Novel approaches on identification of conserved miRNAs for broad-spectrum Potyvirus control measures

In this study, we predicted evolutionarily conserved miRNAs by BLAST searching of reported miRNAs from 15 plants against the GSS and EST sequences of banana. A total of nine miRNAs were predicted and screened in nine diverse potyvirids' hosts (Banana, Tomato, Green gram, Jasmine, Chilli, Coriander, Onion, Rose and Colocasia) belonging to eight different orders (Zingiberales, Solanales, Fabales, Lamiales, Apiales, Asperagales, Rosales and Alismatales). Results suggested that miR168 and miR162 are conserved among all the selected plants. This comprehensive study laid the foundations to design broad-spectrum antivirus resistance using miRNAs. To conclude miR168 and miR162 are conserved among many plants and play a crucial role in evading virus infection which could be used as a potential candidate for developing antiviral strategies against potyvirid infections.PMID:33743120 | DOI:10.1007/s11033-021-06271-7
