Previously, we reported induction of RNA interference effects in B. cockerelli via in vitro-prepared dsRNA/siRNAs after intrathoracic injection, and after feeding of artificial diets containing these effector RNAs. In order to deliver RNAi effectors via plant hosts and to rapidly identify effective target sequences in plant-feeding B. cockerelli, here we developed a plant virus vector-based in planta system for evaluating candidate sequences. We show that recombinant Tobacco mosaic virus (TMV) containing B. cockerelli sequences can efficiently infect and generate small interfering RNAs in tomato (Solanum lycopersicum), tomatillo (Physalis philadelphica) and tobacco (Nicotiana tabacum) plants, and more importantly delivery of interfering sequences via TMV induces RNAi effects, as measured by actin and V-ATPase mRNA reductions, in B. cockerelli feeding on these plants. RNAi effects were primarily detected in the B. cockerelli guts. In contrast to our results with TMV, recombinant Potato virus X (PVX) and Tobacco rattle virus (TRV) did not give robust infections in all plants and did not induce detectable RNAi effects in B. cockerelli. The greatest RNA interference effects were observed when B. cockerelli nymphs were allowed to feed on leaf discs collected from inoculated or lower expanded leaves from corresponding TMV-infected plants. Tomatillo plants infected with recombinant TMV containing B. cockerelli actin or V-ATPase sequences also showed phenotypic effects resulting in decreased B. cockerelli progeny production as compared to plants infected by recombinant TMV containing GFP. These results showed that RNAi effects can be achieved in plants against the phloem feeder, B. cockerelli, and the TMV-plant system will provide a faster and more convenient method for screening of suitable RNAi target sequences in planta.", "link"=>"http://www.mendeley.com/research/rna-interference-towards-potato-psyllid-bactericera-cockerelli-induced-plants-infected-recombinant-t", "reader_count"=>39, "reader_count_by_academic_status"=>{"Unspecified"=>2, "Student > Doctoral Student"=>6, "Researcher"=>14, "Student > Ph.

Previously, we reported induction of RNA interference effects in <i>B. cockerelli</i> via <i>in vitro</i>-prepared dsRNA/siRNAs after intrathoracic injection, and after feeding of artificial diets containing these effector RNAs. In order to deliver RNAi effectors via plant hosts and to rapidly identify effective target sequences in plant-feeding <i>B. cockerelli</i>, here we developed a plant virus vector-based <i>in planta</i> system for evaluating candidate sequences. We show that recombinant <i>Tobacco mosaic virus</i> (TMV) containing <i>B. cockerelli</i> sequences can efficiently infect and generate small interfering RNAs in tomato (<i>Solanum lycopersicum</i>), tomatillo (<i>Physalis philadelphica</i>) and tobacco (<i>Nicotiana tabacum</i>) plants, and more importantly delivery of interfering sequences via TMV induces RNAi effects, as measured by actin and V-ATPase mRNA reductions, in <i>B. cockerelli</i> feeding on these plants. RNAi effects were primarily detected in the <i>B. cockerelli</i> guts. In contrast to our results with TMV, recombinant <i>Potato virus X</i> (PVX) and <i>Tobacco rattle virus</i> (TRV) did not give robust infections in all plants and did not induce detectable RNAi effects in <i>B. cockerelli</i>. The greatest RNA interference effects were observed when <i>B. cockerelli</i> nymphs were allowed to feed on leaf discs collected from inoculated or lower expanded leaves from corresponding TMV-infected plants. Tomatillo plants infected with recombinant TMV containing <i>B. cockerelli actin</i> or <i>V-ATPase</i> sequences also showed phenotypic effects resulting in decreased <i>B. cockerelli</i> progeny production as compared to plants infected by recombinant TMV containing <i>GFP</i>. These results showed that RNAi effects can be achieved in plants against the phloem feeder, <i>B. cockerelli</i>, and the TMV-plant system will provide a faster and more convenient method for screening of suitable RNAi target sequences <i>in planta</i>.</p></div>", "links"=>[], "tags"=>["Agricultural biotechnology", "Pest control", "Biochemistry", "Nucleic acids", "rna", "RNA interference", "biotechnology", "microbiology", "Virology", "Molecular cell biology", "gene expression", "Plant science", "Plant pathology", "Plant pests", "interference", "induced", "plants", "infected", "recombinant", "mosaic"], "article_id"=>724558, "categories"=>["Medicine", "Biological Sciences"], "users"=>["Hada Wuriyanghan", "Bryce W.
