Resumo: | Aims: Our goal was to understand the symbiotic behaviour of a Mesorhizobium strain expressing an exogenous 1-aminocyclopropane-1-carboxylate (ACC) deaminase, which was used as an inoculant of chickpea (Cicer arietinum) plants growing in soil. Methods and Results: Mesorhizobium ciceri LMS-1 (pRKACC) was tested for its plant growth promotion abilities on two chickpea cultivars (ELMO and CHK3226) growing in nonsterilized soil that displayed biotic and abiotic constraints to plant growth. When compared to its wild-type form, the M. ciceri LMS-1 (pRKACC) strain showed an increased nodulation performance of c. 125 and 180% and increased nodule weight of c. 45 and 147% in chickpea cultivars ELMO and CHK3226, respectively. Mesorhizobium ciceri LMS-1 (pRKACC) was also able to augment the total biomass of both chickpea plant cultivars by c. 45% and to reduce chickpea root rot disease susceptibility. Conclusions: The results obtained indicate that the production of ACC deaminase under free living conditions by Mesorhizobium strains increases the nodulation, plant growth abilities and biocontrol potential of these strains. Significance and Impact of the Study: This is the first study regarding the use of a transformed rhizobial strain expressing an exogenous ACC deaminase in different plant cultivars growing in soil. Hence, obtaining Mesorhizobium strains with high ACC deaminase activity is a matter of extreme importance for the development of inoculants for field applications. |
