effects on tomato plants are minimal. Additionally, bacterial inoculation reduces stress levels in salt-stressed melon plants.

Summary: The study identified two endophytes with inhibitory effects on downy mildew in Papaver somniferum, one of which enhanced the plant's resistance to the disease by activating the salicylic acid-dependent defense pathway. The enhanced resistance was achieved by differential expression of transcripts related to signal transduction, protein modification, disease/defense proteins, transcription factors, and phytohormones in the endophyte-treated plants. Enhanced salicylic acid content was observed in the endophyte-treated plants after exposure to the pathogen, shedding light on the molecular mechanisms underlying the resistance.

Summary: In extreme desert environments, black septate endophytes (DSE) can benefit the relict plant Gymnocarpos przewalskii by assisting it to survive and maintain ecosystem stability. The colonization of DSE in the roots of G. przewalskii varies significantly with seasons and sites, with soil properties being a major factor affecting the composition of DSE. Additionally, the functional metabolite composition of DSE strains varies greatly with different drought levels and isolates, indicating the potential complementarity between different strains in helping hosts cope with drought stress.
