Other claims from this paper (8)
- Intervention effect Under nutrient deficiency, SAAS-63 inoculation improved antioxidant activities and proline contents of lettuce compared with no inoculation.
- Intervention effect Exogenous SAAS-63 significantly increased the accumulation of macroelements and micronutrients in lettuce.
- Intervention effect SAAS-63 inoculation increased the relative abundances of Streptomyces, Actinoallomurus and Verrucomicrobia in the lettuce rhizosphere.
- Intervention effect SAAS-63 inoculation increased the relative abundance of Chloroflexi in the lettuce rhizosphere.
- Intervention effect The inoculant promoted phenylalanine use in the synthesis of lignin precursors and coumarin substances under nutrient deficiency.
- Intervention effect The inoculant inhibited the synthesis of flavone and isoflavone in lettuce under nutrient deficiency.
- Mechanism SAAS-63 may help lettuce plants recruit microbes that use trehalose, re-establishing rhizosphere carbon metabolism.
- Association Microbes were closely related to the accumulation of metabolites by correlation analysis.
