Abstract. Zebua LI, Gunaedi T, Budi IM, Lunga N. 2019. The DNA barcode of red fruit pandan (Pandanaceae) cultivar from Wamena, Papua Province, Indonesia based on matK gene. Biodiversitas 20: 3405-3412. The red fruit pandan has been used by the people of Wamena in central highlands of Papua as medicinal plants, food ingredients, and religious ceremonies. Based on morphological characters, there are 39 cultivars of red fruit pandan in New Guinea. A standard method for plant species identification through DNA barcodes has been recommended to use matK gene. The research aimed to determine similarities in DNA barcode sequences of six red fruit pandan cultivars with its close relative that listed in NCBI system and to recommend the reliable DNA barcode for identification of this cultivar. Polymerase Chain Reaction was employed DNA to amplify matK gene fragments using an available forward primer (5’CGA TCT ATT CAT TCA ATA TTT C 3’) and reverse primer (5’TCT AGC ACA CGA AAGTCG AAG T 3’). The software BLAST, Bioedit, and ClustalX were used to analyze the data. Barcode DNA of red fruit pandan showed 1474 bp nucleotides sequence based on matK gene. An indication of six red fruit pandan cultivars showed that high similarity 99% with Pandanus conoideus Lam. It can be concluded that matK gene can be used to determine the species level in Pandanus.

Metode identifikasi spesies telah disepakati menggunakan barcode DNA standar yaitu gen rbcL dan gen matK. Tujuan penelitian ini untuk menentukan tingkat kemiripan sekuens barcode DNA tanaman Anggrek Payus Limondok (Phaius tancarvilleae) dengan spesies kerabatnya yang sudah terdata dalam BOLD Systems, merekomendasi penggunaan barcode untuk mengidentifikasi atau mengkonfirmasi spesies ini, dan mengamati variasi intraspesifik. Teknik Polymerase Chain Reaction (PCR) digunakan untuk mengamplifikasi sekuens gen rbcL dan matK melalui primer universal. Barcode rbcL menunjukkan kemiripan 100% (identik) dengan dua spesies berbeda dalam famili yang sama (Orchidaceae), sehingga tidak bisa diandalkan untuk identifikasi spesies P. tancarvilleae secara akurat. Sekuens matK sampel menghasilkan kemiripan 100% dengan spesies sama yang sebelumnya telah terdata dalam BOLD Systems. Kemiripan ini mengindikasikan rendahnya variasi genetik intraspesies tetapi sekuens matK dapat diandalkan untuk identifikasi atau konfirmasi spesies anggrek P. tancarvilleae. Kata Kunci: barcode, rbcL, matK, Phaius tancarvilleae Abstract Species identification methods convention have been recommended to use standard DNA barcode for plants; the rbcL and matK genes. The aims of this research were to determine similarities in barcode DNA sequences of Payus Limondok Orchid (Phaius tancarvilleae) with its close relatives that listed in BOLD Systems, to recommend the use of DNA barcodes for identification or confirmation of this species, and to observe intraspecific variations. Polymerase Chain Reaction technique was employed to amplify rbcL and matK genes using universal primers. The rbcL barcode of Payus Limondok resulted identical hit with other two different species in the same family (Orchidaceae), therefore, unreliable for accurate P. tancarvilleae species identification. The matK sequence of this plant was 100% similar with the same plant species listed in BOLD Systems. This similarity indicated low genetic variation within the species, but the matK sequence was found to be reliable for P. tancarvilleae orchid species identification or confirmation.

AbstrakMetode standar untuk identifikasi spesies tumbuhan melalui barcode DNA telah direkomendasikan untuk menggunakan dua gen plastida yaitu rbcL dan matK. Tujuan penelitian ini yaitu untuk menentukan tingkat kemiripan sekuens barcode DNA tanaman Anthurium Gelombang Cinta (Anthurium plowmanii) dibandingkan spesies kerabatnya yang sudah terdata dalam BOLD Systems dan untuk merekomendasi penggunaan barcode DNA yang bisa diandalkan dalam mengidentifikasi spesies ini. Teknik Polymerase Chain Reaction (PCR) digunakan dalam perbanyakan sekuens fragmen gen rbcL dan gen matK oleh primer universal yang tersedia. Hasil penelitian menyimpulkan bahwa sampel tanaman A. plowmanii menghasilkan sekuens barcode rbcL yang mirip 100% (identik) dengan spesies A. cubense. Ini berarti barcode DNA rbcL tidak dapat digunakan untuk identifikasi tingkat spesies. Sekuens barcode matK sampel menunjukkan kemiripan 99,1% dengan A. ravenii yang berbeda dalam morfologi daun. Sekuens matK sampel bersifat unik diantara anggota-anggota genus Anthurium sehingga direkomendasikam penggunaannya untuk identifikasi sampai tingkat spesies.Kata Kunci: barcode, rbcL, matK, Anthurium plowmaniiAbstractStandard method for plant species identification through DNA barcode has been recommended to use two plastids genes; the rbcL and matK.

Differentiation between Bursaphelenchus xylophilus and other related, non-pathogenic species can be ambiguous when based exclusively on morphological characters. The morphology of B. mucronatus and B. fraudulentus most closely resembles that of B. xylophilus. Moreover, all of these nematodes are found in both Asia and Europe and can colonise various species of pine. Therefore, for phytosanitary purposes it is necessary to identify the three species precisely and rapidly. We report the results of a multiplex PCR that utilises four primers to identify and discriminate the three Bursaphelenchus species simultaneously. The multiplex PCR yielded DNA fragments of 767, 305 and 132 bp, for B. xylophilus, B. mucronatus and B. fraudulentus, respectively. This primer combination has produced reliable results in multiplex PCR assays with a number of different populations of the listed species, and no cross-reactions were observed with other Bursaphelenchus species. The described approach is simple, reliable and cheaper than other molecular methods presently used for simultaneous identification of the above three species within the xylophilus group.
