While largely depending on other microorganisms for nitrogen (N) mineralization, arbuscular mycorrhizal fungi (AMF) can transfer N from organic sources to their host plants. Here, we compared acquisition by the AMF hyphae chitin and protein assessed effects of microbial interactions in hyphosphere. We employed vitro compartmented microcosms, each containing three distinct hyphosphere compartments amended with different (protein, chitin, or ammonium chloride), one which was enriched 15N isotope. All were supplied Paenibacillus bacteria, without protist Polysphondylium pallidum. measured effect these model microbiomes efficiency roots via hyphae. found that efficiently took up chloride, competing strongly bacteria protists. Mobilization facilitated protists, respectively. Notably, priming significantly affected abundance protists promoted mineralization Subsequently, this transferred into roots. Our results provide first unequivocal evidence acquire proteins present may play a crucial role mineralization.

ABSTRACT Ongoing climate change is negatively impacting crop productivity globally. Past research has highlighted that a diverse soil microbial community and variation in plant traits for resource acquisition can mitigate the negative impacts of factors on productivity. This study investigates effects two major environmental stressors—drought salinity stress, productivity, biomass allocation, root leaf trait responses under distinct diversities. Our results showed stress had stronger than drought stress. Shoot decreased by 30% 32.5% respectively, whereas 32% only Soil diversity did not affect Next, were mainly impacted both stresses diversity. Specific length specific area drought, tissue density was minimal Root affected communities. In contrast, nitrogen content increased, pheophytin (a breakdown product chlorophyll) when plants grown communities stresses, especially drought. These highlight importance response to stresses. We influences aboveground belowground traits, indicating need better management practices conserve promote
