Abstract

Crown gall disease of tobacco was found in Iwate Prefecture, Japan in 1995. Ten bacterial isolates, obtained from the galls of tobacco, were identified as Agrobacterium tumefaciens (Smith and Townsend 1907) Conn 1942 biovar 1 based on their ability to induce galls on the 14 tested plants, including tobacco after needle-prick inoculation, and on 12 cultural, physiological, and biological characteristics. The growth of the causal organism was not inhibited in vitro by agrocin of A. radiobacter strain K84. This report is the first on the natural occurrence of crown gall caused by A. tumefaciens on tobacco plants.
