[Cloning transport protein genes for two strains of tobacco mosaic virus and their expression in Escherichia coli cells].

Recombinant constructs expressing fusion (His)6 movement proteins of two strains (Cruciferous and Vulgare) of tobacco mosaic virus were generated by cloning the PCR-amplified fragments into the pQE-9 vector. The movement proteins containing N-terminal (His)6 affinity tags were purified on a metal chelate adsorbent.
