| One of the fungal pathogens that causes more agriculture damage is Botrytis cinerea. Botrytis is a constant threat to crops because the fungus infects a wide range of host species, both native and cultivated. Furthermore, Botrytis persists on plant debris in and on the soil. Some of the most serious diseases caused by Botrytis include gray mold on vegetables and fruits, such as grapes and strawberries. Botrytis also causes secondary soft rot of fruits and vegetables during storage, transit and at the market. In many plant-pathogen interactions, resistance often is associated with the deposition of callose, accumulation of autofluorescent compounds, the synthesis and accumulation of salicylic acid as well as pathogenesis-related proteins. Arabidopsis... |

| Abstract: The objective of this work was to evaluate the effect of the Y-trellis (YT) and vertical shoot-positioned (VSP) training systems on the incidence and severity of Botrytis cinerea, on cluster compactness, and total polyphenol (TP) contents of 'Sauvignon Blanc' grapevine in the municipality of São Joaquim, in the state of Santa Catarina, Brazil. Field trials were carried out in a randomized complete block design during the 2013/2014 and 2014/2015 crop seasons, with assessments performed at harvest. The YT system causes a higher incidence and severity of botrytis bunch rot under climatic conditions favorable to the pathogen, as well as greater cluster compactness, than the VSP system, without affecting the content of total polyphenols of 'Sauvignon... |

| Botrytis cinerea is a necrotrophic pathogen causing pre- and post-harvest diseases in at least 235 plant species. It manifests extraordinary genotype and phenotype variation. One of the causes of this variation is transposable elements. Two transposable elements have been discovered in this fungus, the retrotransposon (Boty), and the transposon (Flipper). In this work, two complete (Boty-II-76 and Boty-II-103) and two partial (Boty-II-95 and Boty-II-141) long terminal repeat (LTR) retrotransposons were identified by an in silico genomic sequence analysis. Boty-II-76 and Boty-II-103 contain 6439 bp nucleotides with a pair of LTRs at both ends, and an internal deduced pol gene encoding a polyprotein with reverse transcriptase and DDE integrase domains. They... |

| O uso de indutores de resistência em plantas representa um método alternativo e promissor no controle de podridões pós-colheita de frutos. Assim sendo, foi conduzido um experimento na Universidade Tecnológica Federal do Paraná - Câmpus Dois Vizinhos - PR, no ano de 2004, com objetivo de avaliar a aplicação pré-colheita de quitosana e acibenzolar-S-metil (ASM) sobre o comportamento pós-colheita de frutos de morangueiro da cultivar Aromas. O efeito da aplicação de quitosana (0,5; 1,0 e 2,0%) e de uma dose de ASM (0,0025%) foi verificado em relação à testemunha (água destilada) e ao tratamento-controle com aplicação de fungicidas. A aplicação na pré-colheita de quitosana, nas três doses avaliadas, retardou a maturação dos frutos, manteve maior firmeza de... |

| El sector agrícola, y particularmente la producción de hortalizas tiene una importancia singular en la agricultura, a nivel mundial y nacional, al considerarse que éstas ocupan el segundo lugar de los productos agropecuarios. Las enfermedades fúngicas son una de las principales causas de pérdidas en hortalizas durante el período de almacenamiento, disminuyendo su valor nutricional, calidad y precio de venta. Generalmente las hortalizas se exponen a diversos tratamientos con productos químicos antes de su almacenamiento; esto contribuye a que las poblaciones de hongos sean cada vez más resistentes, y por lo tanto más difícil de controlar. Ante esta situación es necesario realizar trabajos de investigación que permitan encontrar las sustancias químicas para... |

| Lilium polyphyllum is a critically endangered herb in the wilds of Uttarakhand, India. Gray mold appeared as a new disease on this species from July to August (2008-2009) causing death of inflorescences and shoots. Botrytis cinerea was consistently isolated on PDA, from infected inflorescences. Pathogenicity was established by inoculation of potted plants of L. polyphyllum in a glasshouse. Botrytis cinerea was recorded as a gray mold pathogen on L. polyphyllum for the first time in India, causing flower and shoot blight. Tis disease may seriously afect reproductive stages of this endangered host. To our knowledge, B. cinerea had not been reported previously on L. polyphyllum. |

| Botrytis cinerea is a filamentous plant pathogen of a wide range of plant species, and its infection may cause enormous damage both during plant growth and in the post-harvest phase. We have constructed a cDNA library from an isolate of B. cinerea and have sequenced 11,482 expressed sequence tags that were assembled into 1,003 contigs sequences and 3,032 singletons. Approximately 81% of the unigenes showed significant similarity to genes coding for proteins with known functions: more than 50% of the sequences code for genes involved in cellular metabolism, 12% for transport of metabolites, and approximately 10% for cellular organization. Other functional categories include responses to biotic and abiotic stimuli, cell communication, cell homeostasis, and... |

| Abstract: The objective of this work was to evaluate cold storage periods and postharvest longevity of the seedless table grape 'BRS Vitória' subjected to the application of the disease-resistance inducer acibenzolar-S-methyl (ASM). Bunches were treated or not with 1% ASM, placed individually in plastic clamshell trays and stored in a cold chamber at 2±1ºC, at a high relative humidity, for three periods (30, 45, and 60 days), followed by a 5-day period of shelf life in plastic clamshells, at 22±2ºC. After each storage period, gray mold (Botrytis cinerea) incidence was evaluated, and the physicochemical analysis was performed. A completely randomized design, with four replicates, was used in two 2x3 factorial arrangements: one evaluating ASM application and... |

| ABSTRACT: In recent years "redness" has increasingly appeared in strawberry plants with leaves taking on a reddish color. No causal agent has been associated with plants. Since strawberries presented problems due to the incidence of nematodes, the purpose of this study was to look at the relationship between production, resistance to the Meloidogyne hapla nematode and the "redness" symptom in strawberry cultivars. Two experiments were performed, both with the 'Camino Real', 'Festival', 'Oso Grande', 'Albion' and 'Camarosa' cultivars. The first experiment was performed in the field, where the following were evaluated: strawberry production, fruit quality, macro and micronutrient contents in fruit and leaves, percentage of plant survival, incidence of... |

| Propolis has been used for millennia for its antimicrobial and pharmaceutical properties, whereas its use as an agricultural antifungal agent has only recently been assessed. The chemical characteristics of six ethanolic extracts of Chilean propolis (EEP-1 to EEP-6) were evaluated. The total polyphenols ranged between 7.8 and 42.3 mg mL-1 equivalents of a 2:1 pinocembrin: galangin standard, and the total flavonoid contents ranged between 4.0 and 19.7 mg mL-1 equivalents of quercetin. A high-performance liquid chromatographic (HPLC) analysis allowed the identification of caffeic acid, myricetin, quercetin, kaempferol, apigenin, pinocembrin, galangin, caffeic acid phenethyl ester (CAPE) and rutin. The EEP-3 extract was selected for additional studies based... |

| The plant hormone abscisic acid has huge economic potential and can be applied in agriculture and forestry for it is considered to be involved in plant resistance to stresses such as cold, heat, salinity, drought, pathogens and wounding. Now overproducing strains of Botrytis cinerea are used for biotechnological production of abscisic acid. An LTR retrotransposon, Boty-aba, and a solo LTR were identified by in silico genomic sequence analysis, and both were detected within the abscisic acid gene cluster in B. cinerea B05.10, but not in B. cinerea SAS56. Boty-aba contains a pair of LTRs and two internal genes. The LTRs and the first gene have features characteristic of Ty3/gypsy LTR retrotransposons. The second gene is a novel gene, named brtn, which... |

| Com base em dados de infecção natural avaliou-se a incidência do mofo-cinzento, causado por Botrytis cinerea, em 14 clones de Eucalyptus spp. em relação às condições climáticas predominantes em um viveiro clonal localizado em Belo Oriente, Minas Gerais. A temperatura máxima, mínima e média, precipitação pluviométrica e umidade relativa do ar foram coletadas entre 1991 e 2004. A incidência da doença foi avaliada mensalmente em 2004 em todas as fases de produção de mudas clonais de eucalipto. A presença do patógeno foi avaliada na água coletada do efluente de fertirrigação. A incidência do mofo-cinzento correlacionou-se melhor e negativamente com a temperatura máxima. Os resultados indicaram que a temperatura máxima é a variável a ser monitorada para fins de... |
