1. Metabolomic and Histological Response of Passiflora cincinnata Infected with Cowpea aphid-borne mosaic virus (CABMV) Reveals Changes in Asymptomatic and Symptomatic Phases
Passion fruit woodiness disease, caused by the Cowpea aphid-borne mosaic virus (CABMV), is one of the leading phytosanitary challenges of passion fruit production. Passiflora cincinnata has been recognized for its potential in genetic improvement due to its highest resistance to CABMV and other phytopathogens. Metabolomic and histological alterations of P. c

2. Microbiolization of cowpea seeds with commercial strains of Trichoderma asperellum and T. harzianum
ABSTRACT Seed microbiolization has been increasingly contributed to researches due to its beneficial action in the initial growth of seedlings and control of phytopathogens. Thus, the aim of this study was to evaluate the initial growth and control of fungi associated with cowpea seeds by the seed microbiolization with commercial strains of Trichoderma spp.

3. Síntese de nanopartículas de prata (AgNPs) por Fusarium concolor e a inibição de fitopatógenos
RESUMO The use of nanoparticles (NPs) in agriculture represents an important technological innovation, which can be employed in the production of nanofertilizers, nanocides or pesticides encapsulated in nanoparticles for controlled release. Silver NPs are recognized for their applications in agriculture, biotechnology and medicine. The objective of this pape

4. Compostos voláteis de fungos conidiais sapróbios da Amazônia Meridional no controle in vitro de fitopatógenos
RESUMO Estudos sobre compostos orgânicos voláteis (COVs) produzidos por fungos conidiais sapróbios da Amazônia (FCSA) ainda são inexistentes. Assim, verificou-se a produção de COVs de FCSA e, seu potencial no controle de fitopatógenos in vitro. Utilizou-se os FCSA Beltrania rhombica, Brachysporiella sp., Dictyochaeta sp., Gonytrichum sp. e avaliou-se

5. Kasugamycin on Leifsonia xyli subsp. xyli in the in vitro culture of sugarcane
RESUMO: Um dos maiores entraves para o crescimento da produção de cana-de-açúcar é a infecção por fitopatógenos, principalmente pela bactéria Leifsonia xyli subsp. xyli (Lxx), agente causal do raquitismo-da-soqueira, doença que mais causa perdas a cultura. Assim, este trabalho teve como objetivo, avaliar os efeitos do antimicrobiano casugamicina s

6. Chemical constituents of essential oil from Murraya paniculata leaves and its application to in vitro biological control of the fungus Sclerotinia sclerotiorum
ABSTRACT Besides their value as therapeutic resources, medicinal plants may also be used as sources of active ingredients against phytopathogens. Fungi can grow and cause spoilage in food, thus, resusting in decrease in its quality and quantity. This research aimed at evaluating the effect of essential oil from Murraya paniculata (ML-EO) leaves on mycelial

7. Benefits Associated with the Interaction of Endophytic Bacteria and Plants
ABSTRACT The endophytic bacteria belong to a larger group of microorganisms that have their life-cycle partly or entirely inside the plant and are located in intra and inter-cellular spaces or in the vascular tissue. These bacteria can be found colonizing aerial parts or roots. This review aims to analyze the colonization strategies of endophytic bacteria th

8. Athelia (Sclerotium) rolfsii in Allium sativum: potential biocontrol agents and their effects on plant metabolites
Abstract Garlic (Allium sativum L.) plays an important role in popular culture due to its dietary and medicinal uses. It is also used to produce a wide range of pharmacologically interesting molecules. Several pathogens affect garlic plants, especially Athelia (Sclerotium) rolfsii, a fungus that is widespread and causes large economic losses. It causes direc

9. Uso combinado de radiación UV-C y biorecubrimiento de quitosán con aceites esenciales para el control de hongos en papaya Maradol
Abstract Anthracnose and soft rot cause deterioration of quality as well as large losses during post-harvest handling of papaya fruits. The single strategies for disease control is little efficient. We analyzed the effect of to integrate control strategies on the incidence of disease caused by the inoculation of spores of the fungi Colletotrichum gloeospori

10. Antifungal activity of metabolites of the endophytic fungus Trichoderma brevicompactum from garlic
The endophytic fungus strain 0248, isolated from garlic, was identified as Trichoderma brevicompactum based on morphological characteristics and the nucleotide sequences of ITS1-5.8SITS2 and tef1. The bioactive compound T2 was isolated from the culture extracts of this fungus by bioactivity-guided fractionation and identified as 4β-acetoxy-12,13-epoxy-Δ9-t

11. Establishment of an inducing medium for type III effector secretion in Xanthomonas campestris pv. campestris
It is well known that the type III secretion system (T3SS) and type III (T3) effectors are essential for the pathogenicity of most bacterial phytopathogens and that the expression of T3SS and T3 effectors is suppressed in rich media but induced in minimal media and plants. To facilitate in-depth studies on T3SS and T3 effectors, it is crucial to establish a

12. Caracterização taxonômica de espécies do gênero Xanthomonas / Taxonomic characterization of Xanthomonas species
Xanthomonas species are responsible for diseases causing economic losses in many crops. These phytopathogens have been subject of several taxonomic studies resulting in significant changes at interespecific or infraspecific level. This study aimed the taxonomic characterization of Xanthomonas species including: (1) differentiation and phylogenetic analysis o
