Caracterização de estirpes de Ralstonia solanacearum isoladas de plantas de batata com murcha bacteriana, por PCR-Rep e RAPD

Abstract: Considerado como um dos mais sérios patógenos da batata (Solanum tuberosum), em regiões de clima tropical, subtropical, assim como em zonas mais quentes de clima temperado, Ralstonia solanacearum é uma espécie com significativa diversidade genética. Ela é caracterizada em um sistema binário de raças e biovares, com base nas espécies hospedeiras e na capacidade de utilizar diferentes fontes de carbono. A tentativa de utilizar a resistência genética como forma de controle de R. solanacearum não tem demonstrado e… Show more

“…It is interesting to highlight that, in this review, some studies about the genetic variability of this bacterial population in Brazil report that the existence of diversity among strains oftentimes is correlated with its geographical origin (SILVEIRA et al, 2005;FONSECA et al, 2014), similarly to what was established for the classification into phylotypes. Therefore, the lower local bacterial variability allows disease control through the use of resistant cultivars recommended for each region of the country, although care should be taken against the dissemination of strains via propagation material.…”

“…Subsequently, its occurrence was reported in potato in South of Brazil, although in lower frequency than R3Bv2 (LOPES; NAZARENO;FURIATTI, 1993;MACIEL et al, 2001;MORAES, 2002;SILVEIRA et al, 2005). Moreover, under special conditions of moisture and temperature, it has caused significant losses in commercial eucalypt nurseries in the States of Espírito Santo, Santa Catarina, Maranhão, Minas Gerais, Bahia, Pará, and Goiás (ALFENAS et al, 2006;AUER;.…”

“…Diversos autores (Bringel et al, 2004;Silveira et al, 2005;Costa et al, 2007) têm direcionado seus estudos para a caracterização e diversidade de isolados de R. solanacearum em estados brasileiros. Entretanto, todos esses estudos focam a raça 1 do patógeno, não sendo registrado, até o momento, um estudo de caracterização da diversidade de isolados de R. solanacearum raça 2 coletados em regiões brasileiras.…”
