Biocontrole de Fusarium oxysporum f. sp. cubense por Pseudomonas spp. em banana “Prata anã”

چکیده
A bananeira apresenta diversos problemas fitossanitários, tendo destaque a murcha de Fusarium causada pelo fungo oxysporum f. sp. cubense (Foc). O uso microrganismos como o Pseudomonas, tem sido uma alternativa para biocontrole dos fitopatógenos. Com objetivo investigar capacidade controle da rizobactéria do gênero Pseudomonas em relação à atividade (Foc), foi realizado dois experimentos condições casa vegetação. delineamento inteiramente casualizados (DIC) com três tratamentos, controles e 10 repetições. Os tratamentos primeiro experimento consistiram aplicar spp. no substrato, adição Foc sem intervalo tempo. Após período inoculação substrato infestado por realizou-se plantio das mudas nos tubetes. No segundo experimento, aplicações mesmo pré-inoculação, porém inoculado primeiro, posteriormente bactéria seguida foram transferidos substrato. utilização diferentes, tempo não eficiente Foc. Observou-se que índice doença menos severo tratamento sendo melhor plantas banana cultivar Prata Anã. bactérias é economicamente viável Murcha Fusarium.

Wound-induced pectin methylesterases enhance banana (Musa spp. AAA) susceptibility to Fusarium oxysporum f. sp. cubense
Recent studies suggest that plant pectin methylesterases (PMEs) are directly involved in plant defence besides their roles in plant development. However, the molecular mechanisms of PME action on pectins are not well understood. In order to understand how PMEs modify pectins during banana (Musa spp.)-Fusarium interaction, the expression and enzyme activities of PMEs in two banana cultivars, hig...
متن کاملEndophytic bacterial diversity in banana ‘Prata Anã’ (Musa spp.) roots
The genetic diversity of endophytic bacteria in banana 'Prata Anã' roots was characterized. Two hundred and one endophytic bacteria were isolated, 151 of which were classified as Gram-positive and 50 as Gram-negative. No hypersensitivity response was observed in any of the isolates. The rep-PCR technique generated different molecular profiles for each primer set (REP, ERIC and BOX). Fifty reada...
متن کاملThe distribution and host range of the banana Fusarium wilt fungus, Fusarium oxysporum f. sp. cubense, in Asia
Fusarium oxysporum formae specialis cubense (Foc) is a soil-borne fungus that causes Fusarium wilt, which is considered to be the most destructive disease of bananas. The fungus is believed to have evolved with its host in the Indo-Malayan region, and from there it was spread to other banana-growing areas with infected planting material. The diversity and distribution of Foc in Asia was investi...

متن کاملGenome and Transcriptome Analysis of the Fungal Pathogen Fusarium oxysporum f. sp. cubense Causing Banana Vascular Wilt Disease
BACKGROUND The asexual fungus Fusarium oxysporum f. sp. cubense (Foc) causing vascular wilt disease is one of the most devastating pathogens of banana (Musa spp.). To understand the molecular underpinning of pathogenicity in Foc, the genomes and transcriptomes of two Foc isolates were sequenced. METHODOLOGY/PRINCIPAL FINDINGS Genome analysis revealed that the genome structures of race 1 and r...
