Other claims from this paper (8)
- Observation Three categories of determinants involved in copper resistance were identified in the rhizobium by transposon mutagenesis.
- Intervention effect Mutagenesis of lipA gave the rhizobium sensitivity to copper, blocked symbiotic capacity and inhibited growth.
- Intervention effect Copper induced expression of cusB in the rhizobium.
- Intervention effect A copA deletion did not affect symbiotic capacity of the rhizobium under uncontaminated conditions.
- Intervention effect Inoculation with the lipA-defective strain decreased functional nodule numbers, total N content and plant biomass of Robinia pseudoacacia, even in uncontaminated soil.
- Intervention effect Inoculation with the lipA-defective strain decreased leghemoglobin expression level of Robinia pseudoacacia.
- Intervention effect Plants inoculated with the lipA-defective strain accumulated much less copper than plants with the wild-type or copA-defective strain.
- Mechanism A healthy symbiotic relationship between legume and rhizobia is suggested to play an important role in phytostabilization.
