Abstract excerpt

Mesorhizobium huakuii 7653R forms a symbiotic relationship with Astragalus sinicus to produce nitrogen-fixing root nodules under nitrogen-limiting conditions. By screening its transposon-inserted mutant library, a mutation in the lpsH gene was found to form pseudonodules on A. sinicus. Its effect was further confirmed by double-crossover mutant HK242. DNA sequence analysis revealed that the lpsH gene encodes a...
