摘要：

The rôle of the bacteriocin, agrocin 84, in the biological control. of crown gall was investigated by constructing new bacteriocinogenic strains. A small plasmid which codes for the ability to produce agrocin 84 has been identified and transferred to recipient strains by conjugation. Two donor strains were used; the avirulent strain 84 and the virulent strain 398. Agrocin production and virulence in the latter strain have been separated by genetic manipulation and avirulent, agrocin producing derivatives have been produced. Avirulent transconjugants which produced agrocin 84 varied in their effectiveness as biological control gents. Evidence is presented that this was probably due to variation in rate of growth of the different strains in the inoculation sites. © 1979.
