Summary: In this study, endophytic bacterial isolates from roots and shoots of two distantly related rice accessions were characterized phenotypically and genotypically. Five of the most promising plant growth-promoting bacteria were selected to test their abilities to enhance growth of the four rice accessions. Plant growth enhancement was both bacterial isolate specific and plant genotype specific. The positive interactions between plant and bacteria were not easily predictable, indicating a complex relationship between plants and their microbial partners.

Summary: Seed priming methods can improve seed germination and seedling vigor, and also help plants withstand abiotic stress. Among these methods, biopriming stands out as it not only provides the aforementioned benefits but also manages biotic stress. Biopriming using beneficial microorganisms, especially plant growth-promoting bacteria, is an environmentally-friendly alternative to chemical fungicides and has been proven effective in various crops worldwide. In this study, bacterial strains were isolated from different sources and screened based on their solubilization ability of potassium, phosphorus, and production of the plant growth hormone indole acetic acid. The most efficient bacteria were identified and further examined for their additional plant growth-promoting properties. Carrot seed germination assays were conducted with the selected potent isolates, and several isolates showed positive effects on germination. The study emphasizes the role of auxins in seed germination and suggests that phosphate solubilization ability may also play a role.

Summary: This study isolated Se-tolerant plant-growth-promoting bacteria (PGPB) from soils collected from a Se tailing. The strain LWS1 belonging to Priestia sp. showed good growth in M9 medium and exhibited typical PGP characteristics. It also demonstrated tolerance to selenite (SeIV) and enhanced biomass and Se concentration in rice. These findings suggest that microbial Se biofortification through inoculating with strain LWS1 can improve Se uptake in crops.

Summary: Integrating diverse cover crops into dryland crop-fallow rotations can enhance soil nutrient and water retention, suppress soil-borne pests, and improve soil health. The effects on soil nematode communities are modulated by the functional type and mixture composition of the cover crops. Selecting cover crops with appropriate traits can improve soil health through suppression of plant-parasitic nematodes, promotion of free-living nematodes, and enhancement of soil food web complexity.

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.
