Variabilidade genética de Xanthomonas axonopodis pv. passiflorae

Abstract: A mancha bacteriana, causada por Xanthomonas axonopodis pv. passiflorae, é uma das mais importantes doenças do maracujazeiro, podendo limitar a produção dessa frutífera em algumas regiões do País. O uso de resistência genética e controle químico, juntamente com o emprego de medidas de exclusão, são as práticas de controle da doença mais recomendadas. Para o desenvolvimento de variedades resistentes é necessário conhecer tanto a variabilidade genética do hospedeiro quanto do patógeno. Nesse trabalho foi estudad… Show more

“…Pathogen's virulence and, consequently, the expression of disease symptoms may be influenced by environmental conditions (GARCÍA-GUZMÁN et al, 2016), plant variables, such as genetic variability, age at inoculation, growth condition, nutritional status (FUHRMANN et al, 2014;WANGUNGU et al, 2014), and pathogen characteristics, such as genetic variability, isolate aggressiveness, and inoculum concentration (NAKATANI et al, 2009;CAMERA et al, 2012). Some of these variables could possibly explain divergences between our results and those reported in the literature.…”

“…Considerable genetic variability in the resistance of yellow passion fruit to CABMV has also been described by Oliveira et al (2013) and Cerqueira-Silva et al (2015). Moreover, analysis of genetic diversity among Xap and CABMV isolates reported existence of variability for aggressiveness within and among Xap populations (Nakatani et al 2009), as well as genetic variability among CABMV isolates (Melo et al 2015). This information supports the possibility of existing pathogen-host interactions, which could lead to different responses from genotypes to pathogen isolates (Lopes et al 2006, Fuhrmann et al 2014.…”

“…In a study using random amplified polymorphic markers to assess the genetic diversity of 50 pathogenic isolates of X. axonopodis pv. passiflorae sampled from four similar eco-geographical regions, no correlation was found between location and grouping (Nakatani et al, 2009). Similarly, although we collected P. ananatis samples from three different eco-geographical regions, there was no evident relationship between the collection sites and group composition (Figure 3).…”
