Project description:Mesorhizobium huakuii 7653R is an α-proteobacterium that occurs either in a nitrogen-fixing symbiosis with its host plant, A. sinicus, or free-living in the soil. Investigation of whole genome gene expression level changes in Bacteroids compared to the free-living cells. Understand how M. huakuii 7653R responds to alterations in its environment and to the physiological changes that occur during bacteroid differentiation.
