Abundance, distribution and potential impact of transposable elements in the genome of Mycosphaerella fijiensis. Repositório Alice
SANTANA, M. F.; SILVA, J. C. F.; BATISTA, A. D.; RIBEIRO, L. E.; SILVA, G. F. da; ARAÚJO, E. F. de; QUEIROZ, M. V. de.
Mycosphaerella fijiensis is a ascomycete that causes Black Sigatoka in bananas. Recently, the M. fijiensis genome was sequenced. Repetitive sequences are ubiquitous components of fungal genomes. In most genomic analyses, repetitive sequences are associated withtransposable elements (TEs). TEs are dispersed repetitive DNA sequences found in a host genome. These elements have the ability to move from one location to another within the genome, and their insertion can cause a wide spectrum of mutations in their hosts. Some of the deleterious effects of TEs may be due to ectopic recombination among TEs of the same family. In addition, some transposons are physically linked to genes and can control their expression. To prevent possible damage caused by the...

Boto, a class II transposon in Moniliophthora perniciosa, is the first representative of the PIF/Harbinger superfamily in a phytopathogenic fungus. Repositório Alice
PEREIRA, J. F.; ALMEIDA, A. P. M. M.; COTA, J.; PAMPHILE, J. A.; SILVA, G. F. da; ARAÚJO, E. F. de; GRAMACHO, K. P.; BROMMONSCHENKEL, S. H.; PEREIRA, G. A. G.; QUEIROZ, M. V. de.
Boto, a class II transposable element, was characterized in the Moniliophthora perniciosa genome. The Boto transposase is highly similar to plant PIF-like transposases that belong to the newest class II superfamily known as PIF/Harbinger. Although Boto shares characteristics with PIF-like elements, other characteristics, such as the transposase intron position, the position and direction of the second ORF, and the footprint, indicate that Boto belongs to a novel family of the PIF/Harbinger superfamily. Southern blot analyses detected 6?12 copies of Boto in C-biotype isolates and a ubiquitous presence among the C- and S-biotypes, as well as a separation in the C-biotype isolates from Bahia State in Brazil in at least two genotypic groups, and a new...

Genetic diversity analysis of isolates of the fungal bean pathogen Pseudocercospora griseola from central and southern Brazil. Repositório Alice
ABADIO, A. K. R.; LIMA, S. S.; SANTANA, M. F.; SALOMÃO, T. M. F.; SARTORATO, A.; MIZUBUTI, E. S. G.; ARAÚJO, E. F.; QUEIROZ, M. V. de.
Planting resistant varieties is the most effective control measure against the angular leaf spot of dry beans, a fungal disease caused by Pseudocercospora griseola. However, dry bean varieties with durable resistance are not easily obtained. Knowledge about the genetic variability of the pathogen population is key for the success of dry bean breeding programs aimed at developing resistant materials, but finding suitable operationally simple and genetically accurate markers is not an easy task. The aim of this study was to assess the suitability of the ISSR-PCR technique to quantify the genetic variability of P. griseola isolates. Total DNA of 27 P. griseola isolates from Goiás, Minas Gerais, Espírito Santo, and Paraná States was extracted and amplified...
