Se recuperaron aislados de tejidos sintomáticos de hojas de naranjilla Solanum quitoense Lam. en la provincia de Pastaza, una región de producción importante de la región amazónica del Ecuador. Se identificaron hongos filamentosos por medio de técnicas moleculares basados en la región ITS y secuenciamiento de ADN ribosomal. De un total de 68 hongos, se recuperaron 14 taxa. La mayor cantidad de registros pertenecieron a las especies Diaporthe citri, D. schini, y Xylaria berteri. Según lo que conocemos, más del 90% de los taxones recuperados en este estudio se reportan por primera vez en S. quitoense. Los indices de diversidad sugieren que los tejidos sintomáticos representan un reservorio moderadamente diverso para especies de hongos. Por lo tanto, dichas lesiones representan una fuente significativa de moléculas con propiedades agronómicas y farmacéuticas, considerando su capacidad para sobrevivir en tejidos foliares sintomáticos. Esperamos que este estudio facilite las medidas de control biológica en cultivos neotropicales de interés comercial.
