Variabilidade genética em isolados de Curtobacterium flaccumfaciens

Abstract: A cultura do feijoeiro está sujeita à incidência de várias doenças que acarretam perdas significativas na produção, dentre as quais encontra-se a murcha-de-curtobacterium ou murcha bacteriana, causada por Curtobacterium flaccumfaciens pv. flaccumfaciens (Cff). Atualmente a murcha-de-curtobacterium tem se constituído em um novo problema para a cultura do feijoeiro em várias regiões brasileiras. A resistência genética tem sido o meio mais eficiente no controle da doença, porém a possibilidade da existência de va… Show more

“…The number of variable sites (3.5 to 12.6%) is comparable to what was found in Clavibacter michiganensis (5.0 to 12.8%) (Jacques et al, 2012). Our findings are in agreement with other studies on genetic diversity and phylogenetic relationships in C. flaccumfaciens using rep-PCR (Souza et al 2006), and MLSA (Osdaghi et al 2018b).…”

“…The genetic variability of C. f. pv. flaccumfaciens has been previously studied by pulsed-field gel electrophoresis (PFGE), amplified fragment length polymorphism (AFLP) (Agarkova et al 2012;Guimarães et al 2003), rep-PCR (Souza et al, 2006;Agarkova et al, 2012) and BOX-PCR (Guimarães et al 2003). However, these methods suffer from significant drawbacks such as the incorrect identification of PCR patterns based on subjective gel interpretation, and difficulty to reproduce the results in other laboratories (Tancos et al 2015).…”

“…As variações na sensibilidade ao silicato de alumínio entre isolados, verificada neste estudo, sugerem a ocorrência de variabilidade genética na população de Cff, confirmando com as observações de Souza et al (24). Assim, ressalta a importância do conhecimento da variabilidade genética entre populações para futuros estudos que objetivem recomendar uso de produtos.…”

“…According to Valentini et al (2011), the resistance inheritance of this pathogen is polygenic and, according to Souza et al (2006b), Wendland et al (2008), and Torres et al (2009b), the occurrence of genetic diversity and widespread dissemination in the producing regions of Brazil, makes the development of resistance sources even more difficult. For this reason, techniques have been developed to identify this bacterium in common bean crops (Maringoni 2002, Hsieh et al 2005, Herbes et al 2008, as well as to evaluate the resistance of genotypes and lines, with a view to the development of new resistant cultivars (Maringoni 2002, Souza et al 2006a, Theodoro et al 2007).…”
