Other claims from this paper (9)
- Intervention effect Pb significantly decreased soil pH, organic matter and nitrogen availability in the Cuminum cyminum field experiment.
- Intervention effect Pb significantly decreased available phosphorus and potassium in the soil of Cuminum cyminum.
- Intervention effect Pb altered soil enzyme activities by suppressing urease and acid phosphatase activity in the Cuminum cyminum field experiment.
- Intervention effect Pb enhanced soil catalase activity in the Cuminum cyminum field experiment.
- Intervention effect Pb stress increased rhizosphere microbial richness at low and moderate Pb levels in Cuminum cyminum.
- Intervention effect Pb stress selectively enriched metal-tolerant Sphingomonas, Arenimonas and Gemmatimonas in the rhizosphere of Cuminum cyminum.
- Observation Functional analyses showed a broad enhancement of rhizosphere microbial metabolic potential in Cuminum cyminum samples, particularly in amino acid, carbohydrate and energy metabolism.
- Association Pb exposure was associated with accumulation of amino acids, organic acids and flavonoids in Cuminum cyminum roots.
- Association Soil physicochemical properties correlated more strongly with plant growth than root metabolites or rhizosphere microorganisms under Pb stress.
