DNA barcode as an effective tool for identification and reveal phylogenetic relationships in fish. The purpose of this study was to analysis DNA sequence, genetic distance and reveal phylogenetic relationships of stress resistance fish (blackfish) in Harapan Rainforest Jambi base on DNA barcode. The research was conducted from April to August 2016 in Harapan Rainforest Jambi, Integrated Laboratory, Jambi University and Biotechnology Laboratory of the Primate Study Centre-IPB University. DNA extraction was done on five blackfish species from Harapan Rainforest Jambi, namely Nandus nebulosus, Pristolepis grootii, Trichopodus leerii, Channa striata and Channa micropeltes. As a comparison, we used stress intolerance fish (whitefish) from Harapan Rainforest Jambi, i.e., Balantiocheilos melanopterus and Hemibagrus nemurus from the gene-bank NCBI with acession number KT001040,1. DNA Extraction was performed according to Quick-Star Tissue Protocol from Qiagen. COI gene amplification with modification at denaturation and anneling temperatures. Visualization DNA band using a horizontal electrophoresis machine from Bio Rad. Sequencing DNA send to 1st Base Malaysia. DNA sequence used Biodit and MEGA X software. The alignment of the DNA bands in MEGA X produces DNA sequence along 588 bp, where 350 bp conserve and 238 bp variable sites. The composition of the base nucleotides were (T/U) =29%, C=28.6%, A=25%, and G=17.3%. The closest genetic distance was between Channa striata and Channa micropeltes (0.190)  and the farthest was found on  Nandus nebulosus and  Hemibagrus nemurus (0.303). The phylogeny tree shows that the blackfishes are separated from whitefishes. The group of blackfish is divided into Channidae group (Channa striata, Channa micropeltes) and non-Channidae group (Nandus nebulosus, Trichopodus leerii, Pristolepis grootii).

Phylogenetic Framework

Samia ricini (Wm. Jones) and Samia cynthia (Drury) (Lepidoptera: Saturniidae) have been used as traditional sources of food as well as silk-producing insects. However, the phylogenetic relationship between the two silkworms remains to be addressed. In this study, the mitochondrial cytochrome c oxidase subunit 1 (COI) gene sequences corresponding to DNA barcodes from 13 Samia species were analysed, and a DNA barcode-based phylogenetic framework for these Samia species was provided. Phylogenetic analysis showed that multiple individuals of a species could be clustered together. Our analysis revealed a close relationship among Samia yayukae Paukstadt, Peigler and Paukstadt, Samia abrerai Naumann and Peigler, Samia kohlli Naumann and Peigler, Samia naessigi Naumann and Peigler, Samia naumanni Paukstadt, Peigler and Paukstadt, and Samia kalimantanensis Paukstadt and Paukstadt. The mixed clustering relationship and low Kimura-2-parameter (K2P) genetic distance (0.006) between individuals of S. ricini and Samia canningi (Hutton) indicated that the cultivated silkworm S. ricini was derived from the non-cultivated silkworm S. canningi. The remote phylogenetic relationship and high K2P genetic distance (0.039) indicated that S. ricini and S. cynthia are distinct species, thus providing solid molecular evidence that they had entirely independent origins. The relationships between S. kalimantanensis and S. naumanni and between S. cynthia and Samia wangi Naumann and Peigler, as well as the potential cryptic species within S. abrerai were also discussed. This is the first study to assess the DNA barcodes of the genus Samia, which supplements the knowledge of species identification and provides the first molecular phylogenetic framework for Samia species.

The wild betta fish is a potential ornamental fish export commodity normally caught by traders or hobbyists in the wild. However, the population of wild betta in nature has declined and become a threat for their sustainability. This research was conducted to analyze the genetic diversity, phylogenetic relationships, and molecular identification through DNA COI gene sequence of Indonesian wild betta fish. A total of 92 wild betta fish specimens were collected in this study. Amplification of COI genes was carried out using Fish F1, Fish R1, Fish F2, and Fish R2 primers. The genetic diversity and phylogenetic relationships were analyzed using MEGA version 5 software program. Species identification of the specimen was conducted using BLAST program with 98-100% similarity value of the DNA sequences to indicate the same species. Phylogenetic tree construction showed seven monophyletic clades and showed that Betta smaragdina was the ancestral species of genus Betta in Indonesian waters. Genetic distance among species ranged from 0.02 to 0.30, whereas intra-species genetic distance ranged from 0 to 6.54.

Abstract. Trisyani N, Rahayu DA. 2020. DNA barcoding of razor clam Solen spp. (Solinidae, Bivalva) in Indonesian beaches. Biodiversitas 21: 478-484. Solen spp. are shells with various morphological characteristics with a wide distribution of tropical and subtropical beaches, including Indonesia. The identification of Solen spp. is generally based on its morphological characteristics. This method is very problematic due to specimens share similarity in morphology and color. This study was using DNA barcode as a molecular identification tool. The bivalve COI sequence was amplified using PCR and molecular phylogenetic analysis using the Neighbor-Joining method. The amplified COI gene has a length of about 665 bp. The purpose of this study was to evaluate genetic variation and compare the phylogenetic Solen spp. in Indonesian waters. The composition of the nucleotide bases of Solen spp. the comparative species are A = 26.79%, C = 23.16%, G = 19.17% and T = 30.93%. The total nucleotide base A + T was 57.72%, while G + C was 42.33%. The results of phylogenetic analysis showed that Solen spp. Cirebon and Jambi are in one clade with Solen regularis with genetic distance 0.000 - 0.002. Solen spp. Surabaya, Bangkalan, Pamekasan, and Sumenep are in separate clades and are related to Solen grandis, Solen stricus and Solen lamarckii with genetic distance from 0.146 - 0.156. The diversity of nucleotide was 0.9780 and was divided into 12 haplotypes.

A new pill millipede, Rhopalomeris nagao sp. nov., is described from Vietnam. It is recognized by the following combination of characters: antennal tip with numerous sensory cones; telopods with short prefemoral and femoral trichosteles, with long, straight and acute tuberculiform femoral process, and with shorter lobuliform tibial process; syncoxial lobe being slightly concave medially, syncoxial horns being longer than lobe. A fragment of the cytochrome c oxidase subunit I (COI) gene is also provided for the new species. The K2P genetic distance of the COI between the new species and other Vietnamese glomeridans is from 10.7% to 16.9%. Two genera, Hyperglomeris and Hyleoglomeris, are considered to be non-monophyletic, but more data and samples will be needed for confirmation.

A large number of gastropod species have similarities in morphology (cryptic) makes misidentification probably happen/occurred. Accurate species identification is needed in studying bioecology of species. This research aims to identify the species of Cassidulla sp. Which was collected from Peyum Beach Merauke with DNA barcoding techniques using COI gene markers. The primers used in this study are forward primers (LCO1490) and reverse primers (HCO2198). The result of identification with DNA barcoding showed that the species analyzed was Cassidula angulifera with a 99.53% similarity level with a DNA sequence length of 650 bp. Phylogenetic reconstruction showing the entire sequence of Cassidula sp. which were analyzed separately based on the type and genetic distance with high bootstrap value. Phylogenetic reconstruction of Cassidula sp. form a monophyletic group, which means that the species come from the same ancestors. DNA barcoding is very good and accurate in identifying species.

<p>Kuantan cattle is one of local beef cattle breed of Riau Province which its origin was unknown. Kuantan cattle are commonly found in Indragiri Hulu and Kuantan Singingi Regency. Based on phenotype characterizations, kuantan cattles are similar with pesisir cattle (West Sumatera beef cattle). Historically, kuantan cattle were pesisir cattle brought by “minang” immigrants (Immigrant from West Sumatera) to this region. The purpose of this study was to analyze the origin of the kuantan cattle through genetic diversity analysis using DNA barcode. DNA barcode used was Cytochrome oxidase subunit I gene which was found in the mtDNA. DNA isolation was done on 25 kuantan’s blood samples and 18 pesisir blood samples. Amplification of COI gene segment used Polymerase Chain Reaction technique. The forward primer sequence used in this study was F’5 TTCTCAACCAACCATAAAGATATTGG-3’ and the reverse primer sequence used was reverse 5’-TAGACTTCGGGGTGTCCAAAGAATCA-3. It squeezed kuantan and pesisir sequence 5711 - 6420 base (GeneBank accession number NC_005971) with length by 710 bp. Analysis result of sequence using MEGA 5.2 Program showed that there were 6 polymorphic sites establishing 7 haplotypes on kuantan cattle and 9 polymorphic sites establishing 12 haplotypes on pesisir cattle. Based on genetic distance and phylogeney tree, kuantan and pesisir cattle were in same group with <em>Bos indicus</em>. Mutation in the COI gene segment in this study was too small and was not able to distinguish the difference of those breeds. The result of neighbor joining analyze indicated that kuantan cattle origin was from <em>Bos indicus</em> just like pesisir cattle.</p><strong>Key Words: </strong>COI Gene, Polymorphic, Kuantan Cattle, Genetic Distance, Phylogenetic Tree
