| Abstract: | Barley stripe mosaic virus (BSMV) was the first reported and still widely used virus-induced gene silencing (VIGS) vector for monocotyledons including wheat and barley. Despite BSMV’s reported infectivity on maize (Zea mays), the use of the virus as a vector in maize has not been optimized. Here, we assayed infectivity of BSMV in different maize cultivars by vascular puncture inoculation. Through knockdown of the endogenous host phytoene desaturase gene, we demonstrate for the first time that BSMV can be used as a VIGS vector in maize. This adds BSMV to the repertoire of tools available for functional studies in maize. |
