Abstract

This study conducted in Laboratory of Molecular Biology, Balai Besar Bioteknologi dan Sumberdaya Genetik Pertanian (BB- Biogen) Bogor. The aims of this study are to determine and comparing the quantity,  quality and the efficiency of DNA isolation result using detergent method and CTAB method.  The parameters observed in this study are the value of DNA concentration, purity, and visualization result using gel electrophoresis. The samples are the leaves of Salak ‘Pondoh’ (Salacca zalacca (Gaert.) Voss.). Detergent method is a method which was developed by Faculty of Biology UGM, it has simple method and relatively affordable cost. Meanwhile, CTAB method is one of the commonly used methods of DNA isolation protocol with relatively expensive cost.  Detergent method used detergent in the cell wall separation and protein removal in the sample. The CTAB method used Cetyltrimethyl ammonium bromide (CTAB) for cell membrane separation in the sample. The research methods included DNA isolation with detergent and CTAB methods, PCR analysis and electrophoresis. Data analysis was done quantitatively  using spectrophotometric method and qualitative used electrophoresis method. The result of the study  showed that DNA isolation using  CTAB method showed higher purity compared with detergent method with the purity values ranging from 1,3- 1,4 . Meanwhile, the concentration of DNA in the detergent method was higher than that of CTAB with the highest concentration of 1730 µg/ml. There is no difference between the  quality of genomic DNA isolated by CTAB and detergent methods.

Abstract

A total of 21 aquatic plant species were collected from Bantimurung waterfall areas, South Sulawesi, Indonesia, in October 2017. These plant materials were subjected to both species and phytochemicals identification. The aims of this study were to determine the species or taxonomic rank of Indonesian aquatic plants collected from Bantimurung waterfall, South Sulawesi, Indonesia and to identify their chemical compounds (phytochemicals) as a candidate for new herbal medicine. Plant genetic materials used in this study were collected from Bantimurung Bulusaraung waterfall and were then identified based on standard botanical techniques for species identification in the Herbarium Bogoriense, Research center for Biology Indonesian Institute of Science (LIPI), Cibinong, West Java. The samples were subjected to the phytochemistry screening such as alkaloids, flavonoids, tannins, saponins, glycosides, terpenoids and anthraquinone followed the procedures of Indonesian Materia Medika and Harborne.  Results showed that all collected aquatic plant samples were able to be identified, including their species names. Phytochemical screening of each sample revealed the presence of glycoside in all of the tested species. However, no alkaloids, anthraquinones, and terpenoids were observed in those tested plant samples. Of the total 21 aquatic plants, 14 species contained flavonoids, 8 species contained phenol compound, and 10 species contained saponins. Among these species Donnax canniformis possessed good antioxidant activity, which correlated to its total phenolic and flavonoid contents. Our results would be beneficial for any future effort in the development of new herbal drugs derived from aquatic plants.

Abstract

The escalating demand of shallot has forced the increase of domestic production, including through extension of harvest area by utilization of arable land on peatland. This study was aimed to analyze genetic profile of shallot adapted in peatland areas using SSR markers. Twenty-one shallot genotypes were tested in the field and eighteen primers dispersed throughout the genome was applied to analyze genetic diversity of the peatland-adapted shallots. Phenotypic evaluation revealed that shallot yield potential ranged from 6.66 to 14.21 t/ha. Of these, seven shallot clones (11 NA, 1111 TA, 12 NA, 12 NC, 20 NA and 22 N) had good yield potential and comparable with those of five released shallot varieties. Nine out of 12 shallot clones were moderately resistant to Alternaria porii. Clustering analysis showed that shallot genotypes were clustered into two main groups, Clustered I and II which consisted of 13 and 8 genotypes, respectively. The closest genetic relatedness was observed between 8NC and 8NA (0.85), while the farthest ones was between 11NA and Kramat2 (0.51). This result implies that cross combination between 11NA and Kramat2 is valuable and suitable for breeding programs aimed at improving shallot potential yield in the future.

Abstract

This study was aimed to identify the potential use of active compounds extracted from Staurogyne sp as an antibacterial agent to control disease-causing bacteria in fish. Staurogyne sp, an aquatic plant collected from Bantimurung, South Sulawesi were subjected to allelochemical compound. Plant extracts were tested to five bacteria including four types of bacterial pathogen, such as Aeromonas hydrophilla, Edwardsiella ictaluri, Streptococcus agalactiae, and Flavobacterium columnare, and one bacterial sensing quoroum, Chromobacterium violaceum. Based on phytochemical analysis, Staurogyne’s extracts derived from both stem and root contained flavonoids, phenols, and antioxidants compounds with the concentration of 0.018 mgQE/g, 0.3471 mgGAE/g, and  1004,391 IC50 µg/mL, respectively. In addition, Staurogyne plant extracts derived from both their stem and root has also produced both saponins and glycosides compounds. Plant extracts derived from Staurogyne’s leaves revealed three major chemical compounds such as flavonoids (0.77 mgQE/g), phenol (0.0629 mgGAE/g), and glycosides (+). However, no antioxidants and saponin compounds were detected.  Applying plant extracts as an antibacterial on five disease-causing bacteria causing diseases in aquaculture, such as Aeromonas Hydrophilla, Edwardsiella ictaluri, Streptococcus agalactiae, Flavobacterium columnare, and Chromobacterium violaceum bacterials revealed that at concentration of 0.1 g the Staurogyne sp extracts did not influence all the bacterials growth. However, by application of plant extract at concentration of 0.2 g on the growth media,three out of 5 tested bacterials (Aeromonas hydrophilla, Edwardsiella ictaluri, and Streptococcus agalactiae) showed intermediate inhibition responses on bacterial growth. The growth of remaining two bacterials pathogen, Flavobacterium columnare and Chromobacterium violaceum at 0.2 g plant extract of Staurogyne sp was not affected. This study revealed that the use of active compound derived from Staurogyne sp would be potential to be used in inhibiting disease-causing bacterial in fish in future. However, optimum concentration of the plant extracts, in particular on the inhibition of the growth of disease-causing bacteria in fish is still needed to adjust.Key words: Antibacterial, aquatic plant, Staurogyne sp, fish disease

Abstract

Aquatic plants are an indicator of the fertility of an aquatic region. The waters of Lake Tempe are the largest waters of the lake area in South Sulawesi. Lake Tempe is located in the western part of Wajo District, precisely in Tempe District, about 7 km from Sengkang City towards the banks of the Walanae River in southern Sulawesi. The area is about 13,000 ha with a maximum depth of 5.5 m and can reach more than 30,000 ha during floods, and during the dry season, the inundation area reaches only 1,000 ha with a maximum depth of 1 m, located above the continental and Australian and Asian plates. This lake is one of the tectonic lakes in Indonesia. Every year silting the lake occurs. The Tempe hydro vegetation and eco-physical research were carried out in October 2017. The purpose of this study was to record aquatic plant species that live in Tempe Lake and observe ecological changes and physical properties of Lake Tempe. Aquatic plants are expected to be able to filter lake water. The results obtained are physical conditions of sharp-smelling water, unpleasant taste, dark brown, and cloudy color. Chemical indicators of NH3-N waters (0.2976-0.0634), PO4-P (0.0172-0.0844) NO2-N (undetectable), NO3-N (1.7131-1.9335), Sulphate (27.761900 - 37.047620), DO (6.88-7.18) and pH (7.88-8.02). There are 14 species of aquatic plants found in these waters. The most dominant species is water hyacinth. In the case of Tempe lake water vegetation results in siltation of the lake area.Keywords: Aquatic plant, Biodiversity, Species, Tempe lake,

Abstract

Huanglongbing, inflicted by Candidatus Liberibacter asiaticus in Asia region, is a destructive disease affecting citrus productions worlwide. Several studies have identified resistance genes that play essential roles in the citrus defense system against this pathogen. The goals of this study were to design the specific gene primers from the WRKY70 gene sequence and analyze the nucleotide variations and genetic diversity among several citrus genotypes. Genomic DNA from nine citrus genotypes were amplified using WRKY70-specific gene primers and the products of PCR were sent to Sanger sequencing, while the sequences of the other 12 genotypes were collected from Citrus Genome Database. The results revealed a total of 282 nucleotide variations which consisted of 157 SNPs, 28 insertions, and 97 deletions, were identified in the WRKY70 gene fragment sequence. There were three notable SNPs detected, with only one SNP [C/T] in first intron area at the position of 524 bp downstream from START codon that showed its ability to distinguish between susceptible and tolerant/resistant citrus genotypes. The phylogenetic analysis also revealed the clearly separation among citrus genotypes in two main clusters. The discovery of this SNP is useful for designing a functional marker as a screening tool in citrus breeding program in the future.
