The gene encoding the triple gene block protein 1 (TGBp1) of Potato mop-top virus (PMTV) was cloned into expression vector pQE32 tagging the protein with 6xHis on the N-terminus. When the gene was enshortened on its 3¢-end by two different restriction digestions, efficient and high yield bacterial expression was achieved in both cases, as shown by sodium dodecyl sulphate polyacrylamide gel elec...

Functions of viral proteins can be regulated through phosphorylation by serine/threonine kinases in plants, but little is known about the involvement of tyrosine kinases in plant virus infection. In this study, TGBp3, one of the three movement proteins encoded by a triple gene block (TGB) of Potato mop-top virus (PMTV), was detected for the first time in PMTV-infected plants and found to be tyr...
