Abstract

Abstract : Esteya vermicola is an endophytic fungus of pine wood nematode with demonstrated biocontrol efficacy. At present, the methods for detection of this fungus from pine wood is still inconvenient and inefficient such as thin‐section microscopic observations. In the present study, a simple protocol was developed for wood sample preparation for effective extraction of fungal DNA from wood samples for PCR detection. The protocol of preparation of the sample involves washing in sterile water overnight on a shaking table followed by filtration and centrifugation to obtain the extracted DNA. The result indicates that with this sample preparation protocol, any proper DNA extraction method can be effectively used for the rapid and reliable detection of E. vermicola from pine wood. This method can provide valuable support for follow‐up studies with practical applications, such as investigation of the growth rate of E. vermicola and how long it remains viable inside a pine tree.
