1. A survey of RNA genome viruses in Lima bean crops of Northeastern Brazil
ABSTRACT Lima bean plants showing mosaic and leaf distortion symptoms, similar to those induced by viruses, were observed in several production areas in the states of Ceará and Piauí, Northeastern Brazil. The aim of this study was to identify RNA genome viruses that infect lima bean. Field research was conducted from 2017 to 2018. Fifty-five symptomatic sa

2. Procedure for detecting tobamovirus in tomato and pepper seeds decreases the cost analysis
ABSTRACT The transmission of tobamovirus by tomato and pepper seeds is an important mean of virus introduction in crops. Therefore, detecting its presence in the seed becomes essential for the preventive control of virus diseases. In this study, a method was proposed for the detection of Tobacco mosaic virus (TMV) and Tomato mosaic virus (ToMV) in tomatoes (

3. Rbc2, a new dominant gene for resistance of soybean to Cowpea mild mottle virus: Inheritance and mapping
Abstract The objective of this work was to study the inheritance of soybean resistance to Soybean Steam Necrosis (SSN) and to map the resistance gene(s), using an F2 population from the cross between the soybean cultivars BRS 133 (resistant) and CD 206 (susceptible). A phenotypic evaluation was performed under controlled conditions, in a greenhouse. In a pop

5. Washing treatment impact on print quality of screen printed knitted fabrics
ABSTRACT The surface of textile materials is highly textured, commonly in non-uniform ways. Because of this texture effect, textile surface appears rougher and more porous than other printing substrates, which can cause excessive ink penetration during printing process. Next, washing process is very important factor because it influences ink characteristics

7. Herança da tolerância da soja ao Cowpea Mild Mottle Virus
A necrose da haste em soja é causada pelo vírus Cowpea mild mottle virus (CPMMV) e é considerada uma doença emergente e economicamente importante no Brasil. Apenas cultivares tolerantes foram identificadas até o momento, e o controle genético da tolerância permanece desconhecido. Para estudar a herança da tolerância ao CPMMV foram realizados dois cr

8. Identificação e caracterização molecular de isolados brasileiros de Carnation mottle virus em craveiros
Carnation mottle virus (CarMV) foi identificado em craveiros com e sem sintomas, pelo círculo de hospedeiras, teste sorológico e analise molecular da capa proteica do genoma viral. Sete amostras foram avaliadas por testes biológicos e sorológicos. Duas delas, uma proveniente de São Paulo e outra de Minas Gerais, que apresentaram os maiores valores de a

9. Occurrence and molecular characterization of Cucumber green mottle mosaic virus in cucurbit crops of KPK, Pakistan
Field survey of the cucurbit crops revealed a high incidence of Cucumber green mottle mosaic virus (CGMMV) in Khyber Pakhtunkhwa Province (KPK), Pakistan. Among the seven districts surveyed, average percent incidence of CGMMV was recorded up to 58.1% in district Nowshera, followed by 51.1% in district Charsada, 40.5% in district Swabi and 37.3% in district M

10. Aphelenchoides besseyi Christie (Nematoda: Aphelenchoididae), agente causal del amachamiento del frijol común
Identification of the causal agent of the disease "amachamiento" of common bean was carried out using four tests: analysis of double strand RNA (dsRNA) of viral origin, DAS-ELISA technique, applying Koch's postulates and the pathogenicity test. The analysis to detect dsRNA brought about two bands of approximately 1100 and 3200 bp, a similar pattern of bands

11. Production of polyclonal antiserum against Cowpea mild mottle virus coat protein and its application in virus detection
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 Bra

12. Identificação de isolados do Sida mottle virus e Sida micrantha mosaic virus não transmissíveis por Bemisia tabaci biótipo B que infectam maracujazeiros (Passiflora edulis f. flavicarpa) / Identification of Sida mottle virus and Sida micrantha mosaic virus isolates non transmissible by Bemisia tabaci biotype B infecting passionflower (Passiflora edulis f. flavicarpa)
Doenças causadas por virus do gênero Begomovirus (família Geminiviridae) são incomuns em espécies de passifloras. Nos últimos dez anos, entretanto, foram encontrados no Brasil begomovirus infectando passifloras em pomares nos municipios de São Fidelis (RJ), Paragominas (PA), Patos de Minas (MG) e Araguari (MG). Estes isolados foram transmitidos mecani
