A. Gera et al., TOBACCO MOSAIC TOBAMOVIRUS DOES NOT REQUIRE CONCOMITANT SYNTHESIS OF MOVEMENT PROTEIN DURING VASCULAR TRANSPORT, Molecular plant-microbe interactions, 8(5), 1995, pp. 784-787
A tobacco mosaic tobamovirus (TMV) mutant, which is defective in cell-
to-cell transport, moved long-distance through parts of grafted plants
that do not express TMV movement protein, MP(-), Long-distance moveme
nt of the TMV mutant in vascular tissue from MP(-) tobacco was as effi
cient as wild-type TMV, The data indicate that once in the phloem, pre
sumably the sieve elements, long-distance movement of TMV does not req
uire concomitant synthesis of MP.
