Summary
Transgenic plants of Nicotiana benthamiana expressing single chain antibody fragments (scFv) specific for the coat protein of beet necrotic yellow vein virus (BNYVV) and non-expressing control plants were inoculated with BNYVV mechanically and by means of the vector Polymyxa betae. The scFv were presumably expressed in the endoplasmic reticulum (ER). The average time needed for infections to become detectable was longer in the scFv-expressing plants than in the non-expressing control plants. In addition, the scFv-expressing plants were partially protected against the pathogenic effects exerted by the virus on N. benthamiana plants in the late stages of infection.
