1. Characterization and variability of strains of Xanthomonas axonopodis pv. passiflorae from the state of Pará, Brazil
ABSTRACT Bacterial spot, caused by Xanthomonas axonopodis pv. passiflorae, is a disease that has limited the cultivation of passionfruit in various orchards in Brazil. The objective of this work is to characterize and evaluate the variability of 29 strains of X. axonopodis pv. passiflorae from different municipalities producing yellow passionfruit in the sta

2. Multiple resistance to bacterial halo blight and bacterial leaf spot in Coffea spp.*
RESUMO O melhoramento de plantas para resistência genética é um método importante para o manejo de doenças, pelos inúmeros benefícios e baixo custo de implementação. No presente estudo, progênies de 11 espécies de Coffea e 16 acessos selvagens de C. arabica foram testados quanto à resposta a Pseudomonas syringae pv. garcae, agente causal da manch

3. Intervalo de aplicação de óleos essenciais no controle da mancha bacteriana do tomateiro
RESUMO A mancha bacteriana do tomateiro, causada Xanthomonas spp. pode provocar perdas significativas na produção da cultura. O controle da doença é difícil e produtos alternativos devem ser avaliados. Portanto, os objetivos do trabalho foram avaliar a inibição do crescimento de Xanthomonas spp. in vitro e o intervalo de aplicação de óleos essencia

5. Evaluation of an antibacterial orthodontic adhesive incorporated with niobium-based bioglass: an in situ study
Abstract This in situ study aimed to evaluate the antibacterial and anti-demineralization effects of an experimental orthodontic adhesive containing triazine and niobium phosphate bioglass (TAT) around brackets bonded to enamel surfaces. Sixteen volunteers were selected to use intra-oral devices with six metallic brackets bonded to enamel blocks. The experim

6. Residual polysaccharides from fungi reduce the bacterial spot in tomato plants
Abstract Polysaccharides from fungal wastes were partially characterized and evaluated for their protective effects against bacterial spot caused by Xanthomonas gardneri on four tomato cultivars: Santa Cruz Kada, Natália, BRS Sena and Forty. The polysaccharides were extracted from spent mushroom substrate of Pleurotus ostreatus, residual brewery yeast (Sacc

7. First report of mixed infection by Pseudomonas syringae pathovars garcae and tabaci on coffee plantations
ABSTRACT The bacterial-halo-blight (Pseudomonas syringae pv. garcae) is disseminated by the main coffee areas in the producing states of Brazil. On the other hand, the disease bacterial-leaf-spot (Pseudomonas syringae pv. tabaci) was reported only once in coffee seedlings in a sample collected in the State of São Paulo. In mid-2015, samples of coffee leaves

8. Resistance of Xanthomonas euvesicatoria strains from Brazilian pepper to copper and zinc sulfates
ABSTRACT Bacterial spot, caused by Xanthomonas spp., is one of the major bacterial diseases in pepper (Capsicum annuum L.). The infection results in reduced crop yield, particularly during periods of high rainfall and temperature, due to the low efficiency of chemical control with copper bactericides. This study evaluated the copper and zinc sulfate sensitiv

9. Antagonistic rhizobacteria and jasmonic acid induce resistance against tomato bacterial spot
AbstractTomato bacterial spot on tomato may be caused by four species of Xanthomonas and among them X. gardneri(Xg) is the most destructive one, especially in areas irrigated using a center pivot system in Minas Gerais state and the midwest region of Brazil. Due to the ineffectiveness of chemical control and the lack of cultivars with high levels of genetic

10. UEL 175: a novel lipoxygenase-free soybean cultivar with kunitz trypsin inhibitor absence
UEL 175 is lipoxygenase-free soybean cultivar and has absence of the antinutritional factors kunitz trypsin inhibitor (SKTI). UEL 175 presents high yield potential and good adaptation under no-tillage. It is resistant to soybean stem canker, brown stem rot, frogeye leaf spot, and bacterial pustule.

11. Chemical products induce resistance to
Xanthomonas perforans in tomatoThe bacterial spot of tomato, caused by
Xanthomonas spp., is a very important disease, especially in the hot and humid periods of the year. The chemical control of the disease has not been very effective for a number of reasons. This study aimed to evaluate, under greenhouse conditions, the efficacy of leaf-spraying chemicals (acibenzolarBraz. J. Microbiol.. Publicado em: 21/07/2015
