Phylogenetic and recombination analysis of Tobacco bushy top virus in China.

ABSTRACT:

Background

During the past decade, tobacco bushy top disease, which is mainly caused by a combination of Tobacco bushy top virus (TBTV) and Tobacco vein-distorting virus (TVDV), underwent a sudden appearance, extreme virulence and degeneration of the epidemic in the Yunnan province of China. In addition to integrative control of its aphid vector, it is of interest to examine diversity and evolution among different TBTV isolates.

Methods

5' and 3' RACE, combined with one step full-length RT-PCR, were used to clone the full-length genome of three new isolates of TBTV that exhibited mild pathogenicity in Chinese fields. Nucleotide and amino acid sequences for the TBTV isolates were analyzed by DNAMAN. MEGA 5.0 was used to construct phylogenetic trees. RDP4 was used to detect re
