Pseudorecombination between infectious cloned DNA components of tomato mottle and bean dwarf mosaic geminiviruses.

Abstract

A newly described whitefly-transmitted geminivirus infecting tomato plants in Florida induces yellow mottling symptoms on leaves, and stunted and distorted growth. The DNA-A and DNA-B components were cloned from extracts of field-infected tomato tissue; excised monomers or uncut tandem dimers of these clones were infectious when co-inoculated on to… (More)
