Resumo: | One of the main factors limiting agricultural production is the attack of insects, pathogens and weeds, which can cause significant losses in the culture. Euschistus heros (Heteroptera: Pentatomidae) is one of the most important stink bug species found in soybean, with occurrence distributed throughout the Brazilian production area. In an attempt to reduce the damage caused by this and other insects, producers depend almost exclusively on the use of insecticides. However, the indiscriminate use of these products has been causing serious management problems, such as the selection of resistant populations leading to the inefficiency of products available on the market. Therefore, the development of alternative control tools, such as gene silencing based on RNA interference (RNAi) and CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is necessary. RNAi is a highly conserved mechanism in eukaryotic organisms and by which the messenger RNA molecule (mRNA) is cleaved by the gene-silencing machinery, leading to inactivation of gene expression (Knockdown). CRISPR, on the other hand, is a gene editing tool with which it is possible to carry out modification at the DNA level, introducing or eliminating specific DNA sequences from the genome (knockout). During the last years, the use of RNAi and CRISPR has attracted the interest of researchers, mainly in the study of the functions of genes during insect’s development and reproduction, which will allow the future development of alternative control strategies. Thus, considering the importance of RNAi and the CRISPR / Cas9 system in the study of functional genomics and in the development of new tools for the management of insect pests, the objectives of this study include: i) to identify the main components of the RNAi machinery present in E. heros, as well as validating the functionality of this tool in E. heros; ii) a review showing the potential use of the RNAi tool in a non-transformative approach; iii) the use of parental RNAi as a tool in the study of gene functions in E. heros; iv) the combination of RNAi and CRISPR/Cas9 as functional genomic tools in the Neotropical bug, E. heros. This information provides novel and important dataset on RNAi machinery and its efficiency, the future perspective of non-transformative RNAi approaches and the use of RNAi and CRISPR as tools in functional genetic studies, underpinning future strategies to improve RNAi and CRISPR in E. heros and other piercing-sucking insects species important in agriculture. |

Dissertation (PhD) – PostGraduation Program in Crop Protection (UFPel) and in Bioscience Engineering (UGent)http://guaiaca.ufpel.edu.br/handle/prefix/8383One of the main factors limiting agricultural production is the attack of insects, pathogens and weeds, which can cause significant losses in the culture.

Euschistus heros (Heteroptera: Pentatomidae) é uma das espécies de maior importância encontradas na cultura da soja, com ocorrência distribuída em toda área produtora brasileira. Na tentativa de reduzir os danos causados por esse e outros insetos, produtores dependem quase que exclusivamente do uso de inseticidas. Entretanto, o uso indiscriminado desses produtos vem causando sérios problemas de manejo, como a seleção de populações resistentes levando a ineficiência dos produtos disponíveis no mercado. Diante disso, é necessário o desenvolvimento de ferramentas alternativas de controle, tais como silenciamento gênico baseado em RNA de interferência (RNAi) e CRISPR (Repetições Palindrômicas Curtas Agrupadas e Regularmente Interespaçadas). O RNAi é um mecanismo altamente conservado em organismos eucariotos e pelo qual a molécula de RNA mensageiro (RNAm) é clivada pela maquinaria de silenciamento, levando a inativação da expressão gênica (Knockdown). Já o CRISPR é uma ferramenta de edição gênica com a qual é possível realizar modificação a nível de DNA, introduzindo ou eliminando sequências específicas do DNA (knockout). Nos últimos anos, a utilização do RNAi e CRISPR tem atraído o interesse de pesquisadores no estudo das funções dos genes no desenvolvimento e reprodução dos insetos, o que permitirá o desenvolvimento de estratégias alternativas de controle. Assim, considerando a importância do RNAi e do sistema CRISPR/Cas9 no estudo da genômica funcional e no desenvolvimento de novas ferramentas para o manejo de insetos-praga, os objetivos deste estudo incluem: i) identificar os principais componentes da maquinaria de RNAi presentes em E. heros, assim como validar a funcionalidade dessa ferramenta em E. heros; ii) uma revisão mostrando o uso potencial da ferramenta RNAi em uma abordagem nãotransformativa; iii) o uso do RNAi parental como ferramenta no estudo das funções gênicas em E. heros; iv) a combinação de RNAi e CRISPR/Cas9 como ferramentas genômicas funcionais no percevejo Neotropical, E. heros. Essas informações fornecem novos e importantes conjuntos de dados sobre a maquinaria de RNAi e sua eficiência, a perspectiva futura da utilização do RNAi via não-transformativa e do uso de RNAi e CRISPR como ferramentas em estudos genéticos funcionais, apoiando estratégias futuras para melhorar RNAi e CRISPR em E. heros e outras espécies de insetos perfuradores e sugadores importantes na agricultura.Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPqengUniversidade Federal de PelotasPrograma de Pós-Graduação em FitossanidadeUFPelBrasilFaculdade de Agronomia Eliseu MacielCNPQ::CIENCIAS AGRARIAS::AGRONOMIA::FITOSSANIDADEGene silencingGene knockdownGene knockoutPest managementFunctional genomicsSilenciamento gênicoManejo de insetos-pragaGenética funcionalTranscriptome analysis and exploring RNAi and CRISPR in the Neotropical stink bug, Euschistus herosAnálise do transcriptoma e exploração do RNAi e CRISPR no percevejo neotropical, Euschistus herosinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesishttp://lattes.cnpq.br/4419738369350420http://lattes.cnpq.br/5332476815885964Smagghe, Guyhttp://lattes.cnpq.br/5628387257846847Garcia, Flávio Roberto Mellohttp://lattes.cnpq.br/0371096131093979Zotti, Moises JoãoCagliari, Deiseinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFPel - Guaiacainstname:Universidade Federal de Pelotas (UFPEL)instacron:UFPELTEXTCagliari.pdf.txtCagliari.pdf.txtExtracted texttext/plain497740http://guaiaca.ufpel.edu.br/xmlui/bitstream/prefix/8383/6/Cagliari.pdf.txt68890e345bb99a077606f9e6be372e60MD56open accessTHUMBNAILCagliari.pdf.jpgCagliari.pdf.jpgGenerated Thumbnailimage/jpeg1290http://guaiaca.ufpel.edu.br/xmlui/bitstream/prefix/8383/7/Cagliari.pdf.jpg01ad6a2c6e1ce7d6edc37fbb1bc4bac5MD57open accessCC-LICENSElicense_urllicense_urltext/plain; charset=utf-849http://guaiaca.ufpel.edu.br/xmlui/bitstream/prefix/8383/2/license_url924993ce0b3ba389f79f32a1b2735415MD52open accesslicense_textlicense_texttext/html; charset=utf-80http://guaiaca.ufpel.edu.br/xmlui/bitstream/prefix/8383/3/license_textd41d8cd98f00b204e9800998ecf8427eMD53open accesslicense_rdflicense_rdfapplication/rdf+xml; charset=utf-80http://guaiaca.ufpel.edu.br/xmlui/bitstream/prefix/8383/4/license_rdfd41d8cd98f00b204e9800998ecf8427eMD54open accessLICENSElicense.txtlicense.txttext/plain; charset=utf-867http://guaiaca.ufpel.edu.br/xmlui/bitstream/prefix/8383/5/license.txtfbd6c74465857056e3ca572d7586661bMD55open accessORIGINALCagliari.pdfCagliari.pdfapplication/pdf6499779http://guaiaca.ufpel.edu.br/xmlui/bitstream/prefix/8383/1/Cagliari.pdf062a077a59e2ed6abdb4edf615da0604MD51open accessprefix/83832023-07-13 04:13:18.34open accessoai:guaiaca.ufpel.edu.br:prefix/8383VG9kb3Mgb3MgaXRlbnMgZGVzc2EgY29tdW5pZGFkZSBzZWd1ZW0gYSBsaWNlbsOnYSBDcmVhdGl2ZSBDb21tb25zLg==Repositório InstitucionalPUBhttp://repositorio.ufpel.edu.br/oai/requestrippel@ufpel.edu.br || repositorio@ufpel.edu.br || aline.batista@ufpel.edu.bropendoar:2023-07-13T07:13:18Repositório Institucional da UFPel - Guaiaca - Universidade Federal de Pelotas (UFPEL)false |
