Here, we generated Nicotiana benthamiana transgenic lines containing Oryza sativa miR528 as backbone, expressing amiRNAs targeting RNA-dependent RNA polymerase (RdRp) gene of Cymbidium mosaic virus (CymMV) and Odontoglossum ringspot virus (ORSV). The amiRNA transgenic lines could express amiR-CymMV and confer high percentage resistance to CymMV, while lack of detectable level of amiR-ORSV expression in amiR-ORSV transgenic N. benthamiana plants led to weak resistance to ORSV infection. In this project, we provide the first report of CymMV-resistant transgenic N. benthamiana plants based on amiRNA strategy. We believe that this amiRNA approach can be extended to generate CymMV-resistant transgenic orchids. © 2018 The Author(s).||Source Title:||Scientific Reports||URI:||http://scholarbank.nus.edu.sg/handle/10635/152523||ISSN:||20452322||DOI:||10.1038/s41598-018-28388-9|
