Detection of Potyvirus using Reverse Transcription-Polymerase Chain Reaction (RT-PCR) and Antigen Coated Plate-Enzyme Linked Immunoabsorbent Assay (ACP-ELISA) for Dioscorea alata, D. hispida and D. 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. Â Â Keywords: Dioscorea spp., Potyvirus, RT-PCR, ACP-ELISA, in vitro shoot multiplication

Dandelion (Taraxacum officinale Weber ex F.H. Wigg) is a medicinal plant species, reported to have some active compounds useful as anti-cancer, anti-inflammatory, antioxidants, and diuretics. Study on in vitro secondary metabolic production and tissue culture of these plants has been reported. This research was aimed to investigate plant regeneration from leaf blade, petiole and root as explants grown in selected media. Three different type of explants were cultured in MS solid medium supplemented with BAP (0, 0.5, and 1.0 mg/l) combined with NAA (0, 0.5, 1.0, and 2.0 mg/l) to select the best medium for spontaneous regeneration. Explants were grown for 6 weeks, the viability of explants, and formation of callus, shoots as well as roots were recorded. The results showed BAP at 1 mg/l combined with at 0.5 mg/l of NAA was suitable for shoot formation, whereas NAA alone was suitable for root formation from leaf blade and petiole. Root was the best explant for shoot regeneration, callus was grown at the first two weeks, and multiple shoots were grown after 3 weeks. No roots were found from root explant. The best medium for multiple shoot regeneration was MS containing 1 mg/l BAP without or with addition of 0.5 mg/l NAA.Keywords: Taraxacum officinale Weber ex F.H. Wigg, growth response, plant growth regulators, different explants, regeneration

Tacca leontopetaloides (L.) Kuntze which belongs to family Taccaceae is one of tuberous plant useful as an alternative food. This plant contains starch (amylose and amylopectin) similar to that of potato. In addition, this plant also contains secondary metabolites potential for diarrhea, dysentery, and anticancer. In Indonesia, this plant grows at coastal areas i.e. in Sukabumi, Yogyakarta, Garut and Karimunjawa, so this plant was suspected to have high tolerance on salinity stress. The purpose of this research was to investigate the effect of increase in NaCl concentrations on growth and its proline content of T. leontopetaloides grown in vitro. In vitro shoot tips were cultured on MS medium (Murashige & Skoog, 1962) supplemented with NaCl at concentrations of 10; 25; 50; 75; 100; 150 and 200 mM, respectively. After six weeks in culture, shoots height, shoots number, leaves number, fresh weight, as well as their proline content were recorded. The results showed that fresh weight of shoots grown on MS medium supplemented with NaCl from 10 to 100 mM was hogher compared to those of the control treatment. Fresh weight decreased when shoots were cultured on MS medium supplemented with NaCl at more than 100 mM. Height of shoots, number of shoots, and number of leaves decreased along with the increase of NaCl concentrations. The best medium for growth was MS medium supplemented with 25 mM NaCl. In this medium proline content was 15.7 umol/g FW. Proline concentrations increased along with the increase of NaCl concentrations. LD50 value was 146 mM NaCl. In conclusion that on MS medium without addition of plant growth regulators, T. leontopetaloides shoot culture was sensitve to the increase of NaCl concentration.

Publisher : Research Center for Biotechnology - Indonesian Institute of Sciences (LIPI)

Jatropha curcas L. is a potential source of a non-edible biofuel. Conventional propagation of J. curcas technique has some limitations. Somatic embryo can produce a large number of embryos and obtain a large number of plants all year round. Treatment of sucrose in combination with polyethylene glycol (PEG) was proven to enhance germination of somatic embryos in many plant species. The aim of the study was to investigate the effect of sucrose in combination of PEG on somatic embryo germination in J. curcas. Globular somatic embryos at 0.025-0.030 g fresh weight having 0.4-0.5 cm in diameter were grown on MS medium solidified with 3 g/l of Gelzan supplemented with sucrose at 20, 30, 40, and 50 g/l in combination with PEG at 0, 2.5, 5, 10, and 15%. Results showed that the best medium for germination of J. curcas somatic embryo cultures was MS medium supplemented with 20 and 30 g/l of sucrose in combination with 5% of PEG. The numbers of germinated embryos per clump had significant enhancement on those medium compared with the control (PEG free treatment) (2.65 to 5.65) and (2.55 to 5.50). In addition, those treatments resulted in the highest percentage of clumps forming germinated embryos (100%), with an average of normal germinated embryos at 94.163 and 96.065%. The addition of 40 and 50 g/l of sucrose in combination with 15% of PEG caused all embryos to fail at germinating.

Artemisia cina is a medicinal plant species producing bioactive compounds which are potential as antitumor, antifungal and antibacterial. The aim of this study was to analyze the stabililY of chromosome number in root cultures of A. cina. Transformed root culture was established by infection of leaves of A. cina with Agrobacterium rhizogenes strains 07-20001 . ATCC-15834. A4 and A. tumefaciens strain RlOOO . Roots isolated from glasshouse plants, plantlets grown in solid and liquid MS medium were utilized for investigation of chromosome examination of untransformed roots. Chromosome examination was conducted by squashing method and chromosome numbers were calculated under microscope. The .results showed that both untransformed and transforme root had instability in the chromosome number, but had the modal number of chromosome x=8 with the diploid number of 2n = 4x = 32. Roots isolated from glasshouse plants of A. Cina had 53.7% of cell with the diploid numbers of 2n = 32 and 46.3% of cells had chromosome numbers ranged from 2n = 12 to 2n = 64. Untransformed roots isolated from plantlets cultured in solid medw had only 36.1 % or cells with chromo orne number of 2n = 32, and unlran fomled ro t5 grown in liquid medium had 49.4% of cells with 2n = 32. The chromosome numbers of A. Cina transformed roots was affected by trains of Agrobacterium. Root transformed with the bacterium Strain 07 -20001 showed lhe highest in normal chromosome number of 2n = 32 (62.4%) followed by roots lransformed wiLll strains ATCC-15834 (61.9 %). R1000 (43.6%) and A4 (43.0%). The range of the chromosome number untransformed roots was from 2n= 17 to 2n=64 whilst that of transformed roots was from 2n= 1 l to 20=66

The aim of this research was to compare the reduction effect of sucrose or table sugar concentration on growth characteristics of red ginger cultured in MS liquid medium. Shoots of red ginger was cultured on MS liquid medium without addition of plant growth regulators, supplemented with 5, 10, and 20 g/l of sucrose or table sugar for 8 weeks. Resulted plantlets were acclimatized in a greenhouse to investigate their growth and survival rate. Numbers of stomata, chlorophyll concentration as well as cross section of leaves from plantlets grown in vitro were compared to those of transplants grown in the greenhouse. The results showed that the use of table sugar at concentration of 20 g/l gave the best growth of red ginger. Meanwhile, the reduction of table sugar from 20 to 10 g/l reduced growth and survival rate of in vitro shoots as well as that of transplants in the greenhouse. Only few shoots formed roots when they were grown on the medium containing 5 g/l of table sugar, and transplants failed to grow in the greenhouse. It found that the chlorophyll content of in vitro plantlets was lower than those of transplants grown in the glasshouse. However, the number of stomata of the in vitro plantlets was higher than that of transplants grown in the glasshouse. There was no anatomical abnormalities found on the cross section of leaves between in vitro plantlets and transplants grown in the greenhouse. The replacement of sucrose with table sugar may reduce the production cost of plantlets.Keywords: red ginger (Zingiber officinale Rocs.), reduction of sugar, survival rate, chlorophyll, stomata.

Exploitation on plant population may put the endemic plants into an endangered state, hence, these plants will need to be conserved. In order to pursue conservation on endemic plants, we conducted in vitro seed germination and shoot multiplication of seven alpine and sub-alpine species endemic to Mount (Mt.) Jaya, in Papua, Indonesia, i.e. Tetramolopium klossii, Deschampsia klossii, Papuacalia cartenszensis, Epilobium hooglandii, Gaultheria novoguinensis, Rhododendron correoides and Rhododendron culminicolum. These species are categorized as slow-growth plants found in higher altitude (over 3700 m above sea level) and low temperature of Mt. Jaya. Seeds were surface-sterilized using Na-hypochloride and germinated aseptically on Murashige and Skoog (MS) medium. Dytikinin benzyl adenine (BA) was used for shoot multiplication. Seedling cultures were maintained in a controlled environment withÂ continuous low light intensity (800 lux) and at temperature 26-27oC. Results showed that most species had more than 80% of germination rate on MS medium after a week in culture. BA was required to enhance shoots multiplication. Woody Plant (WP) (Lloyd & McCown, 1981) medium gave better shoot multiplication for R. culminicolum.

The protocol of micropropagation of Tetramolopium klossii (Moore) Mattfeld through adventitious shoot proliferation was established. This is the first report of T. klossii tissue culture. Seeds were surface-sterilized by dipping them in 10% of ethanol for 1 min followed by soaking in 1% of sodium hypochlorite for 10 min. The sterile seeds were germinated on MS medium solidified with 8 g/l of agar, supplemented with 20 g/l of sucrose. Two-month old seedlings formed some shoot clumps on MS solid medium without addition of any plant growth regulators. Small clumps containing 4-6 adventitious shoots were used for shoot proliferation on MS solid medium containing 0; 0.1; 0.5; 1.0 and 2.0 mg/L of BAP (benzylaminopurine) or kinetin. The results showed that medium MS without cytokinins (control treatment), and the addition of 0.1 or 0.5 mg/L of BAP was more effective for shoot proliferation compared to the medium with addition of BAP at higher concentration and the addition of kinetin. In further subcultures, multiple shoots grown on MS medium without cytokinins was Â more vigorous Â than that of shoots grown on other media, so that the shoots were ready for rooting. Medium containing 0.5 mg/L of BAP was the best for maintaining multiple shoot formation. Shoots formed roots on MS medium containing half strength of macro nutrients.

Tuber of purple yam (Dioscorea alata L.) has been used as an alternative food in some areas in Indonesia. The tuber contains high carbohydrate, has low glycemic index and is gluten free. Therefore, study on genetic improvement of this species needs to be carried out in order to increase its 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. An increase in NaCl level 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.Â Keywords: purple yam, Discorea alata L., NaCl, in vitro growth, proline content.
