Ocurrencia natural del hiperparásito ampelomyces quisqualis en ambientes urbanos del noroeste argentino

Abstract

Platanus x acerifolia (Aiton) Willd, conocido localmente como “Plátano” es una especie utilizada asiduamente en el arbolado urbano de las ciudades de la Argentina. Durante el 2023, en lugares de esparcimiento, calles y otras áreas urbanas y rurales de la Provincia de Tucumán se observó una enfermedad que afectaba el follaje de este árbol. A partir del estudio morfológico de los estadios asexuales, así como el hospedante, se determinó el agente causal como Erysiphe platani (Howe) U. Braun & S. Takam (Erysiphaceae). A su vez, se identificó otro pequeño hongo creciendo particularmente hacia el borde de las laceraciones. En las muestras estudiadas observadas al microscopio se encontraron abundantes estructuras globosas a piriformes afectando las hifas, células basales, conidióforos y conidios de E. platani causando alteraciones y deformaciones. Las mismas se identificaron como picnidios de Ampelomyces quisqualis Ces. (Phaeosphaeriaceae), un hiperparásito de importancia ecológica y económica que está ampliamente distribuido en todo el mundo. Este hallazgo se considera como la primera aparición natural de este parásito interfúngico en la región. Nuestros resultados indican que A. quisqualis muy probablemente establece una interacción parasitaria oportunista con el mildiú, siendo el huésped un reservorio en condiciones naturales.
