Abstract

Tridacna crocea and T. maxima are relatively abundant in the Indonesian coral reef. These two species are, however, under high presure due to exploitation for food, industry, and aquarium trade.  It is, therefore, necessary to understand their biology, such as genetic variability within and between populations, before utilizing them for strain improvement and restocking, prior to the extinction of the populations of T. crocea and T. maxima.  Here we amplified a length of 456 bp of the mitochondrial DNA cytochrome c oxidase I gene from Tridacna crocea and of 484 bp from T. maxima to asses the genetic variability within and between populations of both species.  The results showed that both species have high genetic diversity and polymorphism within each local population. This provides a sufficient basis for selection of improved strain of T. crocea and T. maxima for mariculture. However, if the genetic variation led to genetic differentiation among populations due to the result of evolutionary adaptation, mixing genetically different populations may result in the break up of co-adaptation gene complexes.  This might result in the loss of the physiological capacities of the parental populations.

Abstract

Subterranean termite Coptotermes spp. has been known as the most economically important structural pest in Indonesia. Due to morphological ambiguity, traditional identification of Coptotermes spp. has always been difficult and unreliable.  Through molecular diagnostic method, a study was conducted to determine genetic variation of Coptotermes spp. occurring in Java Island.  Termite specimens were collected from Banten 1, Banten 2, DKI 1, DKI 2, Jabar 1, Jabar 2, Jateng 1, Jateng 2, Yogya 1, Yogya 2, Jatim 1, and Jatim 2.  The method for identification was PCR-Restriction Fragment Length Polymorphism (PCR-RFLP) analysis using four restriction enzymes each of which was applied to CO II amplicon for all the Coptotermes spp. being analyzed.  The results showed the existence of two species of Coptotermes in Java which are different from both Coptotermes gestroi and Coptotermes formosanus.

Abstract

A study on sequence variation in the mitochondrial DNA of Trochus niloticus has been conducted. Polymerase chain reactions (PCR) technique was applied to amplify cytochrome c oxidase I gene of 533 bp and ABI 310 aotomatic DNA sequencer was used to sequence the PCR product.  This study was aimed to know the genetic variation of T. niloticus and the suitability of partial sequence of cytochrome c oxidase I gene as a molecular marker in the genetic study.  The results showed that from two T. niloticus specimens, 12 polymorphic sites were detected yielding 2 haplotypes. This indicated a highly genetic variation in thecytochrome c oxidase I (COI) gene of T niloticus.  In addition, cytochrome c oxidase I gene was proved to be a suitable marker for the genetics studies of various species of organisms.

Abstract

Anoa is an endemic ungulate in Sulawesi and its status now is endangered because the population continues to decline. Conservation genetics is one of the crucial issues in the anoa conservation strategy and action plan 2013-2022 document, but this genetic data is not yet available. To investigate and provide valuable information for conservation genetics measures, thirteen polymorphic microsatellites were used to analyze 20 adult anoa. Anoa has relatively low genetic diversity within populations (HO = 0.58), and high genetic differentiation among populations (FST = 0157). Although the anoa population has a bottleneck signal (T.P.M: 0.019; P0.05), the bottleneck simulation results show that the loss of genetic diversity is being slow over the next 100 years (9.5%). We provide some recommendations for conservation genetics based on the findings in this paper, including monitoring and genetically mapping for other anoa populations due to bottleneck signals, establishing the founder of the ex-situ population by examining their genetic diversity status, maintaining and increasing the number of individuals in the ex-situ population to genetically safe population size, and managing anoa populations by avoiding inbreeding. In-situ and ex-situ conservation programs should be combined to maintain the genetic diversity of anoa.

Abstract

The cynomolgus monkey (Macaca fascicularis) is one of the most common nonhuman primates used as an animal model in biomedical research related to atherosclerosis. However, little is known about genetic variation in the low density lipoprotein receptor (LDLR) gene, its effect on cholesterol levels, and associated risks of atherosclerosis. There-fore this study aimed to identify genetic polymorphisms, namely single nucleotide polymorphisms (SNPs), within the promoter region of LDLR and their relationship with animal responsiveness to hypercholesterolemia due to an atherogenic diet. In this research, SNPs were studied using DNA isolated from22 cynomolgus monkeys obtained from aprevious study, consisting of two hyporesponders, 19 hyperresponders, and one extremecase. The result showed that two SNPs existed in the promoter region, namelyg.−169T>C and g.−265G>A. SNP g.−265G>A showed linkages with extreme responsiveness and can be used as a potential genetic marker for extreme animals. The result of this study has extended our knowledge of polymorphism in the LDLR geneand its use intheselection of cynomolgus monkeys as animal models in research on hypercholesterolemia and atherosclerosis.

Abstract

The objective of this research was to examine the correlation between estrogen level and estrous cycle of rat fed with soybean flour and tempeh flour. A completely randomized design was applied in this study with 6 treatment groups and 5 replications. Rats in group 1, 2, and 3 were non-ovariectomized rats which were fed with pellet, 10 g soybean flour/100 g body weight/day, and 10 g tempeh flour/ 100 g body weight/day, respectively. The rats in group 4, 5, qnd 6 were ovariectomized rat which were fed with pellet, 10 g soybean flour/100 g body weight/day, and 10 g tempeh flour/100 g body weight/day, respectively. The rats were after fed with pellet, soybean and tempeh flour for 4 weeks, the estrous cycle phases of rats were examined based on the presence of vaginal epithelial cells and the number of qualitative vaginal epithelial cells, while the estrogen concentrations in serum were measured by radioimmunoassay method. The data was analyzed using analysis of variance and followed by Duncan multiple range test at 95% confidence. Non-ovariectomized rats given tempeh flour have longer estrus cycle than the non-ovariectomized rats which given soybean flour. The isoflavon contained in tempeh flour and soybean flour induced proliferation and cornification of vaginal epithelial cell. Feeding the soybean flour and tempeh flour to ovariectomized rats could optimize the estrogen hormone in initiating the estrus phase, in which of the tempeh flour addition had better effect than soybean flour. Correlation between the level of estrogen to the length of estrous cycle in both nonovariectomized rats and ovariectomized rats was positive, in which the higher the levels of estrogen the longer the length of estrous cycle.

Abstract

The study aimed to identify genetic variation of cDNA sequence from low density lipoprotein receptor (LDLR) gene of hyporesponder cynomolgus macaques. The animal used in this study was one hyporesponder cynomolgus macaque obtained from selection result in Primate Research Center-Bogor Institute of Agriculture (PSSP IPB). Amplification of cDNA from LDLR gene was performed using polymerase chain reaction (PCR) method with 4 pairs of walking primer. Alignment of amplification result sequence from 4 pairs of walking primer generated target sequence of 2353 bp which located on position 188-2540. Analysis of target sequence alignment on reference sequence in GenBank found 8 single nucleotide polymorphism (SNP), namely c408CT; c.1200CT; c.1497CT; c.1644TC; 1791TC; 1804AG; 2088CT; and 2377GA. Of 8 SNPs, c.1804AG and 2377GA. Two SNP (c.1804AG; dan 2377GA) caused changing of amino acids composition namely p.K602E (lysine → glutamate) and p.V793I (valine → isoleucine). This result proved the potential use of genetic variation of cDNA sequence from LDLR gene as genetic marker for selection of hyporesponder cynomolgus macaques.

Abstract

The assessment of the morphology and stingray species distribution of the Himantura uarnak species complex covers eight sampling sites in western and eastern Indonesia as many as 113 individuals. The observation of the reticulate pattern was accomplished by directly checking the dorsal side of the stingrays, and growth observations also carried out. The distribution patterns were analyzed using the principal component analysis (PCA), while the growth patterns were evaluated using correlation analyses. The reticulation patterns of the H. uarnak species complex were highly variable, and the distribution patterns based on the morphological parameters, species, and sex produced four groups. The distribution of the length frequency of H. undulata and H. uarnak showed a range of different sizes. The body length of the female in the western region is relatively longer than the male, while in the eastern region the female revealed a range in relative size showing that the male was longer than the female. The length-weight relationships of the stingrays were negative allometric, indicating a b-value of less than 3. The b-values of both the male and female H. undulata were 1.5860 and 0.4380, respectively; while the male and female H. uarnak were 0.2956 and 0.4376, respectively.

Abstract

The Mx gene is an antiviral gene used to determine the resistance or the susceptibility to different types of viruses, including the Avian Influenza (AI) virus subtype H5N1. The AI virus subtype H5N1 infection in chickens causes Mx gene polymorphism. The Mx+ gene shows resistant to the AI virus subtype H5N1, whereas the Mxgene shows signs of susceptible. The objective of this research was to detect the Mx gene in wild aquatic birds using the Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method with the primer pairs F2 and NE-R2/R and the RsaI restriction enzyme. DNA samples were obtained from eight species of wild waterbirds with positive and negative exposure to the AI virus subtype H5N1. DNA amplification results showed that the Mx gene in wild aquatic birds is found in a 100 bp fragment, which is the same as the Mx gene found in chickens. However, unlike chickens, the Mx gene in wild aquatic birds did not show any polymorphism. This study proves that Mx- based resistance to AI virus subtype H5N1 in different in wild birds than in chickens.
