O RIoGrande do Sul é o maior produtor de pêssegos do pais. Dentre as doenças que afetam esta cultura, os viróides, descritos como menores e mais simples fitopatógenos conhecidos, podem causar substanciais danos à produção e à qualidade de frutos. Peach latent mosaic víroid (PLMVd) é a espécie-tipo do gênero Pelamoviroid, responsável pelo envelhecimento precoce das plantas e produção de frutos irregulares. |

O mosaico comum é uma importante doença viral da cultura do trigo, sendo atribuído ao Soil-borne wheat mosaic virus (SBWMV - Furovirus) e Wheat spindle streak mosaic virus (WSSMV - Bymovirus), ambos transmitidos por Polymyxa graminis. A doença ocasiona reduções significativas de produtividade se cultivares suscetíveis forem semeadas em áreas com a presença do vetor e em condições favoráveis como inverno frio e úmido (Lau, 2014). |

Soil-borne wheat mosaic disease (SBWMD) caused by wheat stripe mosaic virus (WhSMV) is one of the most important viral diseases of wheat in Brazil. Farmers have used crop rotation (CR) successfully to reduce the incidence of many diseases in wheat. CR can contribute along with genetic resistance in the management of SBWMD. The objective of this study was to evaluate the effect of CR in SBWMD incidence and wheat yield as compared with wheat monoculture (W). During 2017 and 2018 growth seasons, in a long-term experiment, W and three CR: W1 ? white oats-wheat; W2 ? vetch-white oats- wheat; and W3 ? black oatsbarley-black oats-wheat were evaluated using three wheat cultivars: BRS Parrudo (resistant), BRS Reponte (moderately resistant) and BRS Guamirim... |

Rice (Oryza sativa L.) is an important food crop for humanity, being cultivated in tropical and temperate regions of the world. This study reports the nearly complete genome sequences of four Brazilian rice stripe necrosis virus (RSNV) isolates. The nucleotide sequences of the RNA1 and RNA2 genome segments of these Brazilian isolates were 96.5 to 99.9% identical, indicating their close phylogenetic relationship to each other. Phylogeny and recombination analysis indicated that the genome of one of the isolates consisted of RNA segments of different origins, suggesting that a reassortment event had occurred. |

Physalis rugose mosaic virus (PhyRMV) causes severe damage to Physalis peruviana L., affecting vegetative parameters, fruit quantity and quality. The aim of this study was to perform a molecular characterization of PhyRMV associated with P. peruviana from commercial fields in the municipality of Lages, Santa Catarina State, Southern Brazil, and to evaluate its transmission by seeds. Plants displaying mosaic, dwarfism, and leaf malformation symptoms were collected from P. peruviana. Double-stranded RNA was extracted and submitted to cDNA library synthesis and high-throughput sequencing (HTS). For the virus transmission assay, seeds from PhyRMV-infected plants were used, and viral infection in seedlings was verified using symptomatic and molecular diagnosis.... |

The epidemiology of Entomosporium leaf spot (ELS) affecting European pear is poorly understood, which limits the development of an effective management strategy. In vitro assays were conducted to study the effect of temperature levels (5, 10, 15, 20, 25, and 30 °C) on Diplocarpon mespili conidial germination evaluated at different incubation times (0, 2, 4, 6, 8, 12, 24, and 48 h). Inoculation experiments were conducted to assess the effect of leaf wetness duration (0, 6, 12, 24, and 48 h) under constant temperature (20 °C) on ELS disease severity on leaves of cultivar ?Rocha?. The temperature × time interaction significantly affected conidial germination in both experiments and a response surface model was fitted to percent conidial germination data. The... |

Abstract: In Brazil, wheat (Triticum aestivum) is cultivated mainly in the southern part. The soilborne wheat mosaic disease (SBWMD), caused by the wheat stripe mosaic virus (WhSMV), is one of the most important viruses in the region. Its diagnosis is based mainly on symptoms since molecular techniques are expensive, especially for RNA genomes viruses. However, serological tests using IgY immunoglobulins are highly efective in identifying viruses. This study aimed to produce and characterize a polyclonal antibody capable of interacting with the WhSMV capsid protein. The gene encoding the virus capsid protein was inserted into the expression vector pET-15b; the transformation and expression occurred in Escherichia coli BL21::DE3 in vitro. The recombinant... |

Cowpea mild mottle virus (CpMMV), the causal agent of stem necrosis disease, has drawn attention of soybean producers in recent years due to yield losses in the main producing regions of Brazil. Serological methods for viral detection require the use of an antiserum of good quality to achieve specificity and sensitivity. The entire coat protein gene of a Brazilian CpMMV isolate was cloned into a bacterial expression vector and transformed into Escherichia coli BL21::DE3 for in vitro expression. The coat protein, fused to a His-tag, was purified under denaturing conditions by affinity chromatography using a Ni-NTA resin. After renaturation, the integrity and identity of the purified recombinant protein was confirmed by SDS-Page and MALDI-ToF/ToF mass... |
