Abstract

The conventional propagation of physic nut (Jatropha curcas) is difficult, because it requires a high number of mother plant, which is very limited. In vitro culture is an alternative technique to conventional one to solve the problem.  An experiment was done to obtain the best in vitro culture media for shoot induction and multiplication. This research was separated into two steps, (1) in vitro induction of explant growth, and (2) in vitro shoot multiplication.  Results showed that medium of WPM + 2.0 ppm BAP induced shoot and leaf better than the control.  The highest number of leaf axillary's multiplication was obtained from the medium WPM + 2.0 ppm BAP + 0.1 ppm NAA. Various medium formulations for the induction and multiplication of shoots resulted in highly leaf fall.  The use of DKW + 2.0 ppm BAP + 0.4 ppm TDZ + 3.0 ppm AgNO3 medium has effectively induced shoot multiplication and reduction of dehydrated leaf. Meanwhile, the used of DKW medium supplemented with 5 ppm kinetin resulted in the best shoot elongation.   Key words :  Induction, in vitro, Jatropha curcas, shoot, multiplication

Abstract

Keladi tikus merupakan tanaman obat yang bermanfaat sebagai obat kanker. Keladi tikus memiliki kandungan kimia diantaranya adalah alkaloid, flavonoid, saponin, steroid dan glikosida. Keladi tikus memiliki keragaman genetik yang rendah. Untuk meningkatkan keragaman telah dilakukan mutasi secara fisik melalui iradiasi sinar gamma pada kultur in vitro keladi tikus. Media MS dengan penambahan 0.5 mg/l 2.4D dan 0.1 mg/l kinetin menghasilkan jumlah tunas terbanyak yaitu 14.38 plantlet. Kalus embriogenik mutan dihasilkan melalui induksi dengan sinar gamma 6 gray. Kalus embriogenik diregenerasikan menjadi 59 tunas mutan. Plantlet mutan yang dihasilkan telah dideteksi dengan marka molekuler RAPD dan menunjukan perubahan genetik. Beberapa galur mutan yang telah diperoleh memiliki keragaman tinggi secara morfologi dan genetik. Keragaman genetik klon mutan generasi pertama (MV1) sampai generasi keempat (MV4) yang diperoleh telah dideteksi secara genetik molekuler dengan RAPD. Beberapa klon MV5 (mutan stabil) memiliki kandungan senyawa bioaktif antikanker tinggi berdasarkan GC-MS. Analisis GC-MS menunjukkan bahwa tanaman mutan mengalami peningkatan kandungan senyawa antikanker dibanding kontrol serta senyawa baru yang tidak ditemukan di kontrol. Beberapa klon unggul yang dihasilkan perlu dikembangkan sebagai bahan baku obat antikanker. Keladi tikus unggul bermanfaat untuk mencegah dan mengobati penyakit kanker pada masyarakat Indonesia.

Abstract

Increased production of sugarcane in Indonesia can be done with extensification sugarcane plantations which largely dominated by acidic upland red-yellow podzolic soil. High aluminium (Al) content and low pH of the soil can inhibit plant growth and development. Tolerant sugarcane in acid soil is the most efficient way, but the adaptive variety is still limited. In vitro culture technique can increase genetic variability to assemble new varieties through somaclonal variation combined with mutation using ethyl methane sulphonate (EMS). The new characters was directed by in vitro selection using AlCl3.6H2O with pH = 4 as a component of selection for resistance to high aluminium. VMC 7616 and PS 862 varieties were used as materials. Mutation induced using EMS at concentrations of 0.1%, 0.3%, and 0.5% for 30, 60 and 120 minutes. Plantlets mutant obtained through callus formation, immersion callus in EMS, in vitro selection, and regeneration of callus. Result of study showed that the long immersion in the EMS solution caused greater damage to the cells, as indicated by the change in callus colour. Callus immersion time in EMS gave greater influence to regeneration compared to concentration of EMS. PS 862 had higher Al tolerance than VMC 7616. Rooting of shoot induced using indole-3-butyric acid (IBA) 3 mg/L.

Abstract

Rodent tuber (Typhonium flagelliforme Lodd.) is a herbal plant from the Araceae family. The plant has high medical potential and is effective to cure cancer. However, the low level of its genetic variation limits its exploration for desirable traits. The low level of genetic variation in Rodent tuber is mainly due to its asexual reproduction system. It usually reproduces vegetatively via tuber separation. Therefore, gamma irradiation had been applied to rodent tuber in vitro to increase its genetic diversity. The objective of this study was to analyze the genetic diversity of the first generation (MV1) of gamma irradiated rodent tuber mutant using random amplified polymorphic DNA (RAPD) markers. A total of 14 mutant DNA samples were analyzed with 14 RAPD primers. The result showed that 67 out of 123 DNA bands were polymorphic among mutant lines. Based on cluster analysis these mutants showed 0.78-0.97 genetic similarity. Cutting of dendogram at genetic distance of 0.89 produced four main clusters. Mutants with high genetic variation are now available. This increases the opportunity of obtaining mutant lines with high anti-cancer activity.

Abstract

Serangan penyakit malaria di Indonesia terus meningkat. Di lain pihak, penyebab penyakit ini yaitu Plasmodium falciparum telah resisten terhadap obat malaria yang selama ini digunakan. Artemisinin, dari tanaman artemisia telah diteliti dapat mengendalikan malaria. Permasalahan yang dihadapi adalah kandungan artemisinin dari Artemisia annua yang ditanamdi Indonesia masih sangat rendah, yaitu berkisar 0.1 — 0.5 %. Peningkatan keragaman genetik artemisia dengan menggunakan iradiasi sinar gamma merupakan metode alternative untukmengatasi masalah tersebut. Pada penelitian sebelumnya telah dilakukan induksi mutasi pada biji artemisia dengan dosis 10-100 Gy. Planlet hasil iradiasi yang mempunyai perakaran yang baik, diaklimatisasi di rumah kaca dan galur mutan yang didapatkan ditanam di Kebun Percobaan Gunung Putri, Balittro dengan ketinggian 1545 m dpl. Sebagai pembanding digunakan tanaman yang berasal dari biji (kontrol biji) dan tanaman dari kultur in vitro yang tidak diradiasi (kontrol in vitro). Hasil penelitian menunjukkan bahwa galur-galur mutan nmemperlihatkan keragaman morfologi, antara lain tinggi tanaman, bentuk daun, umur berbunga. Galur mutan umumnya berbunga lebih lambat dibandingkan tanaman kontrol. Sepuluh galur mutan telah terseleksi berdasarkan bobot basah dan bobot kering tanaman yang kemudian di analisis kandungan artemisininnya. Hasil penelitian menunjukkan kandungan artemisinin dari galur mutan bervariasi antara 0.44 — 1.41%, sedangkan kandungan artemisinin dari tanaman kontrol in vitro adalah 0.43%.

Abstract

INDUCTION MUTATION AND SELECTION OF IN VITRO PLANT OF WHEAT (Triticum aestivum L.)The goal of this research was to produce wheat crop which is tolerant to lowland condition.Six varieties were used, Dewata, Selayar, Alibey, Oasis, Rabe and HP1744. This research consisted of 4 stages: production of the best callus on MS medium containing 3 g/L 2.4-D, induced mutation of embryogenic callus using EMS, in vitro selection of callus at temperature of 27–35°C, and callus regeneration. The best result for callus production was 76% for Dewata and 70% for Selayar varieties. Higher concentration of EMS and longer soaking time decreased the percentage of callus growth. LC50 for Dewata was 0.3% EMS at 30 minutes and that for Selayar was 0.1% EMS at 60 minutes. The higher the temperature was, the lower was the adaptation tolerant of the plants, and callus growth was inhibited. At the highest temperature (35°C) the callus did not grow at all.Keywords: Induced mutation, Triticum aestivum, EMS, in vitro selection, callusABSTRAKTujuan penelitian ini adalah untuk merakit tanaman gandum yang toleran pada dataran rendah.

Abstract

Malaria is a global health problem that threatens 300-500 million people and kills more than one million people annually.Artemisinin, a sesquiterpen secondary plant metabolite extracted from Artemisia annua L., is a promising and potent antimalarial drug which has a remarkable activity against chloroquine resistant to Plasmodium falciparum. To counter the present low content(0.01-0.5%) of artemisinin in A. annua L.is a limitation to commercial production of the drug and uneconomical chemical synthesis. A research was conducted to induce callus production by using Murashige-Skoog (MS) medium added with NAA (0, 0.5 and 1 mg/1) and BAP (0, 0.5 dan 1 mg/1) and also to produce artemisinin from the calli. Complete Randomized Design was used in the research. Callus cultures were induced from leaf explants of A. annua. The research reports succesful approach for production of artemisinin by callus cultures of A. Annua. Medium formulation of MS basal media added with plant growth regulators BAP 0.5 mg/1 and NAA 0.5 mg/1 give the best result for callus induction than others, with callus fresh weight 844,4 mg, artemisinin content 0.73%, dry weight 216.6 mg and total weight of artemisinin 1.58 mg.

Abstract

Pineapple (Ananas comosus L. Merr.), represents an important crop in Subang. Somaclonal variation is one of the problem to develop pineapple, especially Simadu variety. Probability to conduct Simadu progeny from the mother plant is very low (5%).Its caused by chimeric of the somatic cells that form meristem.In vitro culture is the alternative method to solve the problem by using the meristem cells from Simadu fruit as explant. Unfortunately, genetic diversity has been observed in many spesies during tissue culture.This phenomenon is usually termed somaclonal variation. Many studies on pineapple demonstrsted that some in vitro propagated materials differ from the source materials from which they are derived.To minimize genetic variability, the use of growth inhibitor such as paclobutazol and absisic acid hopefully would gave the important role in genetic stability. The aim of the research is to multiply Simadu pineapple by using tissue culture technic. In vitro shoot induce from crown of the Simadu fruit until get the sterile shoots. Combination of kinetin (0-5 ppm) with paclobutrazol ( 0-0.1 ppm) or ABA (0-1 ppm) was used in the multiplication stage. Result showed that there are no interaction between kinetin and paclobutrazol or ABA, but there is influence of the single factor. Kinetin increase leave number but decrease plant height and root number. Paclobutrazol increase shoot and leave number, but decrease plant height and root number. There is no influence of ABA to plant height, shoot and root number but decreased leaves number.

Abstract

Papaya is climacteric fruit. As the other climacteric fruit, papaya has hight speed ripening, so papaya fruit can not stored in long period. Genetic enginering is one alternative technology to solve the problem by introducing antisense oxidase ACC gen to the papaya plant genome to get delay ripening characteristic. Success of genetic enginering technology depend on plant regeneration system.There were two ways of plant regeneration: organogenesis and somatic embryogenesis. The aim of this experiment was to induce root formation of papaya planlet which trasformated by ACC oxidase antisense gene.The former experiment showed that explant which transformated by ACC oxidase antisense gene can regenerated to be shoot/planlet with P6 medium.But when the shoot transferred to root induction medium the root was difficult to formed, callus was formed at the base of shoot, the leaves turn to yellow and fall down.Many media formulations were tried in this experiment with different basic medium for root induction and development.MS (1, Vi) DKW (1, A) and WPM (1, Vi) were used as basic media combined with sucrose (2 % and 3 %) and plant growth regulators (kinetin, IAA, and paclobutrazol) adding with some organic compound. Result of the experiment showed that MS Vi + paclobutrazol 0.5 mg/1 induced root formation 80 %, inhibited callus formation and decreased yellowing and falling of the leaves.
