| zygocactus virus x-based expression vectors and formation of rod-shaped virus-like particles in plants by the expressed coat proteins of beet necrotic yellow vein virus and soil-borne cereal mosaic virus. | expression vectors were constructed from 35s promoter-containing full-length cdna clones of zygocactus virus x (zvx). the expression of foreign genes was driven by the zvx coat protein (cp) subgenomic promoter. it was successful only when the variable region downstream of the conserved putative promoter region gsttaagtt(x(12-13))gaa was retained. most of the zvx cp gene, except for a short 3' part, was replaced by the corresponding sequence of the related schlumbergera virus x (svx) and its cp s ... | 2006 | 16432032 |
