    Soil-borne wheat mosaic virus - SBWMV, agente causal da virose que se caracteriza, em termos econômicos, como uma das mais importantes enfermidades da cultura de trigo, pode também infectar uma vasta gama de gramíneas. Com o objetivo de conhecer as alterações metabólicas promovidas pelo mosaico do trigo, foram analisados os teores de açúcares totais e a concentração de prolina e determinou-se a atividade da nitrato redutase. O experimento foi conduzido na área experimental da Embrapa Trigo, usando cinco genótipos de trigo (BRS Guabiju, BRS 194, BRS 179, BR 23 e PF 980524) com diferentes níveis de resistência ao SBWMV. As determinações bioquímicas foram realizadas 45 dias após a emergência de plantas. A atividade da nitrato redutase foi mais elevada em plantas sem sintomas, quando comparada às com sintomas. Os níveis de açúcares e de prolina foram mais elevados em plantas com sintomas do que nas sem sintomas. Os resultados encontrados comprovam as alterações metabólicas promovidas pelo SBWMV nos cinco genótipos de trigo testados.<br>Soil-borne wheat mosaic virus - SBWMV causes substantial economic losses to the wheat crop and can also infect a wide range of grass crops. An experiment was conducted in the experimental area of Embrapa Trigo, using five genotypes of wheat (BRS Guabiju, BRS 194, BRS 179, BR 23, and PF 980524) with different resistance levels to SBWMV. Samples were collected 45 days after emergence, and levels of sugars, proline concentration, and nitrate reductase activity were biochemically analyzed to understand the metabolic alterations induced by SBWMV. Nitrate reductase activity was higher in asymptomatic plants, as compared to the level observed in plants with symptoms. Sugar and proline levels were higher in plants with disease symptoms than in asymptomatic plants. The results show that the metabolic changes were caused by the SBWMV in the five different genotypes used in the experiment
