ResumoPolyamines were analyzed in 4 species of genus Agrobacterium. Not only putrescine, spermidine and spermine, but also homospermidine and thermospermine were found in A. tumefaciens, A. radiobacter, A. rubi and A. rhizogenes. Trace amounts of aminopropylhomospermidine were also observed. Norspermidine and norspermine were formed from diamonorpropane added to the medium. Aminopropylcadaverine and its aminopropyl derivative(s) (aminopentylnorspermidine and N,N′-bis(3-aminopropyl) cadaverine) were produced from the supplemented cadaverine. A strain of A. rhizogenes normally contains only putrescine and homospermidine; no other diamines, triamines and tetraamines were synthesized.
