Description
Summary:Seventy-five pectinolytic strains collected from vegetables grown in the counties of Santarém, Belterra, and Mojuí dos Campos, located in the western region of the Pará State, Brazil, were studied according to their pathological and genetic variability. The strains were grouped in 5 clusters according to pathogenicity in potato, pepper, carrot, and onion, and 38 strains were selected for genetic analysis using rep-PCR. These strains were divided into 35 genetic groups according to rep-PCR at 70% similarity. These results indicated high pathological and genetic variability of the strains causing soft rot in vegetables in the western region of the Pará State, which will be used in etiological research and for the development and assessment of management techniques for the soft rot in vegetables in this region. RESUMO: Setenta e cinco isolados de bactérias pectinolíticas coletados de hortaliças cultivadas nos municípios de Santarém, Belterra e Mojuí dos Campos, região oeste do Estado do Pará, Brasil, foram estudadas de acordo com sua variabilidade patológica e genética. Os isolados foram agrupados em cinco grupos de acordo com a patogenicidade em batata, pimenta, cenoura e cebola, e 38 isolados foram selecionados para análise genética por rep-PCR. Esses isolados foram divididos em 35 grupos genéticos de acordo com rep-PCR a 70% de similaridade. Esses resultados indicaram alta variabilidade patológica e genética dos isolados causadores da podridão mole em hortaliças da região oeste do Pará, os quais serão utilizados em pesquisas etiológicas e para o desenvolvimento e avaliação de técnicas de manejo da podridão mole em hortaliças nesta região.
