In this study, we collected soybean inter-root soil (clay soil) from the cold region of Heilongjiang Province, China, screening for cold-tolerant phosphorus- and potassium-solubilizing bacteria by gradient-cooling-directed design mixed bacterial agents. This study screened phosphorus-solubilizing constructed We analyzed strain’s phosphorus/potassium solubilizing capacity, as well its organic acid secretion ability, to reveal mechanism detoxification phosphorus potassium.

This article presents a systematic review of the ecophysiological mechanisms underpinning essential role plant-growth-promoting microorganisms (PGPMs) in improving rice yield and quality. The scientific literature is thoroughly reviewed, highlighting how PGPMs positively influence growth, development, health plants. Key aspects, such as nitrogen fixation, nutrient solubilization, hormone production, disease resistance induction, are emphasized. Additionally, technological advancements related to PGPM use analyzed, including identification effective strains, formulation enhanced biofertilizers, genetic engineering. concludes that represent promising tool with which boost sustainability productivity cultivation, providing robust foundation for future research practical applications field crucial global food security.

Microbial symbioses deal with the symbiotic interactions between a given microorganism and another host. The most widely known investigated microbial symbiosis is association leguminous plants nitrogen-fixing rhizobia. It one of best-studied plant–microbe that occur in soil rhizosphere oldest extensively studied for past several decades globally. Until recently, it used to be common understanding among scientists field rhizobia ecology root nodules thousands species only contain With advancement molecular microbiology coming into being state-of-the-art biotechnology innovations, including next-generation sequencing, has now been revealed living legumes are not alone. Microbiome studies such as metagenomics nodule community showed that, addition rhizobia, other bacteria referred non-rhizobial endophytes (NREs) exist nodules. This review provides an insight occurrence legume beneficial roles tripartite legumes, (NREs).
