Empowering plant evo‐devo: Virus induced gene silencing validates new and emerging model systems

Abstract

It is increasingly recognized that current established model systems are not sufficient to understand the evolution of biodiversity. The main limitation in developing additional model systems is the difficulty or inability to perform functional studies of target genes. Evolutionary developmental (evo-devo) biologists have adopted a transient transgenic technique, developed over the last decade for agricultural applications, which is allowing functional studies in the most disparate plant lineages. From monocots to dicots and from herbs to trees, virus-induced gene silencing (VIGS) has opened up a world of opportunities in plant evo-devo.
