Resumo: A soja é considerada uma das culturas mais importantes no Brasil, em função de seu alto valor sócio-econômico, determinado pelas inúmeras aplicações de seus produtos e subprodutos e consequente expressão no mercado interno e externo. No entanto, a cultura desta oleaginosa é frequentemente ameaçada com a ocorrência de um vasto número de doenças, que podem acarretar depreciação do produto, redução no rendimento e perdas econômicas para os produtores. Dentre as principais doenças bacterianas que afetam a cultura da soja, destacam-se a pústula bacteriana, causada por Xanthomonas axonopodis pv. glycines (Xag); o crestamento bacteriano, causado por Pseudomonas savastanoi pv. glycines (Psg); e a murcha de Curtobacterium causada por Curtobacterium flaccumfaciens pv. flaccumfaciens (Cff), ocasionando perdas na produção de até 40%. A condição sanitária das sementes é extremamente importante se considerarmos que elas são veículos desses agentes fitopatogênicos que nelas podem se alojar e serem levados ao campo, provocando redução na germinação e vigor, e originando focos primários de infecção de doenças. O presente trabalho teve por objetivo desenvolver nova metodologia de diagnóstico com o uso das técnicas moleculares que permitissem detectar e identificar a presença de Psg, Xag e Cff em sementes de soja por meio do desenvolvimento de primers espécie específicos. Os primers desenhados a partir de sequências da região espaçadora 16S-23S RNAr, mostraram-se altamente específicos e sensíveis. O par de primers Curto2f/p322anti gerou um fragmento de 675 pb e capacidade de detecção a partir de 0,01 ng de DNA genômico e aproximadamente 5x103 UFC/PCR; o par de primers Psgl/p322anti gerou um fragmento de 500 pb e o grau mínimo de sensibilidade foi de 1 pg de DNA genômico e cerca de 80 UFC/PCR; o par de primers Xanth2f/p322anti gerou um fragmento de 545 pb e capacidade de detecção a partir de 1 ng de DNA genômico e cerca de 700 UFC/PCR. Posteriormente, as sementes de soja foram infectadas artificialmente nas condições de 1; 0,5 e 0,1% de infecção. Nas amplificações com os primers espécie-específicos desenvolvidos, foi possível detectar as fitobactérias em todos os níveis de infecção testados diretamente do extrato bruto, e nas amplificações após o enriquecimento do extrato (BIO-PCR) o sinal positivo foi potencializado
Abstract: Soybean is considered one of the most important crops in Brazil, due to its high socio-economic value, determined by its several products and sub products and its significant expression on the internal and external market. However, this oleaginous plant is often affected by the occurrence of different diseases, which cause depreciation of the product, reduction in yield and substantial economic losses. Among the main bacterial diseases, the bacterial pustule, caused by Xanthomonas axonopodis pv. glycines (Xag), the bacterial blight caused by Pseudomonas savastanoi pv. glycines (Psg), and bacterial tan spot caused by Curtobacterium flaccumfaciens pv. flaccumfaciens (Cff), producing yield losses of up to 40%. The seed health is extremely important since they are considered vehicles of pathogenic agents which can be led to the field, causing germination reduction and vigor; and yielding primary infection of the diseases. This study aimed to develop a new method of diagnosis using molecular tools to detect and identify Psg, Xag or Cff in soybean seeds, through species-specific primers. The primers were designed from sequences of the 16S-23S rRNA and they were highly specific and sensitive. The pair of primers Curto2f/p322anti generated a fragment of 675 bp and was able of detecting down to 0.01 ng of genomic DNA and about 5x103 CFU/PCR; the primer set Psgl/p322anti produced a fragment of 500 bp and reached a detection limit of 1 pg of genomic DNA and about 80 CFU/PCR; and Xanth2f/p322anti yielded a fragment of 545 bp and could detect up to 1 ng of genomic DNA and about 700 CFU/PCR. Subsequently, soybean seeds were artificially infected in the following conditions: 1, 0,5% and 0,1% infection. In the amplifications using the species-specific primers, it was possible to detect the three different phytobacteria at all tested levels of infection directly of the crude extract and in the amplifications after enrichment of the extract (BIO-PCR), the positive signal was enhanced

Texte intégralA tuberculose da oliveira, causada pela bactéria Pseudomonas savastanoi pv. savastanoi (Pss), é uma importante doença do olival ainda sem tratamento conhecido. Esta doença afeta a parte aérea das oliveiras e caracteriza-se por um crescimento anormal dos tecidos, principalmente no tronco e ramos. Neste trabalho foi caracterizada a comunidade bacteriana que habita a filosfera da oliveira, de modo a elucidar o seu possível papel na defesa da planta contra a tuberculose da oliveira. Uma abordagem dependente de cultivo foi usada para descrever as populações da superfície (epífitos) e do interior (endófitos) de folhas, caules e nódulos de duas cultivares com diferentes suscetibilidades a esta doença. Para alguns dos isolados obtidos foi testada a sua capacidade antagonista contra Pss em ensaios in vitro, tendo os mecanismos associados a este antagonismo sido também avaliados. A eficácia do isolado mais promissor, Bacillus amyloliquefaciens P41, na redução do desenvolvimento da doença e na melhoria do fitness da planta foi avaliada através de ensaios in planta. No geral, a comunidade bacteriana da filosfera da oliveira inclui membros pertencentes principalmente a Proteobacteria, em particular a Gammaproteobacteria. A composição bacteriana foi principalmente afetada pela cultivar do hospedeiro e em menor grau pelo órgão, que teve um maior impacto nos epífitos. Adicionalmente, cada cultivar/órgão foi aparentemente seletiva através de OTUs bacterianos específicos. A tuberculose da oliveira revelou ter também um impacto na estrutura da comunidade bacteriana, mas com diferentes efeitos, dependentes da cultivar e do habitat na planta hospedeira. Na verdade, o seu efeito foi mais notório na cultivar mais suscetível à doença e nos endófitos. Um total de 27 isolados inibiram significativamente o crescimento de Pss, tendo os isolados com uma maior capacidade antagonista sido isolados da cultivar suscetível. Esta capacidade antagonista deveu-se provavelmente à produção de compostos voláteis, enzimas líticas e sideróforos. B. amyloliquefaciens P41 reduziu a severidade da doença em até 43.7% e a população de Pss em até 26.8%, e simultaneamente melhorou o fitness da planta hospedeira, podendo ser possivelmente considerado um candidato promissor no controlo da tuberculose da oliveira. Estudos adicionais são necessários para identificar o papel funcional destas bactérias e dos mecanismos envolvidos na proteção da planta hospedeira contra a tuberculose da oliveira.
Olive knot (OK), caused by Pseudomonas savastanoi pv. savastanoi (Pss), is an important olive orchard disease with still no treatment known. This disease affects the aerial part of the olive trees and is characterized by overgrowth formations (knots) mainly on trunk and branches. In this work was characterized the bacterial community inhabiting the olive tree phyllosphere, in order to elucidate its possible role on plant defense against OK disease. A culture-dependent approach was used to describe the bacterial populations in (epiphytes) and on (endophytes) leaves, twigs and knots of two cultivars with different susceptibility to OK disease. Some of the isolates obtained were screened for their antagonistic effect against Pss in in vitro assays, and their mechanisms were also evaluated. The efficacy of the most promising isolate, Bacillus amyloliquefaciens P41, in reducing OK development and improving plant fitness was evaluated through in planta assays. Overall, the bacterial community of olive tree phyllosphere comprised members belonging mainly to Proteobacteria, in particular Gammaproteobacteria. Bacterial composition was primarily impact by host cultivar, and, to a lesser extent, by plant organ which had a more control over epiphytes. In addition, each cultivar/organ apparently was selective towards specific bacterial OTUs. OK disease showed also to have an impact on the structure of bacterial communities, but with variable effects depending on the host cultivar and plant habitat. Indeed, its effect was most notorious in OK-susceptible cultivar and within endophytes. A total of 27 isolates inhibited significantly Pss growth, being the ones with the greatest antagonistic activity from the tissues surface of OK-susceptible cultivar. Such ability was potentially due to the production of volatile compounds, lytic enzymes and siderophores. B. amyloliquefacients P41 reduced OK disease’s severity up to 43.7% and Pss population size up to 26.8% and simultaneously increased plant fitness, suggesting to be a promising candidate for controlling OK disease. More research are still required to identify the functional role of these bacteria and the mechanisms involved in conferring host plant protection to OK disease.
