Abstract

Study on cryopreservation of Indonesian local cultivars and improved  varieties of maize and soybean has never been done. This method may be used for long-term preservation of seeds of maize and soybean. In this study, the method was applied to maize and soybean, Arjuna and Wilis respectively, as a model for preserving germplasm of ortodox seeds. Whole seeds and excised embryos of both varieties were subjected to twomethods of cryopreservation, i.e., two-stage cooling and rapid freezing with or without 15% dimethyl sulfoxide (DMSO) as cryoprotectant solution prior to immersion in liquid nitrogen (-196oC). Results indicated that there was no significant difference between the use of DMSO for both species in terms of viability, although pretreatment in DMSO was slightly reducedthe percentage of viability of both species. Slow freezing to -30oC prior to immersion in the liquid nitrogen could give as high as 76.67% and 51.67% surviving whole seeds of maize and soybean, respectively. Preserving excised embryos of maize in the liquid nitrogen using either slow or rapid freezing significantly reduced the percentage of viability from 20-76.67% to 5-18.33% (four folds) depending on treatments applied. Results also showed that one day or 15 minutes of immersion of samples in the liquid nitrogen gave rise to similar values of viability of maize and soybean, i.e., 20-60% and 20-51.67%, respectively depending on  treatments applied. These results implied that for long-term storage of maize and soybean seeds as they could survive at the rate of 76.67% and 51.67% respectively, the seed can be treated by prefreezing to -30oCwithout the presence of DMSO prior to immersion in liquid nitrogen.

Abstract

4-coumarate:Coenzyme A ligase (4CL) plays an important role in lignin biosynthetic pathway thatcatalyzed the activation of coumaric acid, caffeic acid or ferulic acid to be a syringil monomer. Ligninbiosynthesis control through 4CL down regulating would support lower lignin wood production. Theobjective of this study was to clone conserved region cDNA of gene encoding 4CL. Gene fragment isolation wasconducted by means of reverse transcriptase polymerase chain reaction (RT-PCR) using degenerateheterologous primer. The RT-PCR products were purified, sequenced and analyzed to select the highlyhomologous fragment to 4CL. BLASTanalysis result showed that deduction of amino acid sequences from oneof two RT-PCR product nucleotide was highly homologous with the 4CL conserved region from Rubbus ideaus,Oryza sativa, Populus tomentosa, Populus balsamifera, Betulla platyphilla, Nicotiana tabacum, and Arabidopsisthaliana with identity ranging from 78-90%.Key words: 4-coumarate: Coenzyme A ligase, lignin, sengon

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

The purpose of this study was to identify the selection criteria to obtain a superior mutant derived from the wheat plants of such varieties as Dewata, Selayar and Alibey, adaptive in medium land. The analysis of agronomic growth characters showed a significantly effect on a growth percentage of the initial growth (8 mutants), flowering time (1 mutant), panicle stem length (15 mutants), number of panicles (7 mutants), the number of grains per panicle (8 mutants), grain weight observed (8 mutants), grain weight per genotype (6 mutants), leaf area (2 mutants) and leaf greenness (5 mutants). The effects on the characters of ripe time, harvest, panicle length and plant height were not significant. The mutants of Dewata, Selayar and Alibey could be selected based on the characters of panicle stem length, number of grains per panicle and grain weight per observation because these characters generated more mutants than the other characters. The correlation analysis between the characters of growth and yield components of wheat mutants showed that the number of grains per panicle was positively correlated with the grain weight observed, while the length of panicle stem was positively correlated with grain weight per genotype, number of panicles and leaf area. Hopefully some mutants produced could adapt to the tropical medium land, thus adding to the diversity of wheat germplasm in Indonesia, thereby reducing the import of wheat to Indonesia.How to CiteSari, L., Purwito, A., Sopandie, D., Purnamaningsih, R. & Sudarmonowati, E.

Abstract

Sandalwood (Santalum album), which belongs to Santalaceae family, is a commercially important tree in Indonesia due to its many application. However,its population has significantly depleted since the planting materials using conventional methods are difficult to be provided. This study was conducted to mass propagate sandalwood using in vitro methods through friable embryogenic callus (FEC). The somatic embryos were formed using leaves cultured in MS +0.5 mg/l +1 mg/l indole acetic acid (IAA), and MS +1 mg/l IAA + 0.2 mg/l kinetin as well as 0.5 MS+1 mg/l Gibberellic acid (GA3). Primary somatic embryos (PSE) and secondary somatic embryos (SSE) then formed friable embryogenic callus when they were repetitively transferred to MS +1.5 mg/l BAP + 1.2 mg/l kinetin every 3 weeks. The maturation and regeneration of FEC was best done in the MS +1.5 mg/l BAP + 1.2 mg/l kinetin for 4-8 weeks. The acclimatization of sandalwood plantlets can be best conducted in the medium containing soil, sand and compos in ratio of 1:1:1 with the companion plant Murraya paniculata, which gave the best percentage of survival rate and the lowest percentage of falling leaves.

Abstract

Gebang is an Indonesian local genotype which has been selected as superior genotype for low amylose  cassava. Prior to induction of new mutants of this genotype, series of research have been conducted to improve regeneration and acclimatization as well as shoot cuttings production of irradiated in vitro shoots. Four dosage treatments of gamma ray irradiation i.e. those of at 0; 0.2; 1.0; 1.5; 2.0 krad were applied to 32 in vitro shoots multiplied from apical shoots of plants in the field. The highest multiplication rate and acclimatized shoots were obtained from shoots irradiated with 0.2 krad multiplied on various level of BAP added on MS medium and resulted that MS supplemented with 1 mg/L BAP was the best medium. The phenotypic variation was observed in shoots irradiated with 1.0; 1.5 and 2.0 krad while the ones irradiated with 0.2 krad performed normal appearances. Subsequent production of propagated young stem cuttings called “ratooning system” decreased after the second cycle of propagation especially in the survival rate of the ones irradiated with 0.2 krad. The findings lead to the opportunity to produce cassava propagules derived from irradiated in vitro culture at a higher amount using Gebang genotype as a model.Keywords: cassava Gebang, irradiated shoot, young stem cutting/ratooning , acclimatization, in vitro.

Abstract

Cassava is an important carbohydrate source that provides food security and alternative renewable energy development. This plant is naturally drought tolerant, but there is a wide variation within cassava genotypes in their ability to maintain high yield and starch production under drought stress. It has been reported that cassava clones with leaf retention or stay green trait can produce more total fresh biomass and high root dry matter compared to drought susceptible cultivars. The genetic, biochemical and molecular bases of stay green trait need to be understood to develop drought resistant cassava cultivars since water stress limits yield and starch production. Differential Display (DD)RT-PCR is a powerful technique for analyzing differences in gene expression. The method is based on the detection of the differentially expressed cDNAs from two or more samples. The main objective of this study was to identify differentially expressed cDNA in cassava under drought stress by employing a cDNA-RAPD approach. In this study, we used cassava genotype Ubi Kuning which was considered the most responsive to water insufficiency (45 days without watering). Leaf samples were collected from water stressed and well-watered plants at day 45. Among 11 random primers, OPB03 and OPH17 have identified differentially expressed cDNA in Ubi Kuning. Further characterization of these PCR products of expressed cDNA under drought stress may open possibility the development of cassava with improved drought resistance through genetic engineering and/or marker assisted selection (MAS).
