Variabilidade genética de Colletotrichum guaranicola usando marcadores AFLP

Abstract

ResumoFoi detectada a variabilidade genética de vinte isolados de Colletotrichum guaranicola (albuq.) provenientes de diferentes localidades produtoras de guaraná no amazonas, utilizando-se marcadores moleculares aFLP. Foi possível separar os isolados em dois grupos. o coeficiente de variação genética entre os isolados foi de 0,0216 e a similaridade genética foi de 94,95%, confirmando que os isolados pertencem à mesma espécie, no entanto, foi observada variabilidade intra-específica. PalavRas-Chave: antracnose, guaranazeiro, marcador molecular Variability of Colletotrichum guaranicola using AFLP markers abstRaCtThe genetic variability of twenty Colletotrichum guaranicola (albuq.) isolates from different fields of guarana in amazonas, was studied using molecular aFLP markers. The isolates were separated into two groups. The genetic variability coefficient was 0.0216 and the genetic similarity was 94.5%, confirming that the isolates belongs to the same species, however, an intraspecific variability was observed.

“…Ducke]. It is estimated that at least 70% of the national market is intended for the manufacture of soft drinks, while the remainder is marketed in the forms of syrup, stick, powder, extract and other products (Bentes and Costa Neto 2011 ). Furthermore, the derivatives from guarana are economically valuable resources throughout the pharmaceutical and cosmetics industries (Kuri 2008 ) and are widespread in the global market.…”
