Mesorhizobium loti, formerly known as Rhizobium loti,[1] is a
Gram negative species of bacteria found in the
root nodules of many plant species.[2] Its name is a reference to Lotus corniculatus, a flowering plant from which it was originally isolated.
Genetics
The complete genome sequence of a strain of M. loti was determined in 2000.[3]
Unusually, M. loti has two
Ku genes (mlr9624 and mlr9623) instead of the usual one in each bacterial species. (Ku is involved in
NHEJ repair.)[4]
