Cím:	Potential of local hypovirulent strains of Cryphonectria parasitica for biological control of chestnut blight disease / Mariem Boukhili, Arnold Szilágyi, Gábor Tarcali, Kitti Csüllög
Dátum:	2023
Megjegyzések:	139 in the region had been continuously increasing and in 2022 it reached more than 28,000. The use of the traps increased the efficiency of pesticide use over 16,000 hectares of the region, which resulted in an additional profit of 30-50 US dollars/hectare/year. Further studies on the pest populations and the use of beneficial organisms instead of pesticides may lead to further increases in efficiency and help to protect human health and local biodiversity. Chestnut blight canker is a serious disease caused by the Ascomycota fungus Cryphonectria parasitica. The presence of the hypovirulent form of the fungus was involved in the recovery of the chestnut blight disease in many countries worldwide. The present studies focus on a specific site in Hungary: Farkasgyepű (Veszprém county) in which 44% of the samples were hypovirulent. Two vegetative compatible groups were detected, the first group contains FG3, FG8, FG10, and FG12 and the second contains FG5, FG6, and FG7. FG2 and FG4 were considered as bridge samples. The potential of the hypovirulent strains was detected through their ability to convert 80% of the virulent strains into hypovirulent and this was acquired by the transfer of the dsRNA from the hypovirulent strains to the virulent isolates. The presence of the dsRNA in the cytoplasm of hypovirulent isolates was confirmed through the dsRNA extraction and the electrophoresis method. As a result, the presence of dsRNA confirmed the white phenotype of the hypovirulent samples. Furthermore, Farkasgyepű has not been treated
