Abstract TheRhizobium leguminosarum biovartrifolii symbiotic plasmid pRtr5a has been transferred toR. leguminosarum biovarphaseoli RCR 3644-S1. The transconjugant selection had been done byTrifolium pratense plants. All transconjugants lacked the resident pSym, but had complete pRtr5a, and were Fix+ onT. repens andT. alexandrinum, Fix− onT. subterraneum, and formed a few small white and Fix− nodules onPhaseolus vulgaris. It is shown that this nodulation onP. vulgaris is due to pRtr5a. The presence of pRtr5a and/or the passage throughTrifolium pratense nodules provoke(s) the recipient strain symbiotic plasmid loss.
