Tobacco mosaic virus (TMV) mutants Ls1 and Ni2519, temperature-sensitive (ts) in transport function in tobacco plants, were able to spread at high temperature (33 °C) in L. plants. On the other hand, TMV ts coat protein mutants retained the ts phenotype in both host plants. The ability of Ls1 and Ni2519 to spread systemically in at high temperature is probably due to the functional stabilization of the transport proteins by a factor(s) provided by the host plant. In accordance with this, Ls1 complemented the transport function of cucumber green mottle mosaic tobamovirus and red clover mottle comovirus; they acquired the ability to spread systemically at 33 °C in the plants preinfected with Ls1.
