Variabilidad genética y epigenética

De Mendoza CONICET

El género Solanum presenta una gran variabilidad genética y la papa cultivada tiene mas de 200 especies silvestres emparentadas. En el Laboratorio estamos interesados en analizar la variabilidad genética y epigenética de las especies silvestres de papa. Por otro lado, utilizamos marcadores moleculares aplicados al mejoramiento vegetal.
