^aAR (acetylene reduction) normalized to values exhibited by strain CE3 (which is set to 100). 

^bAR per total nodule fresh weight, expressed as percent of the wild-type value. 

^cNumber and total fresh weight (mg) of the nodules per plant. 

^dAn isolate from nodules of CE166α. 

^eRepresentative of results with CE394 and CE395. 

^f—, small pseudonodules (not weighed).
