Resumo: | Soybean seed quality is high related with crop production. Seed coat has the function of maintaining this quality, since acts as a modulator of the interactions between the internal and external environment of the seed, controls gas exchange and water to the environment and regulates germination by interfering with the mechanisms dormancy. In soybean seed husk is present lipoxygenase VLXC, which is involved in the temporary storage of nitrogen. Given the above, the objective of this study was to evaluate the expression of the gene coding for the protein VLXC on the tegument of four soybean genotypes at different times of collection after anthesis. The experiment was conducted in greenhouse Station Lowlands of Embrapa Clima Temperado and Laboratório de biotecnologia de sementes (UFPel / FAEM) in the city of Capão do Leão - RS, in a completely randomized design with three replications, and treatments arranged in a factorial model. We used four contrasting genotypes, two cultivars of yellow coat (COODETEC 202 and BMX Potência RR) and two genotypes of black coat (Tegumento Preto and IAC). Samples were collected along the integuments of developing soybean seed corresponding to periods of 25, 30, 35, 40, 45, 50 and 55 days after anthesis. Proceeded to RNA extraction of tegument, followed by obtaining the cDNA for further analysis of qRT-PCR (polymerase chain reaction of reverse transcription real-time), to quantify the relative accumulation of gene transcripts VLX-C. The level accumulation of gene transcripts VLXC cultivar CD 202 has been raised most of the times, followed by a low expression evaluated last time that corresponds with the time it was made harvesting soybeans. The strain TP and the IAC and BMX Potência RR did not show the same behavior of the cultivar CD 202, due to low accumulation of gene transcripts VLXC in all periods. The results indicate that the relative accumulation of gene transcripts VLXC in the seed coat of soybeans differs between both periods evaluated, as well as between genotypes. |

Para isso, o tegumento da semente tem como função a manutenção dessa qualidade, visto que atua como modulador das interações entre a parte interna e o meio externo da semente, controla trocas gasosas e de água com o ambiente e regula a germinação, interferindo nos mecanismos de dormência. No tegumento de sementes de soja encontra-se presente a lipoxigenase VLXC, a qual está envolvida no armazenamento temporário de nitrogênio. Diante do exposto, o objetivo deste trabalho foi avaliar a expressão do gene que codifica para a proteína VLXC no tegumento de quatro genótipos de soja, em épocas distintas de coleta após a antese. O experimento foi conduzido em casa de vegetação da Estação Terras Baixas da Embrapa Clima Temperado e no Laboratório de Biotecnologia de Sementes (UFPel/FAEM), no município de Capão do Leão - RS, em delineamento completamente casualizado, com três repetições, sendo os tratamentos arranjados em esquema bifatorial. Foram utilizados quatro genótipos de soja contrastantes quanto à coloração, duas cultivares de tegumento amarelo (COODETEC 202 e BMX Potência RR) e duas cultivares de tegumento preto (Tegumento Preto e IAC). Foram efetuadas coletas dos tegumentos ao longo do desenvolvimento da semente de soja correspondendo aos períodos de 25, 30, 35, 40, 45, 50 e 55 dias após a antese. Procedeu-se a extração de RNA dos tegumentos, seguido da obtenção do cDNA para posterior análise de qRT-PCR (Reverse transcription polymerase chain reaction in real-time) visando quantificar o acúmulo relativo de transcritos do gene VLXC. O nível de acúmulo de transcritos para o gene VLXC na cultivar CD 202 foi elevado na maioria das amostragens, seguido de baixa expressão na última época avaliada, que corresponde ao momento em que foi efetuada a colheita da soja. A linhagem TP e as cultivares IAC e BMX Potência RR não apresentaram o mesmo comportamento da cultivar CD 202, devido ao baixo acúmulo de transcritos do gene VLXC, em todas as épocas avaliadas. Os resultados obtidos indicam que o acúmulo relativo de transcritos do gene VLXC no tegumento de sementes de soja difere tanto entre as épocas avaliadas, bem como entre os genótipos estudados.application/pdfporUniversidade Federal de PelotasPrograma de Pós-Graduação em Ciência e Tecnologia de SementesUFPelBRFaculdade de Agronomia Eliseu MacielGlycine maxqPCRLipoxigenasesGlycine maxqPCRCNPQ::CIENCIAS AGRARIAS::AGRONOMIA::FITOTECNIA::PRODUCAO E BENEFICIAMENTO DE SEMENTESExpressão do gene vlxc no tegumento de sementes de sojaExpression of the vlxc gene in soybean seed coatinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFPel - Guaiacainstname:Universidade Federal de Pelotas (UFPEL)instacron:UFPELORIGINALdissertacao_carolina_terra_borges.pdfapplication/pdf918571http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/1410/1/dissertacao_carolina_terra_borges.pdf18eeef3adf6b7f2c33e02b67f0bfa596MD51open accessTEXTdissertacao_carolina_terra_borges.pdf.txtdissertacao_carolina_terra_borges.pdf.txtExtracted Texttext/plain60671http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/1410/2/dissertacao_carolina_terra_borges.pdf.txt8b34df67057f206774f50173c7783e53MD52open accessTHUMBNAILdissertacao_carolina_terra_borges.pdf.jpgdissertacao_carolina_terra_borges.pdf.jpgGenerated Thumbnailimage/jpeg1396http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/1410/3/dissertacao_carolina_terra_borges.pdf.jpgd066b4a90017df38db2967cc41c1a39aMD53open access123456789/14102016-09-27 15:14:38.101open accessoai:guaiaca.ufpel.edu.br:123456789/1410Repositório InstitucionalPUBhttp://repositorio.ufpel.edu.br/oai/requestrippel@ufpel.edu.br || repositorio@ufpel.edu.br || aline.batista@ufpel.edu.bropendoar:2016-09-27T18:14:38Repositório Institucional da UFPel - Guaiaca - Universidade Federal de Pelotas (UFPEL)false |
