Abstract

The use of botanical seeds of shallot as planting materials is more effective than bulbs. However, the characteristics of plants are not ‘true to type’. Bibliometric analysis can identify areas that have been under- explored. Research on biomolecule compounds and gene expression is needed to support biomarker-based detection technology to predict plant productivity early.  This research aims to study the expression of the AcFT1 gene to compare two shallot plantlets with different responses (non-multiplied and multiplied). The AcFT1 gene was identified by bibliometric analysis. GapC2 (group of housekeeping genes) was selected as an internal control gene. The primer designed result were: AcFT1-F: 5’GCGAGAAACCGTCTGCTATGA3’; AcFT1-R: 5’GCAACTGGA GACCCAAGGTT3’; GapC2-F: 5’GCTGCACAACCAACTGCTTA3’; GapC2-R:  5’CCAGTGCTGCTAGGAATGAT3’. The RNA from micro bulb of shallot was then extracted and converted into cDNA with RT-PCR process. Based on the best-optimized PCR annealing temperature (55.2oC), the GapC2 and AcFT1 genes were expressed at the same thickness for both phenotypes, indicating the same level of expression in both micro bulbs. Further, this showed that AcFT1 cannot be used for comparative multiplication studies, this gene is more related to the bulb formation rather than the multiplication process.

Abstract

Abstract. Tropical countries are the largest contributor to the incidence of Dengue Hemorrhagic Fever (DHF), but research on risk factors is still independent in various countries, it cannot be concluded holistically. Through the research design, a systematic review is able to summarize and answer the causes of DHF in this tropical country. This research method is a systematic review with guidelines following the 2009 PRISMA Checklist. In the initial search, 1,680 articles were found using the keyword “risk factors for Dengue Hemorrhagic Fever”, reduced to 274 article titles after adding the keyword “tropical country”. Furthermore, the relevant abstracts were filtered and found 37 selected article items. Through critical appraisal of the full text of the article, it was found that 17 articles met the selection criteria for further review in this study. The results showed that there were 5 major groups of risk factors that were widely studied, namely sociodemography, climatology, place of dwelling, environment, and behavior. The sociodemographic factor associated with the incidence of DHF in tropical countries is age. In terms of climatology, temperature and rainfall are important factors in the vector breeding process. Rural areas (rural areas) are the place of dwelling with the most cases of DHF found. The environmental aspect that has been widely studied is mosquito breeding. The most significant risk behavior factor in transmission was the behavior of hanging clothes. Of the 17 articles, it was found that 77.8% of the articles examined environmental variables. Abstrak.

Abstract

High demand on black rice Oryza sativa L. due to their high antioxydant content and better nutrition than the white rice. On the other hand this high price rice still less interest for the farmet to cultivate it. Therefore, improvement of plant characters was carried out through polyploid induction using the natural anti-mitotic compound bio-catharanthine. The purpose of this study was to test the effectiveness of bio-catharanthine in inducing polyploidy in Cemp ireng black rice. This study used a two-factor completely randomized design (CRD) method with three replications. The treatment factor of bio-catharanthine concentration was 1%, 1.5 %, 2 %, 2 %, 2.5 % and 3 % with the soaking time of 48 hours. The germination rate, ploidy level, stomatal size and density, and antioxidant were measuret to observed the characteristic of the mutan. The results showed that the treatments of 3 % bio-catharanthine enhanced the chromosome number of black rice Cempo ireng. Biocatharantine did not affected the germination rate through the treatments. Out mutants shows alternation on the stomatal size and density. The antioxidant of leaf sample did not changed after the treatment. Bio-catharanthine on high concentration migh be possible to be applied on polyploidy induction in black rice

Abstract

Detection of Potyvirus using Reverse Transcription-Polymerase Chain Reaction (RT-PCR) and Antigen Coated Plate-Enzyme Linked Immunoabsorbent Assay (ACP-ELISA) for Dioscorea alata, Dioscorea hispida, and Dioscorea esculenta was conducted in order to establish in vitro culture of virus-free of these species. Plants were collected from Yogyakarta, Lampung, Pasuruan, Jakarta and Bogor. Total RNA of plants grown in a greenhouse was then isolated according to Simple Direct Tube (SDT) method. Total RNA from symptomatic leaf of Yard Long Bean (Vigna unguiculata) infected with Bean Common Mosaic Potyvirus (BCMV) was used as the positive control treatment. RT-PCR assay with degenerate primers MJ1(F) and MJ2(R) was used to identify the Potyviruses infecting Dioscorea. ACP-ELISA with antibodies specific to group Potyvirus was carried out to detect Potyvirus from leaves samples. The Dioscorea virus-free species was then cultured on modified MS medium. Shoot tips or internodes were used as explants. The results showed that using both RT-PCR and ACP-ELISA, all species tested were free from virus. The growth response of explants on MS medium was varied depending on the plant species and the concentration of BAP.

Abstract

Tuber of purple yam (Dioscorea alata L.) has been used as an alternative food in some areas in Indonesia. The tuber contains high carbohydrate, low glycemic index and gluten free, therefore, study on genetic improvement of this species is needed to increase the productivity and to find out new cultivars which can be cultivated in marginal lands. This research was aimed to investigate the effect of NaCl concentration on growth and proline content of purple yam grown in vitro. Shoot tips were cultured on MS (Murashige and Skoog) medium supplemented with NaCl at concentrations of 25; 50; 100; 200 and 250 mM. After six weeks in culture, height of shoots, number of nodes, number of leaves, as well as proline content were recorded. The results showed that shoots grown on MS medium supplemented with NaCl at 25 and 50 mM had better growth compared to control. The best medium for its growth was MS containing 50 mM of NaCl. Increase in NaCl level’s resulted in decrease of growth. The LD50 value was obtained at 183 mM of NaCl. The Highest proline concentration was achieved by shoots grown on the medium supplemented with 100 mM of NaCl. This result indicated that purple yam was tolerant to the increase of NaCl concentration up to 100 mM, on MS medium without addition of plant growth regulators.

Abstract

Tetraploid citrus are important for interploidal hybridization to create triploid seedless citrus. Colchicine is the most commonly used as antimitotic agent to induce polyploid plants. Tetraploid induction by colchicine in Pummelo ‘Nambangan’ was conducted in vitro using different types of explants. The aim of this research was to induce tetraploid pummelo ‘Nambangan’ by colchicine treatment using germinated seed, shoot tip and cotyledonary node as explants. Tetraploid shoot induction was conducted by soaking germinated seeds, shoot tips and cotyledonary nodes in 0.1 % colchicine for 1, 3 and 5 hours. Regenerant shoots were grown on MS medium and their growth was observed after four weeks in culture. Ploidy level was determined using flow cytometry analysis. Stomata density, length and width of stomatal guard cell were also recorded. The results showed that shoot elongation was inhibited by colchicine treatment. Soaking of shoot tip explants in 0.1 % colchicine for 1 hour resulted in 66.66 % of putative tetraploid shoots. Compared to diploid shoots, tetraploids had lower stomata density but bigger in guard cell size.
