Resumo: | The bacterial blight (Xanthomonas axonopodis pv. manihotis) is the most important disease of cassava. To study the genetic variability of pathogen in the West of Paraná, a research was carried out at Entre Rios do Oeste, Marechal Cândido Rondon, Mercedes, Missal, Nova Santa Rosa and Pato Bragado. The isolates were characterized to amylase activity, α and β-esterase and aggressiveness. From 61 collected materials, were obtained 19 bacterial isolates, with larger incidence for varieties of human consume than those for industry. Stems from Pato Bragado, Entre Rios do Oeste and Mercedes showed incidences of 10, 27 and 10%, respectively, values smaller than those of Marechal Cândido Rondon (50%) and Nova Santa Rosa (58%). The isolates could be contained in five, six and twelve different groups to amylolytic activity, aggressiveness and esterase isoenzimes, respectively. There was not relationship between the amylase activity and aggressiveness. Marechal Cândido Rondon isolates were more aggressive than those of other sampled areas. According to the clustering for esterase, isolates from Entre Rios do Oeste, Nova Santa Rosa and Mercedes presented high similarity degree. According to the results, there is differentiation among the isolates of the bacteria presented in the studied regions. |

Para estudar a variabilidade genética desta bactéria no Oeste do Paraná, foram realizados levantamentos em Entre Rios do Oeste, Marechal Cândido Rondon, Mercedes, Missal, Nova Santa Rosa e Pato Bragado. Os isolados foram caracterizados em relação à atividade de amilase, α e β-esterase e agressividade. Dos 61 materiais vegetais coletados, obtiveram-se 19 isolados da bactéria, com maior incidência para variedades de mesa em relação àqueles para indústria. Manivas provenientes de Pato Bragado, Entre Rios do Oeste e Mercedes apresentaram incidências de 10, 27 e 10%, respectivamente, valores inferiores aos de Marechal Cândido Rondon (50%) e Nova Santa Rosa (58%). Os isolados foram agrupados em cinco, seis e 12 grupos em relação à capacidade amilolítica, agressividade e isoenzimas de esterase, respectivamente. Não houve relação entre atividade de amilase e agressividade. Isolados de Marechal Cândido Rondon foram mais agressivos que os provenientes das outras regiões. O agrupamento com base em esterase permitiu verificar que isolados provenientes de Entre Rios do Oeste, Nova Santa Rosa e Mercedes apresentaram alto grau de similaridade. Estes resultados indicam haver diferenciação entre os isolados da bactéria presentes nos municípios amostrados.Universidade Estadual de Maringá2008-03-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/96510.4025/actasciagron.v28i3.965Acta Scientiarum.
