Assembly of Fe–S cluster synthesis system and electron transporters in E. coli 78-7. a Linear view of the genes. b Relative nitrogenase activity of wild-type Paenibacillus sp. WLY78, E. coli 78-7 [pBluescriptII SK (+) and pCAMBIA1301] and E. coli 78-7 strains carrying different genes. E. coli 78-7. [pBluescriptII SK (+) and pCAMBIA1301] was used as a control. Each experiment was repeated at least three times, and the error bars represent standard error
