Other claims from this paper (10)

Intervention effect Copper addition decreased nodule number and nodule dry weight of alfalfa in both symbioses compared with no added copper.
Intervention effect The symbiosis with the Cu-sensitive strain was more affected by copper than the symbiosis with the Cu-tolerant strain.
Intervention effect Under copper supply, alfalfa with the Cu-tolerant strain showed no significant change in shoot and root biomass production.
Intervention effect Under copper excess, high levels of copper were detected in different parts of alfalfa plants in both symbioses.
Intervention effect Under copper excess, the strain S412 produced a high translocation of copper to the aerial parts of alfalfa.
Observation Alfalfa plants with strain S412 accumulated large quantities of calcium in their roots and nodules.
Intervention effect Nodulation with strain S412 allowed alfalfa to maintain high levels of magnesium in all tissues.
Intervention effect Nodulation with strain S412 gave high iron levels in alfalfa nodules.
Intervention effect Under 0.5 mM copper treatment, calcium content decreased drastically in alfalfa shoots.
Recommendation The authors suggest that this symbiotic pair could be used for phytostabilization of Cu-contaminated soils.
