Abstract

The genome of an attenuated isolate L_<11>A-Fukushima (L_<11>A-F) of Tomato mosaic virus was cloned, its complete nucleotide sequence was determined, and full-length clone of L_<11>A-F was then assembled. Its transcripts systemically infeeted tomato without causing any symptom development. When a missense back mutation at the nucleotide correspondent to nucleotide 2350 of the genome was introduced into the clone, its transcripts produced distinct mosaic on the upper leaves of the inoculated tomato, and virus accumulation in the upper leaves increased about five times. The missense mutation in the L_<11>A-F genome was thus confirmed to be sufficient to attenuate its virulence on tomato. (Received June 10, 2002 ; Accepted October 30, 2002)
