  • Plant Response to Environmental Gradient Mediated by Trait Through
           Ontogeny on Common Tree Species at Two Contrasting Habitats in Karst
           Forest of Southern Taiwan

    • Authors: Muhammad Abdullah, I Fang Sun
      Abstract: One of central goal in ecology is to understand how plants respond to environment and what kind of attributes that can be obtained with an easy way to interpret the complexity of nature, especially on vegetation response. Ecologists use functional traits to understand how plants respond to environmental changes.  Plant species may have experienced different environmental conditions during their ontogeny. Thus, they may show different patterns of ontogenetic trait variation (OTV) as their response to different environmental condition. In this study, the relationship between trait variation on different habitat and across ontogenetic stages both on community and population levels were investigated. Five selected leaves traits (leaf area, specific leaf area, leaf thickness, leaf dry matter content, and leaf succulence) were examined to look at plant response along soil water content and light gap interception gradient in Kenting forest dynamics plot (KFDP), Southern Taiwan.  Leaf area was the most varied trait across habitat and ontogeny. Leaf thickness reveals an opposite pattern compare to leaf area. Leaf dry matter content (LDMC) showed less variation either between or within species and across ontogeny. Shift of community responses on environmental gradient by trait through ontogeny showed that intraspecific variation is important to be considered in ecological study. The other important finding in this study was by only using mean species we can misleading in understanding of plant responses to the environmental gradient in order to their adaptation both across different habitat and ontogenetic stages.

  • Ethnobotanical Study of Medicinal Plants in Karangwangi, District of
           Cianjur, West Java

    • Authors: Desak Made Malini, Madihah Madihah, Joko Kusmoro, Fitri Kamilawati, Johan Iskandar
      Abstract: The knowledge and usage of plant as medicinal remedy by current generation are not as extensive as previous; therefore, many rural communities with restricted modern medical access still rely on traditional medicine. This paper provides significant ethnobotanical information on medicinal plants in Karangwangi Village of Cianjur District, West Java Indonesia. This study aimed to identify plants collected for medical purposes by the local people as well as to document the local names, uses, preparation, and location of these plants. Ethno botanical data was recorded by opting people participation and key informant approach involving semi-structured interviews, group discussions and filling of questionnaires. The results showed a total of 114 medicinal plants belonging to 50 families were identified. Zingiberaceae was the most-frequently cited (nine species), followed by Asteraceae, Euphorbiaceae, and Fabaceae (seven species each). The most-used plant parts were leaves (51.8%), followed by stems (22.9%) and the most common preparations were decoction, poultice and squeezed. Most of the plants were obtained from the house-yard and total of 30 medicinal uses were recorded. The ethnobotanical result documented in this study showed that this area is rich in medicinal plants and these plants are still commonly used for medicinal purposes among the people in their daily lives. Ethnobotanical heritage should be preserved, however, there is a gradual loss of traditional knowledge about these plants in new generation. Further, the findings can be used as baseline information for further scientific investigation for analyzing phytochemical, pharmaceutical and other biological activities for future drug discovery.

  • The Expression of mRNA LMP1 Epstein-Barr Virus from FFPE Tumour Biopsy : a
           Potential Biomarker of Nasopharyngeal Carcinoma Diagnosis

    • Authors: Daniel Joko Wahyono, Nur Signa Aini Gumilas, Hidayat Sulistyo
      Abstract: Nasopharyngeal carcinoma (NPC) is a multifactorial disease that is endemic geographically in the world. Indonesian population has a highly incidence rate that is 6.2/100,000people year. The pathogenesis of NPC is more directly reflected by carcinoma-specific viral transcriptional activity at the site of primary tumour. Epstein-Barr virus (EBV) infection in NPC is reflected by the expression of EBV latent and lytic gene. In fact, mRNA Latent Membrane Protein 1 (LMP1) EBV expression was an important latent infection biomarker. The aim of this study was to determine a potential use of relative expression of mRNA LMP1 EBV from formalin-fixed paraffin embedded (FFPE) tumour biopsy in NPC as a tumour biomarker. This reseach design was a cross sectional study. The samples were the archived specimens of FFPE tumour biopsy from NPC WHO-3 patient which were collected from untreated patients from 2014 in the Department of Pathology Anatomy, Prof. dr. Margono Soekarjo Hospital, Purwokerto. The expression of mRNA LMP1 EBV expression was determined by RT-PCR technique. The positivity of mRNA LMP1 EBV expression was 50.2%, indicating a moderate positivity. The result proved that the expression of mRNA LMP1 EBV from FFPE NPC WHO-3 tumour biopsy was a potential biomarker of NPC diagnosis. The molecular methods would improved the management of NPC, particularly in the histopatological diagnosis of  NPC.

  • Antioxidant Activity of Dominant Plants Species in Obat Pahit from Lingga
           Malay Ethnic in Riau Archipelago

    • Authors: Fitmawati Fitmawati, Nery Sofiyanti, Rodesia Mustika Roza, Isnaini Isnaini, Yulisa Resti Irawan, Dhaniel Ridho Winata, Awal Prichatin Kusumo Dewi
      Abstract: Obat Pahit is a potion that has been long commonly consumed by Lingga Malay society for generations as stamina keeper. The most dominant plants found in the packaging of the Obat Pahit were namely Bauhunia semibifida, Cnestis palala and Penawa Root (3 species). This research aimed to investigate and determine activity of antioxidant contents in Obat Pahit from five Traditional Medicine Practitioners (TMPs) in the district of Lingga. The tested samples were mashed then being soaked into 2 types of solvent: distilled water and methanol, containing HCl 1%. DPPH method was also used in this research. Quantitatively antioxidant activity test of Obat Pahit from the five TMPs by using methanol solvent had extremely highest activity compared to the distilled water solvent. The test, using TLC plate by spraying the extract from three dominant plants with 0.1 mM of DPPH solution, produced a pale-yellow spots at a wavelength of 366 nm. On the other hand, the test using HPLC at wavelengths of 230 nm and 280 nm showed the presence of two dominant secondary metabolites contents: flavonoid and phenolic. IC50 (ppm) of Bauhinia semibifida (6.6247), Penawa Root (5.0124) and Cnestis palala (5.9968) were much lower than IC50 of mangosteen’s rind (41.7675), vitamin C (6.6612) and Stimuno drug (8.333). This antioxidant analysis has not been reported previously. This proof contributed greatly to uncovering potentially native natural resources as an indigenous Indonesian drug which is expected to decrease dependence on imported drugs especially imunomodulator, antihypertensive, antidiabet etc. This research would be beneficial and excellent manifestation for the development of natural antioxidant-based medicines from traditional knowledge of Indonesia’s local ethnicities.

  • Resistance of Advanced Soybean Lines to Pod Borrer (Etiella zinckenella
           Treitschke)

    • Authors: Heru Kuswantoro, Wedanimbi Tengkano, Marida S. Y. I. Bayu
      Abstract: The increasing and stabilizing of soybean product in Indonesia face many limitations. One of the limiting factors is pod borrer (Etiella zinckenella Treitschke) infestation that is able to cause yield loss up to 80%. Objective of the research was to find out some advanced soybean lines that resistant to pod borrer. Design was randomized completely block with three replications.  Soybean lines were grown gradualy to ensure the simultanously flowering. The plants were caged at 35 days after planting (DAT) and infested with the imago of E. zinckenella at 56 DAT. Results showed that different soybean lines affected imago population, eggs population, larvae population, infected pods and infected seeds. Some genotypes were consistantly resistant to E. zinckenella. The resistance of those genotypes were non preference resistance based on eggs population, larvae population, infected pod and infected seeds. This study discovered nine soybean lines that resistant to E. zinckenella, so that it can be beneficial for improving soybean resistance to this pest through releasing as a new pod borer resistant variety after tested further in potential yield and genetic x environment interaction trials. In addition, there were three varieties and two germplasm accessions that can be used as gene sources for improving the resistance of the varieties. The three varieties are able to be cultivated directly in farmer field to decrease the E. zinckenella occurrence.

  • Characterization of The Interaction Between RIN13 (RPM1-Interacting13) and
           Sumo Proteins in Arabidopsis Thaliana

    • Authors: Venny Santosa, Mio Nagabuchi, Sachiko Okada, Katsunori Tanaka
      Abstract: Small Ubiquitin-related MOdifier (SUMO) proteins can be found in many organisms, including A. thaliana, which possesses 9 SUMO genes. SUMO binds to various target proteins in a reversible reaction called SUMOylation. SUMOylation participates in transcription, chromosome organization, proteins localizations and stress responses. Our study showed that RIN13 (RPM1-Interacting13/At2g20310) is a target of SUMOylation, which was initially found by interaction between this protein and AtSCE1a (E2). Recent report showed that overexpression of RIN13 enhanced the resistance to pathogen without inducing hypersensitive response. However, the molecular interaction between RIN13 and SUMO proteins and its significance have not been studied yet. Thus, our study aimed to characterize the interaction between RIN13 and SUMO proteins in A. thaliana. The result showed an isoform-specific SUMOylation between RIN13 and SUMO proteins. RIN13 is SUMOylated by SUMO1, 2, 3, and 5. Though expressed ubiquitously in A.thaliana, fluorescence microscopy showed that RIN13 localizes subcellularly in the nuclear body. Moreover, complete abolishment of SUMOylation with inactive E2 suggests the exclusion of RIN13 from nuclear body. These results showed that SUMOylation affected RIN13 localization, and indirectly influenced its interaction to other proteins and putative function. This paper presents evidence of RIN13 SUMOylation. Furthermore, RIN13 function in pathogenic resistance is shown to be supported by SUMOylation. Thus, this study enhanced the understanding of SUMO in plants and served as reference to molecular studies concerning post-translational modification of SUMO.

  • Characterization of Ethanolic Extract of Streptomyces sp. As a Pancreatic
           Lipase Inhibitors Produced by Endophytic Streptomyces sp. AEBg12

    • Authors: Lenni Fitri, Anja Meryandini, Dyah Iswantini, Yulin Lestari
      Abstract: Endophytic Streptomyces sp. AEBg12 isolated from Zingiber cassumunar (Bangle) is known to produce pancreatic lipase inhibitory compound. However, the characteristics of this active compound has not been reported yet. This study aimed to determine the characteristics of pancreatics inhibitory compound produced by Streptomyces sp. AEBg12 and to assess the role of endophytic actinobacteria in producing pancreatic lipase inhibitor using endophytic-free bangle tissue culture, wild bangle and compared with the activity of Streptomyces sp. AEBg12 endophytes. Supernatant of Streptomyces sp. AEBg12 was extracted using ethanol, ethyl acetate, and n-hexane solvents. Toxicity test was performed using larvae of shrimp Artemia salina. The results showed that the best solvent to obtain pancreatic lipase inhibitor compounds was ethanol. Phytochemical analysis showed that ethanolic extract of endophytic Streptomyces sp. AEBg12 contained flavonoids. IC50 value of ethanol extract was 180.83 µg/ml. The result of TLC showed that ethanolic extract of Streptomyces AEBg12 had a blue luminescence band indicated that there were either flavone, flavanones, flavonols or isoflavones. Inhibitory activity of Streptomyces sp. AEBg12 was higher than wild bangle and bangle tissue culture. The benefit of this study was to obtain new compound which might be used as an antiobesity drug through approach to the pancreatic lipase inhibitor.

  • Genetic Variation in Cytochrome b-Hinf1 and -Alu1 Gene Correlated to Body
           Size in Soang Gourami (Osphronemus goramy Lacepede, 1801) from Single
           Spawning

    • Authors: Agus Nuryanto, Nael Huda Qonita, Hendro Pramono, Kusbiyanto Kusbiyanto, Petrus Hary Tjahja Soedibja
      Abstract: Soang gourami fingerling shows variable body sizes eventhough resulted from single spawning. Differences in body sizes among individuals is assumed to be correlated to their genetic component which can be studied using cytochrome b gene PCR-RFLP marker. This study aimed to determine specific PCR-RFLP marker among different sizes of soang gourami collected from single spawning. Genomic DNA was isolated using Chelex method. Cytochrome b gene were amplified and digested using four restriction enzymes. Specific markers were analyzed descriptivelly based on DNA band pattern appear in agarose gel. Ther result showed that PCR-RFLP markers of Cytochrome b-HinfI of 315bp, and 210bp, and also Cytochrome b-AluI of 334bp and 189bp are specific markers for large individuals, whereas small individuals are characterized by having Cytochrome b- HinfI 366bp, and 159bp and Cytochrome b-AluI 525bp fragments. It is observed that genetic variation of Cytochrome b-HinfI and -AluI markers are possitively correlated to body size in soang gourami fingerling. Therefore, both cytochrome b-HinfI and -AluI gene can be reffered as specific markers to differentiate among different sizes of soang gourami strain fingerling from single spawning. This result proved that genetic divergences among individuals can be related with certain quantitative characters, such size related. Therefore our study can contribute on fisheries development, especially by providing new technique for fingerling selection to obtain high quality fingerling and also provide new insight the application of molecular technique in fisheries.

  • Identification of Soybean Genotypes for Pod Shattering Resistance
           Associated with Agronomical and Morphological Characters

    • Authors: Ayda Krisnawati, Mohamad Muchlish Adie
      Abstract: A yield loss caused by pod shattering is one of the obstacles to the improvement of soybean productivity in tropical areas. The aim of this study was to identify the resistance of soybean genotypes to pod shattering as affected by agronomical and morphological characters. The field study was conducted in Malang, Indonesia, using 150 soybean genotypes. Data were collected on agronomical traits, the percentage of pod shattering, and pod morphological traits. Screening for shattering resistance was done as per oven dry method. Percentage of pod shattering was ranged from 0 % up to 100 % shattering with a mean of 58.11 %. Pod shattering was found to be negatively correlated with a number of pod per plant, the thickness of the pod, and Y/Z (seed weight and pod weight ratio). The screening obtained 66 very highly susceptible genotypes, 19 susceptible genotypes, 19 moderate genotypes, 38 resistant genotypes, and 8 very resistant genotypes. Two of eight very resistant genotypes (G511H/Anj//Anj///Anj////Anj-6-11 and G511H/Anj//Anj///Anj////Anj-5-4) have high yield, medium maturity day and large seed size. Those lines could be used as gene donor for soybean varietal improvement for shattering resistance, and recommended to propose as new improved soybean varieties resistant to pod shattering in Indonesia.

      Abstract: Pak Choy or Bok Choy (Brassica rapa L. var. chinensis) is one of favorite Chinese leafy vegetable for various dishes in Indonesia. In this study, it was used as a plant model to identify the appropriate organic hydroponic nutrient solution for leafy vegetable seedling production. The seed was sown on rock wool slabs submerged with 200 ml of a nutrient solution containing biofertilizer of Beyonic StarTmik@Lob (0, 25, 50, 75, and 100%). commercial hydroponic solution (0, 25, 50, 75, and 100%) and its combination (25, 50, and 75%). The experiments were arranged in a CRD. Meanwhile, the obtained data was analyzed using ANOVA followed by DMRT. The relationship among growth parameters was observed using Pearson correlation analysis.  The result of the study showed that the combination of organic and inorganic nutrient (25% Beyonic StarTmik@Lob and 75% commercial hydroponic solution) resulted in the highest seedling growth parameters and leaf indices as well as the perfectly positive correlations among growth parameters. This result indicated that the use of organic nutrient alone was not appropriate for hydroponic seedling production of Pak Choy. Therefore, further study needs to be done to identify the hydroponic solution without inorganic nutrients towards the organic vegetable production.

    • Authors: Tri Dewi Kusumaningrum Pribadi, Dzikrina Syahidah, Sairandri Dyah Harjanti, Desak Made Malini
      Abstract: One of the main problems in the waste management in Indonesia is the treatment of leachate. This research is aimed to obtain information of histological alteration in gills and liver of C. carpio L. exposed to leachate. Measurements on the water quality parameters comprised water temperature, pH, and dissolved oxygen (DO). This research was conducted by exposing leachate to C. carpio for 96 hours. The concentration of leachate were 0 ppm, 80 ppm, and 100 ppm. Histological preparation were made on the gills and liver using 10% fixative Neutral Buffered Formalin and Ehrlich Hematoxylin-Eosin staining with qualitative observation descriptive analyses for discussion. The result showed that increasing water temperature is directly proportional to the leachate concentration in the aquaria, while the value of pH and DO inversely proportional to the leachate concentration. Damages on the gills with 80 ppm leachate concentrasion were identified as follows: fusion of secondary gill filaments and hyperplasia of epithelial cell, along with karyorrhexis and hydropic degeneration on the liver. Damages on the gills of fishes exposed to leachate with 100 ppm concentrasion were identified as follows: fusion of secondary gill filaments, hyperplasia of epithelial cell, congestion, and edema along with karyorrhexis, hydropic degeneration and melanomacrophage centre (MMC) found on the liver. The results of this study can be used as an overview of the impact of an environmental pollution by leachate as indicated from histological damage to the gills and liver of C. carpio. So it can be used as input material in better waste management by considering that carp was regional ecological and economic importance in Indonesian.

      Pages: 363 - 369
      Abstract: The entomopathogenic fungus, Metarhizium anisopliae (Metschnikoff) Sorokin (Ascomycota: Hypocreales)would effectively infect the target host on the appropriate medium water content. The aim of this study was to analyze the influence of water content of medium on the effectiveness of M. anisopliae fungus infection on O. rhinoceros larvae in the laboratory. Fifty healthy third instar larvae of O. rhinoceros were  obtained from field. The M. anisopliae obtained from Estate Crop Protection Board in Salatiga. The conidia density and viability of M. anisopliae were examined before used. The medium for maintaining the larva was the sawdust that had been sterilized. A total of 50 plastic cups were prepared to place 50 larvae (1 larva/cup). Each cup was filled with 100 g medium  of sawdust plus 2 g of M. anisopliae which was then stirred until mixed, with different water content: P1 (20%), P2 (40%), P3 (60%), P4 (80% ) and P5 (98%). The result indicated that  the water content of the medium affected the effectiveness of M. anisopliae fungus infection on O. rhinoceros larvae. The water content influenced the duration of larval mortality at each treatment. An important finding in this study is that controlling O. rhineceros larvae  with M. anisopliae can be done by manipulating the water content of medium. The benefit of this study may be used for the recommendation of O. rhinoceros pest control using M. anisopliae  with an effective water media content.
