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

Cassava (Manihot esculenta Crantz.) is a carbohydrate sources containing a limited amount of micronutrients, but some genotypes contain β-carotene as the precursor of vitamin A in the storage roots and leaves. Improvement of β-caroteneand minerals such as Fe / Zn content of cassava’s nutrition is mostly through by biofortification program. The storage root of β-carotene recognized by a yellow or yellowish color while the apical shoots with red to purplish. β-carotenein carotenoid biosynthetic pathway is an expression of the phytoene synthase (PSY) gene. The MePSY2 gene, one of the three MePSY family is the key gene to characterize carotenoids related gene in cassava. In this study, sequencing of the two cassava fulllenght PSY genomic DNA was carried out in conserved areas in the PSY gene region (PSY1 and PSY2) from the DNA of the cassava leaves. Adira1, Carvita25 and Ubi Kuning are yellow root storage genotypes (K1, K2 and K3) while Adira4 and Menti are white root storage genotypes (P1 and P2). Carvita25 is induced somaclonal variant of the Adira4 genotype. Contiq and consensus of nucleotide base sequences from the five cassava genotypes and CM3306-4 cultivars (acc GU111715.1) as references were analysed using the lasergene DNASTAR sequence analysis program. The results of the alignment of the base sequence constituent of the MePSY2 gene showed that the PSY2 gene with amplified genome length was 2,380 base pairs (bp) consisting of 1,140 bp exon region and 1,240 bp intron region. In the conserved coding region, there was a difference of one nucleotide base, that is, base C in two white tuber cassava genotypes replaced with A in three yellow tuber cassava genotypes in the 1.485 base (C1.485A). The SNP converts the amino acid (aa) alanine (A) to aspartic acid (D) at the 191th (A191D). Single Nucleotide polymorphism in conserved coding region can be used further as carotenoid marker for plant breeding of yellow root cassava. Keywords: β carotene, PSY gene, polymorphic gene SNP, yellow root cassava.

Abstract

Ralstonia solanacearum is one of the most important pathogen that causes bacterial wilt disease in eggplant and inhibits eggplant production. Improvement of eggplant varieties resistant to bacterial wilt can be accomplished through genetic manipulation. Regeneration of in vitro plants isone of the important tools to supports plant improvementthrough biotechnology. This study was aimed to determine the rate of eggplant regeneration in various maturation media, and to find the best medium for eggplant regeneration based on maturation rate and the number of cotyledon produced. We used resistant eggplant (accession 032) as the material to produce somatic embryogenic.There were 7 types of regeneration media used in this research. MS medium was supplemented with a certain concentration of plant growt regulators , such as: 1 mg / L + BAP 1 mg / L, NAA 4mg / L, TDZ 0.005 mg / L, TDZ 0.001 mg / L, CuSO4 2mM + BAP 1 mg / L, CuSO4 2mM + BAP 2 mg / L and Kinetin 1 mg / L + CuSO4 2mM. Three clumps of callus per plate with three replications were transferred to MS suplemented medium. The parameters observed were the color of callus before and after they were transfered to regeneration medium, the day of formation of globular, heart-shaped, tubular and cotyledonary phase, and the number of cotyledons formed. The results obtained showed the somatic embryogenic color of the 032 genotype was white with friable structure before being transferred to regeneration medium and was turned to yellowish white after being transferred to the regeneration medium. On the day sixth, friable embryogenic somatic of eggplant was developed into nodule on medium MS + NAA 4 mg / L, MS + CuSO4 2mM + BAP medium 1 mg / L, and MS + CuSO4 2mM + BAP 2 mg / L. Somatic embryogenic callus of accession 032 were able to pass complete globular, heart-shaped, tubular and cotyledonary phase. The most responsive medium for somatic embryogenic callus regeneration, based on the days of the callus phases formation and the number of early-phase cotyledons obtained, were MS medium suplemented with CuSO4 2mM + BAP,and CuSO4 2 mM + BAP 2 mg / L.Keywords: eggplant, Ralstonia solanacearum, regeneration, cotyledonary, clump, BAP

Abstract

Along with the increasing the of the land-use change of the fertile agricultural land in Java, the better awareness has been subjected to the importance of function peat land for agricultural development. Cassava (Manihot esculenta Crantz) is a tuber plant that potentially developed as important carbohydrate source. The objective of this research was to identify superior cassava variety candidate of selected cassava developed by of Research Centre Biotechnology, LIPI which has high adaptation capability and yield in Central Kalimantan peat land area. This research was conducted from July 2010 through May 2011 in Central Kalimantan Province (Kalampangan dan Pulang Pisau in total of area 1.5 and 2.25 ha respectively). There were three genotypes of cassava tested, i.e. Iding (high amylose), Gebang (low amylose), and Menti (high starch) compared to Adira 4 (35 ton/ha) and Darul Hidayah (102.1 ton/ha). The variables observed were plant height (cm) and tuber weight (grams). Observations were conducted at the age of 10 months. Data was analyzed using SPSS version 16.0. The results showed that the plant height and yield were higher in Pulang Pisau than Kalampangan even though the difference is not significant (P ≤ 0,05). Darul Hidayah has highest plant height and yield, 229.8 cm and 2271 g respectively among other genotypes/varieties grown at Pulang Pisau even though the value was not significant, whereas in Kalampangan, Darul Hidayah showed the lowest yield (670 g). Based on the data obtained, the Darul Hidayah variety can be cultivated by farmers in Pulang Pisau peat land to fulfill the availability of superior cassava seedlings for food, feed and industry. Keywords: Peat, tuber yield, plant height, liquid organic fertilizer, yam wood.

Abstract

ABSTRACT Drought stress is one of the major limiting factors for plant growth and production. Therefore, the mechanism of drought tolerance is important to be studied. Eggplant (Solanum spp.) is relatively tolerant to drought stress compared to other member of Solanaceae family. The objective of this study was to study the mechanism of drought tolerance in eggplant related to accumulation pattern of proline and polyamines. Seven eggplant accessions were drought stressed for 21 days and rewatered for the following next 7 days. Drought stress treatment significantly decreased the soil water content and reduced plant height of all accessions. Eggplant responded the drought stress by reducing stomatal density and stomatal opening to reduce transpiration rate. Drought stress also induced proline and polyamine (PA) accumulation in the leaf tissues. These accumulations started at 14-days after drought stress period when soil water content less than 20% and reached their peaks at 21 days after drought stress. The highest level of proline (134.70 μmol g-1) and that of putrescine (20.836 ng g-1)  could  be used as indicators for eggplant drought stress condition. Keywords: physiological responses, polyamine (PA), proline, putrescine, stomata
