Phenylphenalenones protect banana plants from infection by Mycosphaerella fijiensis and are deactivated by metabolic conversion.
Phenylphenalenones, polycyclic aromatic natural products from some monocotyledonous plants, are known as phytoalexins in banana (Musa spp.). In this study, (1) H nuclear magnetic resonance (NMR)-based metabolomics along with liquid chromatography and mass spectrometry were used to explore the chemical responses of the susceptible 'Williams' and the resistant 'Khai Thong Ruang' Musa varieties to...
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 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 کاملChemical management in fungicide sensivity of Mycosphaerella fijiensis collected from banana fields in México
The chemical management of the black leaf streak disease in banana caused by Mycosphaerella fijiensis (Morelet) requires numerous applications of fungicides per year. However this has led to fungicide resistance in the field. The present study evaluated the activities of six fungicides against the mycelial growth by determination of EC50 values of strains collected from fields with different fu...
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...
