Genetic diversity of mycosphaerella fijiensis in brazil analyzed using an ERIC-...

The Enterobacterial repetitive intergenic consensus (ERIC) marker was used to analyze the genetic variability of Mycosphaerella fijiensis, the causative agent of Black Sigatoka disease in banana plants. A total of 123 isolates were used, which were divided into populations based on their original hosts and collection sites in Brazil. A total of 9 loci were amplified, 77.8% of which were found to be polymorphic....

Biological control of banana black Sigatoka disease with Trichoderma

Black Sigatoka disease caused by Mycosphaerella fijiensis is the most severe banana disease worldwide. The pathogen is in an invasive phase in Brazil and is already present in most States of the country. The potential of 29 isolates of Trichoderma spp. was studied for the control of black Sigatoka disease under field conditions. Four isolates were able to significantly reduce disease severity and were further t...

Virulence and genetic diversity among isolates of Mycosphaerella fijiensis in t...

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 isolates from two di...

Diversidade Microbiana da Amazônia Vol. 3

Ao divulgar o terceiro volume do livro Diversidade Microbiana da Amazônia, tendo como conteúdo, cerca de 65% dos trabalhos apresentados no 7° CDMicro – Congresso sobre Diversidade Microbiana da Amazônia - realizado no final de 2018 na cidade de Manaus, queremos agradecer aos participantes, todo o apoio dado ao nosso evento. O CDMicro vem, ao longo desses anos, contribuindo para a divulgação e troca de informaçõ...

Distribution of mating-type alleles and M13 PCR markers in the black leaf spot ...

The fungus Mycosphaerella fijiensis is the causative agent of black sigatoka, which is one of the most destructive diseases of banana plants. Infection with this pathogen results in underdeveloped fruit, with no commercial value. We analyzed the distribution of the M. fijiensis mating-type system and its genetic variability using M13 phage DNA markers. We found a 1:1 distribution of mating-type alleles, indicat...

Sigatoka-negra em bananais cultivados na região Centro-Sul do Estado do Mato Gr...

A sigatoka-negra (Mycosphaerella fijiensis Morelet) é a principal doença da bananeira e pode causar 100% de perdas na produção. O conhecimento do progresso da doença é importante para definir as estratégias de controle a serem adotadas. O objetivo deste trabalho foi estudar o comportamento da sigatoka-negra em bananeiras na região Centro-Sul do Estado do Mato Grosso. O experimento foi realizado com as cultivare...
