Genetic variability of Moniliophthora perniciosa isolated from Theobroma sp.

The fungus Moniliophthora perniciosa is the causal agent one of the main cacao (Theobroma cacao) and cupuassu (Theobroma grandiflorum) disease, of which have origin probably in the Amazon basin. The genetic knowledge is important for better understanding of plant pathogen evolution and control strategies. The aim of this study was to determinate genetic variability of Moniliophthora perniciosa isolates from T. grandiflorum and T. cacao trees growing in seven states of Brasil: Acre, Amapa, Amazonas, Para, Rondonia, Roraima e Bahia.
