Abstract

Rice varieties tolerant to drought stress are needed tostabilize rice production under drought stress condition. Wedeveloped transgenic rice cv. Nipponbare carrying hptIIgene that might also contain OsDREB1A gene. OsDREB1Agene responsible to drought tolerance trait need to betransferred into cultivated rice in order to obtain new localrice variety tolerant to drought stress. The aims of thisresearch were to detect the presence of hptII gene in the F1and BC1F1 transgenic rice and to observe the agronomicperformace of those populations and their plant physiology.F1 population was developed by crossing transgenicNipponbare, as donor parent, with Batutegi, Code, Ciherang,and Konawe genotypes, as recipient parents. BC1F1population was developed by backcrossing F1 transgenicline with recipient parents, respectively. The presence ofhptII gene was analyzed by PCR using a pair of primers forhptII. The observation of agronomic performance wascarried out in the green house, meanwhile the observationof stomata was done using microscope. The result of PCRanalysis showed that BC1F1 Batutegi trans, BC1F1 Code trans,BC1F1 Konawe trans1, BC1F1 Konawe trans3, dan BC1F1Konawe trans4 were detected carrying the hptII gene.Agronomic data showed that BC1F1 transgenic rice linesyielded panicles, filled grains, and total grains higher thanthose of recipent parents. Comparing to the recipientparents, BC1F1 Konawe trans1 and BC1F1 Konawe trans3 hadless stomata on the lower side of the leaf, but had morestomata on the upper side of the leaf.

Abstract

Mango is one of the fiveimportant fruit crops in the world. Microsatellite markers canbe used to analyze genetic diversity among mangoaccessions. The purpose of this research was to determinethe relationship among mango germplasm collection usingmicrosatellite markers. A total of 161 mango accessionsoriginated from Indonesian Tropical Fruit Research Institute(Cukurgondang Field Station), Pasuruan, East Java, wereused in this research. Twenty-six microsatellite markerswere used to genotype each accession. Genotyping wasconducted using Beckman Coulter® CEQ™ 8000 machine.Genetic relationship among accecions was analyzed usingthe Unweighted Pair Group Method with Arithmetic Mean(UPGMA) method, followed by bootstrap analysis. The resultshowed that high allele variation (15-75 alleles) wasobserved among mango accesions tested, with an averageallele number of 38.69. The average of PolymophismInformation Content (PIC) value was 0.548 (0.021-0.949).Fifteen microsatellite markers showed PIC value >0.5indicated that these markers were suitable for mangodiversity studies. Cluster analysis divided the mangocollections into two groups. Group I consisted of 95accessions, and group II consisted of 66 accessions. NinetyIndonesian indigenous mangos (84.11% of Indonesianmango accessions) could be separated from the introducedaccessions.

Abstract

To support the government policy inimproving soybean production, it is suggested to plant earlymaturing (<80 days), drought tolerant and high yieldingvarieties to be applied in the cropping system of rice-ricesoybeanand rice-rice-rice-soybean in lowland, and indryland cropping system of rice-soybean or rice-otherpalawija crops. Mutation breeding in soybean for earlymaturity and high productivity in soybean can be applied toobtain some new varieties. The breeding proceduresincluded selection using bulk method for M1 population,followed by the pedigree method for M2-M5 generations.Evaluation of uniformity (homozygous) of lines is done onthe M4 generation. Yield and adaption testing are conductedduring M5-M8 generations. Through mutation breeding earlymaturity soybean varieties were released elsewhere. Innational research institutes such as The National NuclearEnergy Agency (Batan) Indonesia, soybean mutation breedingactivities were begun since 1972, while in IndonesianCenter for Agricultural Biotechnology and GeneticResources Research and Development (ICABIOGRAD), itwas started in 2009. Batan has released two early maturingsoybean varieties through seed irradiation such as Tenggerin 1991 and Meratus in 1998. While in 2011 ICABIOGRADthrough irradiation of calli-derived embryo zygotic hasselected 50 early maturing and potentially yielding soybeanmutant lines. While through seed irradiation in 2012, 15soybean advanced lines that matured earlier anddemontrated higher yield were also obtained.

Abstract

Activation tagging is an efficient tool forfunctional analysis of the rice genes. We have developed anumber of transgenic rice lines (Oryza sativa L. ssp.japonica cv. Taipei 309) containing activation tagging vector.However, the phenotypes and genotypes of these lines, inrelation to the drought stress, have not been analyzed. Theobjectives of this research were to identify transgenic ricelines that showed tolerance to the drought stress and toidentify the genes that may be associated with the droughtstress. The drought stress tolerance in transgenic rice lineswas identified by testing their tolerance to the drought stressand also by detecting the presence of bar and nptII genes.The result showed that 56 out of 59 rice lines were resistantto Basta herbicide and three of them showed tolerance todrought stress, namely PA.T-1.2, PA.T-4.1, and PA.T-5.1 lines.PCR analysis showed that PA.T-1.2 and PA.T-4.1 containedboth hptII and bar genes, while the PA.T-5.1 line containedbar gene only. Thermal Asymetric Interlaced-PCR (TAILPCR)analysis showed that two genes may be asssociatedwith the drought stress tolerance. Those genes areOSJNBa0004120.14 that produces uridylate putative kinaseand OsPPCK2L that produces phosphoenolpyruvatecarboxylase kinase.

Abstract

The activation-tagged populations of transgenic rice cv.Asemandi have been developed by introducing construct ofactivation taq Ac/Ds into rice genom of cv. Asemandi. The T1transgenic rice populations cv. Asemandi containingconstruct of activation taq have been obtained and neededto be characterized. This study aimed to identify the Bastaherbicide resistant plants, transgenic plants containing hptand bar genes, and changes in agronomic traits. Bastaresistant plant was identified by treating leaf with bastasolution. Hpt and bar genes were detected by PCR usingspecific primers. Phenotype characters were identified byobserving and measuring their agronomic parameters. Thestudy results showed that out of 315 rice transgenic cv.Asemandi T1 treated with Basta solution, 176 (55.87%) plantswere indicated to be resistant to Basta. The results of PCRanalysis revealed that eight rice transgenic cv. Asemanditested contained both hpt and bar genes. In general,compared to the nontransgenic plants, there were changesin several agronomic parameters of T1 transgenic plants cv.Asemandi, including plant height, days to flowering, days toharvesting, periods of grain filling, and weight of 100 grains.Correlation analysis showed that there was no correlationbetween days of harvesting to weight of 100 grains intransgenic rice, but there was correlation in nontransgenicrice. Transgenic rice plants cv. Asemandi with changes inthe agronomic characters will be useful for further study,such as to analyze the function of the genes.
