Development and application of sugarcane streak mosaic virus vectors

In this study, we successfully constructed Agrobacterium infiltration based infectious clone of SCSMV with different variants. Infectious clones of wild type SCSMV could efficiently infect Nicotiana benthamiana and sugarcane plants resulting in streak and mosaic symptoms on systemic leaves which were further confirmed with RT-PCR and serological assays. SCSMV variants of less adenylation displayed attenuated pathogenicity on N.benthamiana. SCSMV-based recombinant heterologous EGFP protein vector was also developed. The EGFP-tagged recombinant SCSMV could highly expressed in vegetative organs including roots. These infectious clones of SCSMV could be further developed for platform tools for both biotechnological studies and management of SCSMV disease.PMID:38394980 | DOI:10.1016/j.virol.2024.110028
