Abstract

Garcinia, belongs to the genus Guttiferae, is a very prospective plant for development. Because of apomixis, however, this plant has a narrow genetic diversity. This study aims to determine the genetic diversity and relationships of Garcinia based on the content of bioactive compounds and its biological activities, using in silico approach. A total of 64 Garcinia species were analyzed by a multivariate method using the MVSP ver. 3.1 software. The results showed that based on these characters, Garcinia had a low (narrow) genetic diversity, with a Shannon index of 0.28. However, the xanthone, antifungal activity, and leaf organ are the three of Garcinia characters with a high (wide) genetic diversity. The PCA revealed that these characters are contributed positively to this genetic diversity. The UPGMA analysis also revealed that this germplasm is divide into six main clusters, where the fifth is the largest (53 species). The farthest relationship is shown by G. hanburyi and G. cylindrocarpa, as well as G. bancana and G. excavata, at a coefficient of 0.54. In this case, G. mangostana, the most popular species of Garcinia, has the closest relationship with G. wightii at a coefficient of 0.87, and fartest to G. cylindrocarpa. This information might be valuable in supporting the preservation and breeding programs of Garcinia in Indonesia, particularly for parental selection in the development of superior cultivars.

Abstract

Plant have been cultivated for a long time, they have been selected and bred by our ancestors for their nutritional qualities, flavor, productivity, storage ability and other valued traits. Crop Wild Relative (CWR) are often neglected because they have not been used for domestication. However, world population growth together with the potentially adverse impact of climate change on agricultural production, calls for greater action to ensure global food security.  Indonesian Botanic Garden already ratified Convention on Biodiversity (CBD). One of the programs is the Global Strategy for Plant Conservation (GSPC). The GSPC vision is to stop the plant diversity loss through five objectives and 16 targets for plant conservation to be achieved by 2020. The study was to identify the implementation of target 9 of GSPC by Indonesian Botanic Garden Network. The result showed that there are four reason Indonesian Botanic Garden has participated in target 9 of GSPC, We also provided success stories from other botanic garden to encourage Indonesian Botanic Garden to conserve more Indonesian Crop Wild Relatives (CWR) whilst facilitating their use in crop improvement.

Abstract

Drought stress is the major abiotic stress affecting plant growth and productivity. This review emphasizes the discussion of plant response mechanisms when experiencing drought stress. The plant develops the strategies under water deficit conditions in the form of drought escape, drought avoidance, drought tolerance, or a combination of those strategies. Drought stimulates a wide variety of plant adaptation by changes in morphological, physiological, biochemical, and molecular levels. This mechanism is organized by a complex signaling network system comprising of signal perception, signal transduction pathway, and the regulation of drought-responsive genes expression.

Abstract

Fusarium wilt disease caused by Fusarium oxysporum f. sp. cubense is the most dangerous disease in banana. Recently, development of new banana varieties has been the most effective ways to prevent this disease. To develop the resistant banana, Fusarium severity analysis is the important part in the process of Fusarium disease assessment to quantify the disease severity.. The objective of this study was to develop digital image analysis method for Fusarium severity analysis by using software ImageJ. Pisang Ambon and Pisang Cavendish were used as plant material due to its susceptibility of the disease. Fusarium severity analysis performed as follows (i) Photographing of Fusarium-infected rhizom (ii) Digital image analysis by using ImageJ of the taken image. The analysis result was percentage area of Fusarium-infected rhizom, represented by necrosis and discoloration. The percentage of rhizome infected by Fusarium- of Pisang Ambon#1 was 50.10%, while Pisang Ambon#2 was 22.23%. In addition, the percentage of Pisang Cavendish#1 and Pisang Cavendish#2 was 28.52% and 39.5%, respectively. Digital image analysis of the sample showed consistent result and more objective. Development of the digital image analysis is not only useful for Fusarium severity analysis in Banana, but also for other crops.

Abstract

Chromium contamination can affect morphological, physiological, and anatomical changes, especially in chili vegetative organs. This research aims to understand micro-anatomical structure of the vegetative organs of chili subjected to chromium stress. The aim of the research is to know whether there is a micro-anatomical character difference between contaminated and uncontaminated chromium. The experimental methods using a completely randomized design (CRD). The independent variable is five levels of chromium concentration, i.e., 0; 50; 100; 200; and 300 ppm. The method of preparing anatomical preparations of the stem using a non-embedding and embedding method. The parameters observed in root and stem are organ diameter, xylem, thick of epidermis, and cortex. In contrast, leaf organ parameter includes thick cuticle, epidermis, mesophyll, stomata size (length and width), and stomatal number. The research results showed that organ anatomical structure, i.e., root, stem, and leaf in chromium stress condition did not change. Chromium deposition causes a decrease in root diameter, xylem, thick cortex roots, stem diameter, xylem, the thickness of the epidermis and cortex, leaf epidermal thickness, mesophyll, size of stomata width and number. In contrast, the chromium stress causes an increase in the thickness of the root epidermis (43,18%), cuticle thickness (36,36%), and leaf stomata length (33,33%) of chili as chromium concentrations increase. The anatomical structure of chili leaves changes after being contaminated chromium stress.

Abstract

Coral reef is an ecosystem which provides suitable habitats for sgroups of biota that has important ecological and economic values which can be used as bio-indicators to assess the health of the environment. Research on megabenthic fauna in Kendari waters and its surroundings, Southeast Sulawesi was carried out at nine permanent stations in 2015 to 2018. The data was collected using the Benthos Belt Transect method that modified from the Belt Transect method on 8 types or groups of megabenthos in these waters. The purpose of this study was to determine the density fluctuation of megabenthic fauna over the years. The mean density of individuals found at each station during the study did not differ significantly. The Kruskal-Wallis test on density of megabenthic fauna during this period of times did not show a significant difference (H = 28.511 > df 7 = 14.067). Drupella spp. was the group species of megabenthic fauna with the highest density each year (1,079-1,738 ind/ha), while lobster was the group species of megabenthic fauna with the lowest density each year (0 - 39.7 ind/ha). The crown of thorns starfish Acanthaster planci had the highest fluctuation where density increased from 28.3 to 71.4 ind/ha.

Abstract

Diabetes mellitus type 2 is the most common type of diabetes. This study was conducted to determine the effect of Mesenchymal Stem Cell-Conditioned Medium (MSC-CM) in Homeostatic Model Assessment of β-cell function (HOMA-β) value, normal Langerhans cells, and Transcription Factor 7-Like 2 (TCF7L2) gene expression in type 2 diabetic rats model. As many as 27 male Sprague Dawley rats were divided into 3 study research groups: normal control (9 normal rats), diabetic control (9 type 2 diabetic rats, induced by 60 mg/kg BW Streptozotocin and 120 mg/kg BW Nicotinamide i.p.), and treatment (9 type 2 diabetic rats treatment with 0.1 ml/200g BW MSC-CM i.p.). On day 30 after therapy, the expression of TCF7L2 gene was performed with real time-quantitative PCR (RT-qPCR). The HOMA-β value were calculated based on Fasting Insulins (FINs) levels and Fasting Blood Glucose (FBG) levels data from other research team members. Based on results, MSC-CM increases the HOMA-β value and amount of normal Langerhans cells of treatment group that indicates amelioration effect of MSC-CM, but there was no significant difference in TCF7L2 gene expression level between diabetic control and treatment group.

Abstract

Birds play an essential role in ecosystems, especially in urban landscapes such as the Cibinong Science Center (CSC). As an urban landscape, CSC always experiences land cover changes due to the development of research infrastructure resulting in various human-made land cover types. This study aims to determine the diversity of birds in various types of land cover as a community response to CSC development dynamics. Bird data was collected using the point count method modified with a grid (plot) measuring 200mx200m with a radius of observation as far as 50m at 34 points. Landsat images were analyzed from 2006 to 2018 to see changes in land cover changes. The observations show that there are 35 species of birds. Among those, three birds are protected by Indonesian regulation. There are six type of land cover in CSC paddy fields, buildings, opened area, farm land, plantation, and water. CSC has total diversity S(mean) = 32 covering 65% of all recorded birds. At land cover level, building area show the highest diversity (Shannon=2.03) while paddy fields is the lowest (Shannon=1.45). Based on the Landsat imagery, there are several changes in vegetation and the addition of some buildings.
