Abstract
Reverse genetics systems have only been successfully developed for a few plant rhabdoviruses. Additional systems are needed for molecular virology studies of these diverse viruses and development of viral vectors for biotechnological applications. Eggplant mottled dwarf virus (EMDV) is responsible for significant agricultural losses in various crops throughout the Mediterranean region and the Middle East. In this study, we report efficient recovery of infectious EMDV from cloned DNAs and engineering of EMDV-based vectors for the expression of foreign proteins in tobacco, eggplant, pepper, and potato plants. Furthermore, we show that the EMDV-based vectors are capable of simultaneously expressing multiple foreign proteins. The developed EMDV reverse genetics system offers a versatile tool for studying virus pathology and plant-virus interactions and for expressing foreign proteins in a range of solanaceous crops.
