Abstract

Austropuccinia psidii is a pathogenic fungus that causes rust in the Myrtaceae plant. The extensive plantation of the host of this fungus has increased the attack of fungal pathogen, therefore, will increase the threat to the presence of Myrtaceae species around the globe including in Indonesia. This present study was aiming to detect and identify the presence of this pathogen by morphological and molecular observation. Morphological observation revealed the presence of A. psidii urediniospores on salam (Syzygium polyanthum) and kayu putih (Melaleuca cajuputi) leaves collected from the arboretum of the Indonesian Center for Forest Biotechnology and Tree Improvement (CFBTI), and the presence of teliospores on young Syzygium leaves. PCR amplification using specific primers of Ppsi1 / Ppsi6 succeeded in detecting the presence of A. psidii fungi Melaleuca and Syzygium showed by DNA amplicon length around 500bp. Efforts to obtain ITS DNA sequences to compare the molecular characteristics of fungi from two different hosts have been carried out, however, the sequencing electropherogram was unreadable, so the comparison can not be performed. This study reported that A. psidii is currently present in Myrtaceae species in Yogyakarta, therefore precaution efforts should be conducted to avoid economic and ecological impact from this pathogen.

Abstract

Root rot caused by Ganoderma philippii (Bres. & Henn. ex Sacc.) Bres., is an important disease in Acacia plantation. A strategy to control this disease is currently being developed, particularly on the application of biological control agent (BCA). Species specific primers for rapid identification of potential fungi as BCA were developed. This study aimed to obtain the best DNA condition and the best primers for species specific identification. DNA with 20x dilution is the best condition for amplification of the ITS fragment thus used for rapid species identification. The best primer set to detect Cerrena sp. is CrF1/CrR1, PbF2/PbR2 is the best primer set for Phlebiopsis sp. 1. There was no specific primer suitable to detect Phlebia sp. 1 and Phlebia sp. 2 only but Pl-2F1/Pl-2R4 is the best primer set for Phlebia spp.

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.
