Some Leucaena-nodulating strains of Rhizobium can degrade mimosine (Mid+) and are less inhibited by mimosine in the growth medium than the mimosine-nondegrading (Mid-) strains. Ten Mid+ strains were identified that did not degrade 3-hydroxy-4-pyridone (HP), a toxic intermediate of mimosine degradation. However, mimosine was completely degraded by these strains and HP was not accumulated in the cells when these strains were grown in a medium containing mimosine as the sole source of carbon and nitrogen. The mimosine-degrading ability of rhizobia is not essential for nodulation of Leucaena species, but it provides growth advantages to Rhizobium strains that can utilize mimosine, and it suppresses the growth of other strains that are sensitive to this toxin.
