NodD, the major regulatory protein of nodulation, was partially purified from Rhizobium leguminosarum 8401(pIJ1518), and its binding sequences within nodF promoter of R.l. bv. viciae were determined by DNase I footpri...
Project supported by the National Postdoctoral Science Foundation of China.
A recombinant transposon Tn5-GmSp,produced by replacing the central BglⅡfragmentwith a BamHⅠone of R1033,was utilized to detect Tn5 transposition inhibition in Rhizo-bium leguminosarum.Two types of suicide plasmids(...
