a Sequence alignment of Argonaute 1 (Ago1) from whitefly B. tabaci MEAM1 and other species including Drosophila melanogaster, Tribolium castaneum, Bombyx mori, Rattus norvegicus and Homo sapiens. b Structure of the partial Argonaute proteins predicted using the NCBI Conserved Domains Server. Conserved PAZ and Piwi-like domains were identified in the assembled B. tabaci Ago1
