Virus-induced gene editing free from tissue culture.

Virus-induced gene editing (VIGE) has reached an inflection point. Although conceived as an alternative to traditional methods of producing gene-edited plants, VIGE has historically relied on the very technologies it was meant to supersede-specifically, tissue-culture-mediated transgenesis. Recent VIGE innovations, however, have finally proved its viability as an independent method for plant gene editing. Here we discuss the advances in plant genome engineering VIGE may unlock, what progress has been made towards achieving these advances and the challenges that continue to impede that progress.
