General Information

General Information Comment Organism
physiological function effect of bacterial ACC deaminase overproduction on Medicago lupulina plants growth and nodulation, overview. The biomass production is significantly increased in the plants inoculated with Sinorhizobium meliloti overexpressing the Pseudomonas putida enzyme (pRKACC) or co-inoculated with wild-type Sinorhizobium meliloti and Pseudomonas putida UW4 in comparison with the plants inoculated with wild-type Sinorhizobium meliloti. The dry weight of aerial parts of plants inoculated with Sinorhizobium meliloti overexpressing the Pseudomonas putida enzyme (pRKACC) are enhanced by 31.6 % in the presence of 200 mg/kg Cu2+, and by 54.4 % in the presence of 400 mg/kg Cu2+, as compared with the plants inoculated with wild-type Sinorhizobium meliloti. The dry weight of roots is also significantly increased by 34.6 and 39.4 % in the pRKACC-strain inoculated plants treated with 200 and 400 mg/kg Cu2+. Similarly, a significant increase is also observed in the biomass production of plants co-inoculated with wild-type Sinorhizobium meliloti and Pseudomonas putida UW4 Pseudomonas putida
