Virulence and genetic diversity among isolates of Mycosphaerella fijiensis in two regions of Brazil.
Black sigatoka, caused by the fungus Mycosphaerella fijiensis (anamorphic stage: Paracercospora fijiensis), was first detected in Brazil in early 1998 in the Benjamin Constant and Tabatinga municipalities in the State of Amazonas, near to where the borders of Brazil, Colombia, and Peru converge. Understanding how cultivars react to the pathogen, and characterizing the genetic variability of iso...
متن کاملBioinformatics Prediction of Polyketide Synthase Gene Clusters from Mycosphaerella fijiensis
Mycosphaerella fijiensis, causal agent of black Sigatoka disease of banana, is a Dothideomycete fungus closely related to fungi that produce polyketides important for plant pathogenicity. We utilized the M. fijiensis genome sequence to predict PKS genes and their gene clusters and make bioinformatics predictions about the types of compounds produced by these clusters. Eight PKS gene clusters we...
متن کاملIN VITRO EVALUATION OF ANTIMICROBIAL PEPTIDES AGAINST Mycosphaerella fijiensis MORELET AND THEIR INTERACTION WITH SOME CHEMICAL FUNGICIDES EVALUACIÓN IN VITRO DE PÉPTIDOS ANTIMICROBIANOS CONTRA Mycosphaerella fijiensis MORELET Y SU INTERACCIÓN CON ALGUNOS FUNGICIDAS QUÍMICOS
The interest in the use of antimicrobial peptides to control fungal diseases in banana plants has been rising in the last years. In this paper we analyzed the antifungal activity of different peptides on the in vitro development of Mycosphaerella fijiensis and found that they inhibited fungal mycelial growth and ascospore germination. All peptides evaluated displayed activity against the fungus...
متن کاملSensitivity to Protectant Fungicides and Pathogenic Fitness of Clonal Lineages of Phytophthora infestans in the United States.
ABSTRACT Since 1991, dramatic changes have occurred in the genetic composition of populations of Phytophthora infestans in the United States. Clonal lineages recently introduced into the United States (US-7 and US-8) are more common now than the previously dominant lineage (US-1). To help determine why these changes occurred, four clonal lineages of P. in-festans common during the early 1990s i...
متن کاملIsolation of retro-transcribed RNA from in vitro Mycosphaerella fijiensis-infected banana leaves.
High polyphenol and polysaccharide levels in plant tissues such as banana fruit and leaves constitute a significant challenge to the extraction of sufficient amounts of high-quality RNA required for cDNA library synthesis and molecular analysis. To determine their comparative effectiveness at eliminating polyphenols, polysaccharides and proteins, three protocols for RNA extraction from in vitro...
