A Versatile Expression Platform in Insects and Cereals Based on a Cytorhabdovirus.

In recent years, plant virus-based vectors have been widely applied to express heterologous proteins for genomic studies and commercial production. Among these versatile RNA viral vectors, the barley yellow striate mosaic virus (BYSMV)-based expression vector system has outstanding capability to express large and multiple heterologous proteins. Here we describe a detailed protocol for expression of heterologous proteins using BYSMV expression systems in monocot plants and insects.
