1. Symptomatology associated with “Purple top”, an emerging disease of solanaceous fruit species
ABSTRACT “Purple top” is an emerging disease that affects solanaceous crops, reported mainly on Solanum tuberosum (potato). Additionally, Bactericera cockerelli has been reported as the insect vector of Candidatus Liberibacter solanacearum (CaLso), a pathogen that has been associated with this disease. However, the information about this disease in Andea

2. Effects of waterlogging stress on plant-pathogen interaction between Fusarium poae and wheat/ barley
ABSTRACT. Waterlogging stress is one of the abiotic factors which causes damage to crops affecting yield components and grain quality of wheat and barley. On the other hand, Fusarium poae is one of the most common Fusarium species isolated from wheat and barley. The aim of this study was to evaluate the effects of waterlogging and F. poae on disease paramete

3. Growth kinetics of Escherichia coli O157:H7 on the epicarp of fresh vegetables and fruits
ABSTRACT Despite the increasing reports on the incidence of fresh vegetables and fruits as a possible vehicle for human pathogens, there is currently limited knowledge on the growth potential of Escherichia coli O157:H7 on different plant substrates. This study analyzed the selective adhesion and growth of E. coli O157:H7 on chili habanero (Capsicum chinense

4. Closely-related Xanthomonas citri subsp. citri isolates trigger distinct histological and transcriptional responses in Citrus limon
ABSTRACT Citrus canker, caused by Xanthomonas citri subsp. citri (Xcc), has an important economic impact on the citrus industry. Extensive information is available about the disease but, nevertheless, the study of plant-pathogen interactions could provide new information in the understanding of citrus canker disease. A new isolate has been identified, Xcc AT

5. PR-protein activities in table beet against Cercospora beticola after spraying chitosan or acibenzolar-S-methyl
Cercospora leaf spot (Cercospora beticola) is the most important disease of table beet in the world. In this study, the preventive application of chitosan or acibenzolar-S-methyl (ASM) to control the disease was evaluated, and the involvement of pathogenesis-related proteins in the plant-pathogen interaction was verified. Beet plants cultivar Early Wonder we

6. Estabelecimento de um patossistema modelo e análise da interação molecular planta-patógeno entre Eucalyptus grandis e Puccinia psidii Winter por meio da técnica de RNA-Seq. / Establishment of a model pathosystem and analysis of the molecular plant-pathogen interaction between Eucalyptus grandis and Puccinia psidii Winter
More than 20 million hectares are destined to Eucalyptus plantations worldwide and Brazil has the second largest planted area. The International Eucalyptus Genome Network, EUCAGEN, was created in 2007 in order to perform genomic research on Eucalyptus. Brazil provided the biological material from the model tree (Brasuz) to have the complete genome sequenced

7. Interação molecular planta-nematóide.
ABSTRACT: The endoparasitic sedentary phytonematodes of genera Heterodera, Globodera (known as cyst nematodes, CN) and Meloidogyne (the root-knot nematodes, RKN) are major crop phytopathogens, causing estimated losses of US$ 125 billion annually in the world. These plant-parasitic nematodes share some parasitism mechanisms, which ensure host-tissue invasion

8. Molecular battles between plant and pathogenic bacteria in the phyllosphere
The phyllosphere, i.e., the aerial parts of the plant, provides one of the most important niches for microbial colonization. This niche supports the survival and, often, proliferation of microbes such as fungi and bacteria with diverse lifestyles including epiphytes, saprophytes, and pathogens. Although most microbes may complete the life cycle on the leaf s

9. Ecologia de Methylobacterium spp. na planta hospedeira / Methylobacterium spp. ecology in the host plant
The genus Methylobacterium, constituted by PPFMs - pink-pigmented facultative methylotrophic, are able to fix nitrogen, nodule the host plant, produce cytokines and enzymes involved in induction of systemic resistance such as pectinase and cellulase, inducing plant growth. Methylobacterium sp. has been described as endophyte or epiphyte in different host pla

10. Potenciais hospedeiros alternativos para o fitoplasma e o espiroplasma, agentes do enfezamento do milho, e alterações bioquímicas em plantas infectadas pelo espiroplasma / Potencial hosts for maize mollicutes, agent of corn stunt, and biochemical changes in plants infected by the spiroplasma
The maize bushy stunt and corn stunt are relevant diseases caused, respectively, by a phytoplasma and a spiroplasma (Spiroplasma kunkelii). Both kinds of stunting were reported in Brazil in the beginning of the 1970´s and became economically important in the beginning of the 1980´s, with the adoption of new techniques for maize cultivation. Although this p

11. Indução de resistência em feijoeiro (Phaseolus vulgaris) por acibenzolar-S-metil contra Xanthomonas axonopodis pv. phaseoli: parâmetros bioquímicos e da produção / Induced resistance in bean plants (Phaseolus vulgaris) by acibenzolar-S-methyl against Xanthomonas axonopodis pv. phaseoli: biochemical and production parameters
The common bacterial blight disease of bean caused by the bacterium Xanthomonnas axonopodis pv. phaseoli, occurs mainly in hot and humid regions of the globe. The induced resistance consists in the increase of the plant resistance by the use of external agents, without any change in its genome. The objectives of this study were: (i) to verify the induction o

12. Interaction of Metarhizium anisopliae (Metsch), Beauveria bassiana (Bals.) and granulovirus, the main pathogens of Diatraea saccharalis (Fabr., 1794) (Lepidoptera: Crambidae) / Interação de Metarhizium anisopliae (Metsch.), Beauveria bassiana (Bals.) e vírus da granulose, principais patógenos de Diatraea saccharalis (Fabr., 1794) (Lepidoptera: Crambidae)
The sugarcane borer, Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) is naturally infected by various pathogens, the most important are Metarhizium anisopliae (Metsch) (Ascomycota: Clavicipitaceae), Beauveria bassiana (Bals.) (Ascomycota: Cordycipitaceae) and granulovirus. These microorganisms may coinfect the same host under field conditions
