Abstract
Four potato clones with host gene-mediated resistance to potato leafro ll virus (PLRV) multiplication were transformed with the PLRV coat pro tein (CP) gene. Plants of lines expressing high levels of transcript w ere highly resistant to PLRV multiplication; virus concentration was o nly 20-40 ng/g of leaf, which is approximately 1% of the concentration reached in susceptible cultivars. The effects of the transgenic and h ost-derived resistance genes appear to be additive.
