Abstract :

Some Rhizobial species carry symbiotic plasmids which contain rhizopine genes (mosA, mosB and mosC). Rhizopine (3-O-methyl scyllo-inosamine) producing Rhizobial strains enhance legume roots nodulation. Nodule formation in legume roots enhances nitrogen fixation and consequently feed or fodder yield. Treatment of lucerne roots with rhizopine and inoculating with rhizopine producing Sinorhizobium meliloti strain (L5-30) and non-producing Rhizobial strain (Rm1021) showed variation in the time of appearance and number of nodules produced on the roots. Nodules were first observed six days after inoculation of rhizopine treated and non-treated lucerne roots with either Rhizobial strain L5-30 or Rm1021. Significantly, more nodules were later (between 14 and 30 days) produced in lucerne roots treated with rhizopine than those not treated with rhizopine.
