1. Pseudomonas syringae causing bacterial canker on apple trees in Brazil
ABSTRACT In March 2016, wilt and shoot blight were observed on five-year-old apple trees (Malus domestica) cultivar Maxi Gala in a commercial orchard in São Joaquim city, state of Santa Catarina, Brazil. Isolation on culture media, biolog, biochemical, LOPAT tests, and whole genome sequencing were performed. Koch’s postulates were fulfilled on apple stems

2. Antibacterial Activity of Polygonum Orientale Extracts Against Clavibacter Michiganensis subsp. michiganensis, the Agent of Bacterial Canker of Tomato Disease
Abstract Clavibacter michiganensis subsp. michiganensis (Cmm), which is a Gram positive bacterium, causes the bacterial canker of tomato disease. The purpose of the study was to evaluate the antibacterial activity of Polygonum orientale extracts against Cmm. In this study, firstly, effects of three extracting parameters (extractive time, extractive temperat

3. INT7100 IPRO - A soybean cultivar for an extensive growing area in the South and Cerrado in Brazil
Abstract Soybean cultivars with "plasticity" traits, such as good branching ability, ensure compensation of gaps in planting. The cultivar INT7100 IPRO provides excellent branching ability and plant architecture, facilitating control of pests and diseases, and it contains the biotechnology INTACTA RR2 PRO®. It is resistant to stem canker, brown stem rot, an

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. A protein expression system for tandem affinity purification in Xanthomonas citri subsp. citri
Abstract Citrus canker, caused by the Gram-negative bacterium Xanthomonas citri subsp. citri (Xac), is one of the most devastating diseases to affect citrus crops. There is no treatment for citrus canker; effective control against the spread of Xac is usually achieved by the elimination of affected plants along with that of asymptomatic neighbors. An in dept

6. 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.

7. Specific boundaries between the causal agents of the soybean stem canker
Pathogens within the Diaporthe complex cause seed decay, stem blight and stem canker on soybean, representing a serious threat for this crop species. We herein utilize worldwide sequence data retrieved from Genbank in order to assess the species boundaries between the soybean stem canker causal agents, and define whether or not they should be regarded as mem

8. First report and characterization of Fusarium circinatum, the causal agent of pitch canker in Brazil
Pitch canker is one of the most important diseases of pine trees worldwide, including South America. The causal agent of this disease is Fusarium circinatum, a member of the Gibberella fujikuroi complex (GFC). In South America, the species is reported from Colombia, Uruguay and Chile, but is considered a quarantine organism in Brazil. In this study we charac

9. Detection and cellular localization of Xanthomonas campestris pv. viticola in seeds of commercial 'Red Globe' grapes
Commercial grapevine fruit (Vitis vinifera) of the Red Globe variety were collected in vineyards from Vale do São Francisco lower basin, an area of occurrence of grapevine bacterial canker. Seeds were extracted, classified as symptomatic or asymptomatic and processed in order to be observed under light (LM) and scanning electron microscopy (SEM) along with

10. New coffee (Coffea arabica) genotypes derived from Coffea canephora exhibiting high levels of resistance to leaf rust and Ceratocystis canker
The purpose of this study was to evaluate the resistance to coffee leaf rust (CLR) caused by Hemileia vastatrix and to Ceratocystis canker (Cc) in coffee genotypes derived from crosses of Coffea arabica var. Caturra with accessions of C. canephora backcrossed to Caturra. Twenty-three F3BC1 progenies including C. arabica var. Caturra and var. Colombia as cont

11. Análise econômica da prevenção e controle do cancro cítrico em São Paulo: uma aplicação da Análise Benefício-Custo / Economic analysis of the prevention and control of citrus canker in São Paulo: an application of Cost-Benefit Analysis
O cancro cítrico, considerado uma das mais importantes doenças da cultura dos citros, apresentou um drástico aumento de 607% no índice de talhões contaminados no Estado de São Paulo entre 2009 e 2011, mesmo diante da obrigatoriedade legal da erradicação das plantas sintomáticas. O aumento ocorre logo após mudança na legislação de controle e erra

12. Caracterização estrutural e funcional da proteína CsMAF1 de Citrus sinensis, parceira de interação do principal efetor tipo TAL de Xanthomonas citri / Structural and functional characterization of the Citrus sinensis protein CsMAF1, an interacting partner of the main type TAL effector of Xanthomonas citri
O cancro cítrico, causado pela bactéria Xanthomonas citri (X. citri), afeta a maioria das espécies de Citrus, ocorre praticamente em todos continentes e se destaca como uma séria ameaça à citricultura brasileira. O mecanismo molecular pelo qual X. citri causa cancro não é inteiramente conhecido, entretanto, sabe-se que a bactéria utiliza o sistema s
