摘要
By means of infectivity assays, tobacco ringspot virus (TRSV) but not tobacco mosaic virus (TMV) was detected in the terminal 0.5 mm of the root tips from infected bean plants, suggesting that TRSV but not TMV can infect root meristems. Presence of TRSV in the root meristems was confirmed by electron microscopic detection of characteristic particles in dividing cells of the root tips and in cells of the inner root cap. © 1969.
