TEKNIK PCR ITS-RFLP UNTUK SELEKSI ISOLAT JAMUR PADA PENGUJIAN AGEN PENGENDALI HAYATI PADA SERANGAN GANODERMA TANAMAN Acacia mangium

Abstract

In vivo control activities test of BCA candidate is required to evaluate its effectiveness. This test involved  identification of the fungal species that inhabited the experimental plant after inoculation of BCA and  pathogen. Identification of inhabitant fungi in the BCA control activity test can be conducted by culturing the fungi on artificial media. Fungal species can be identified based on morphological characters or genetic  characters of fungal culture. This study was conducted to determine the potential of PCR ITS-RFLP molecular  markers in the initial selection process of fungal isolates before identification based on DNA sequences and to  select the enzyme that produce polymorphic PCR ITS RFLP pattern. Three enzymes (DraI, EcoRI and HinfI)  were successfully separated 8 fungal cultures used in this study into three groups based on the pattern of PCR  ITS DNA, while five other enzymes (BamHI, BclI HaeII, HpaI, and HindIII) were failed to cut the DNA ITS  fragments, except for one isolate.
