title: Expression of the barley yellow dwarf virus-GAV movement protein and its detection in the infected and transgenic plants.
abstract: Movement proteins (MPs) that facilitate virus movement in the plants were identified in a number of plant viruses. In this study, full-length MP gene of the Chinese isolate Barley yellow dwarf virus-GAV (BYDV-GAV) was cloned and expressed in Escherichia coli. About 32% of the expressed MP was soluble providing the concentration of isopropyl-beta-D-galactopyranoside (IPTG), time of the induction, temperature and shaking speed were optimized. The soluble MP was purified using nickel-affinity column. Immune serum prepared against purified MP was used for the detection of MP in the BYDV-GAV infected leaves of oat and in the leaves of transgenic wheat plants expressing the full-length and truncated MP gene.
