Genetic and Biological Diversity of Trichoderma stromaticum, a Mycoparasite of the Cacao Witches'-Broom Pathogen.
ABSTRACT The witches'-broom disease, caused by the basidiomycete Crinipellis perniciosa, is the most limiting factor for cacao cultivation in Brazil. Trichoderma stromaticum is a mycoparasite of the witches'-broom pathogen of cacao that is currently being applied in the field to manage the disease in Bahia State, Brazil. In this work, molecular and traditional methods were used to study the gen...
متن کاملTranscriptomic Analysis of Paulownia Infected by Paulownia Witches'-Broom Phytoplasma
Phytoplasmas are plant pathogenic bacteria that have no cell wall and are responsible for major crop losses throughout the world. Phytoplasma-infected plants show a variety of symptoms and the mechanisms they use to physiologically alter the host plants are of considerable interest, but poorly understood. In this study we undertook a detailed analysis of Paulownia infected by Paulownia witches'...
متن کاملIdentification and characterization of conserved and variable regions of lime witches' broom phytoplasma genome.
Several segments (∼20 kbp) of the lime witches' broom (LWB) phytoplasma genome (16SrII group) were sequenced and analysed. A 5.7 kbp segment (LWB-C) included conserved genes whose phylogenetic tree was consistent with that generated using 16S rRNA genes. Another 6.4 kbp LWB phytoplasma genome segment (LWB-NC) was structurally similar to the putative mobile unit or sequence variable mosaic ge...
متن کاملGenotypic characterization of enterotoxigenic Escherichia coli strains causing traveler's diarrhea.
This study aims to characterize the presence of virulence factors of enterotoxigenic Escherichia coli (ETEC) causing traveler's diarrhea. Among 52 ETEC isolates, the most common toxin type was STh, and the most frequent colonization factors (CFs) were CS21, CS6, and CS3. On the other hand, the nonclassical virulence factors EAST1 and EatA were frequently present.
متن کاملGenetic analysis of ‘Candidatus Phytoplasma aurantifolia’ associated with witches’ broom on acid lime trees
"Candidatus Phytoplasma aurantifolia" is associated with witches' broom disease of lime in Oman and the UAE. A previous study showed that an infection by phytoplasma may not necessarily result in the physical appearance of witches' broom symptoms in some locations in Oman and the UAE. This study investigated whether phytoplasma strains belonging to "Ca. P. aurantifolia" (based on the 16S rRNA g...
