Agrobacterium VirE2 proteins can form a complex with T strands in the plant cytoplasm

S B Gelvin. J Bacteriol. 1998 Aug.

Abstract

Wild-type VirE2 and VirD2 proteins from Agrobacterium tumefaciens contain nuclear targeting sequences (NLS) that are likely involved in directing transferred T strands to the plant nucleus. An A. tumefaciens virE2 virD2DeltaNLS double mutant was able to form tumors on VirE2-producing transgenic tobacco but not on wild-type tobacco. Because this mutant bacterial strain contains no known T-strand nuclear targeting signal, the data indicate that wild-type VirE2 proteins produced by the plant can interact with the T strands in the plant cytoplasm and direct them to the nucleus.
