Abstract

Deltamethrin is an active ingredient of insecticides such as decis, and its common pollutant observe in agricultural soil.  Microbes that able to degrade deltamethrine and produced IAA as plant growth promoting hormone is important to support organic agriculture. The aim of this study was to find deltamethrin degrading bacteria capable of producing IAA and to evaluate  the effect of nitrogen on degradation rate of deltametrin and IAA production. Deltametrin degrading  Bacteria was  isolated from non-organic rice fields around Cibinong Science Center. Deltamethrin degradation ability was evaluated in NMS medium with the addition of a nitrogen source: yeast extract, urea and NPK. Analyses of 16S rDNA showed that deltamethrin degrading bacteria and producing IAA was identified as Pseudomonas sp. PIV-8-2. Nitrogen siginificantly affect the degradation deltametrin rate, but not on  IAA production. Only on the addition of yeast extract and urea significanly  affect to IAA production after 2 days incubation.Keywords: Deltamethrin Degradation, IAA, Pseudomonas sp. PIV-8-2, Farming.

Abstract

Maize (Zea mays L.) has become second most important cereal crops after rice in Indonesia. Maize is a staple foodand the main crop in subsistence dry land farming system in Nusa Tenggara Timur (NTT). Previous survey suggestedthat NTT may have contained considereable amount of local landraces of maize that have not been wellrecorded. Traditional farmers prefer to use traditional landraces than popular hybrid maize due to their superiorfeatures such as less susceptible to weevil attack and well adapted to local environment. Hence, farmers were continuouslygrow local landraces to meet the demand for their food security. Information on diversity of local landracesis very important for improving landrace germ plasm. The objective of this study is to assess genetic andphenotypic diversity of 15 accessions of maize from nine putative landraces collected from six locations in NTTbased on Inter Short Sequence Repeat (ISSR) fingerprints and few morphological charcters. Five ISSR’s primers(UBC 809, 822, 834, 876 and 892) were initially screened and two (UBC 809 and 834) were selected for the analysis.These primers generated 16 scorable bands with two monomorphic bands, i.e. UBC 809 at 700 bp and UBC834 at 900 bp. Clustering analysis was performed based on ISSR profiles using the UPGMA method. The range ofgenetic similarity value among accessions was 0.30-0.80 suggesting sufficient variation of gene pool existed amongaccessions. Combined data set of ISSR and morphological data suggested a higher diversity with a cofficient ofdistance range from 0.52 to 1.25. Same as a single data set deduced from ISSR profile, none of the accessionswere clustered according to their landraces nor their progeny.Keywords: Maize, NTT, ISSR, genetic diversity

Abstract

Genetic Diversity of Sambar Deer (Rusa unicolor) in Utilization and Implications for Conservation. The deer sambar (Rusa unicolor) is one of species of Genus Rusa, was widely distributed in South Asia antil South East Asia. This species in Indonesia was widely distributed in Kalimantan and Sumatra island, but now, the hunting, poaching and habitat loss have reduced its populations drasstically. In order to provide useful information for its conservations. The genetic diversity and population structure of the wild sambar deer was observed by analyzing the 962 bp long of fragment mitochondrial DNA (mtDNA) control region (D-loop)fragment. The result detected, twenty different haplotypes from 22 samples from Borneo and Sumatra. Overall, sambar deer have a relatively high genetic diversity compared to other the ceervid species, with a haplotype diversity (h) 0.9870 and nucleotide diversity (ð) 2.931±0.260%.The genetic distance of Borneo populations (East Borneo) higher compared with Sumatra’s populations that is d = 0.018±0.003 on Borneo and d = 0.009±0.002 on Sumatra. The structure of phylogenetic tree showed that two populations were separate based on the haplotypes differences.Keywords: conservation, control region, genetic diversity, sambar deer.

Abstract

Artemisia annua L. is known as one of the plants producing artemisinin, i.e. active compound that is used for anti-malaria theraphy. This plant has potency to be cultivated in Indonesia through seedlings and cuttings. The objective of  this study was to compare growth and biomass allocation of plants from seedlings and cuttings. The experiment was set using  Completely Randomize Design with one factor. The factor is type of plant propagation which cutted plant derived from three different ages of mother plants (1.5, 2, and 2.5 months after planting) and seedlings as control. The result showed that growth and biomass alleviation of the cuttings plants are more rapid than the seedlings. However, the cutting plants were flowering earlier than the seedling. At three months after planted, more than 70% of the cutting plants population have flowered. It is implied that the plants from cutting will loss about 70% of its yield potency than the seedling. On the other hand, there was no significant effects of the ages of mother plants on growth and biomass of the cutted plant (p>0.05). Therefore, seedlings were more effective than cutted plant on A. annua cultivation. Keywords: artemisia annua L., biomass allocation, cuttings, growth, seedlings.

Abstract

ABSTRACTPreliminary study: Gene transfer from transgenic potato Katahdin RB to non transgenicpotato. One of the concerns associated with the release of transgenic crops, is the possibilityof the gene flow from transgenic crops to neighboring crops of the same species or to relatedspecies. In plants, gene flow is a routine process occur through the natural hybridization. Theopportunity for gene flow occur depends principally on two factors, the degree of sexualcompatibility between donor and recipient species, and the physical distance between thetwo. The experiment was conducted to determine whether the gene flow from transgenicpotato Katahdin RB to non transgenic was occurred, based on selection using a 50 mg/lkanamycin, and to estimate gene flow mediated by natural hybridization at different isolationdistances. Preliminary result indicated that a rapid and simple method using MS0 liquid mediawith kanamycin 50 mg/l was effective for screening the seeds. There was a gene flow fromtransgenic potato Katahdin RB to non transgenic, based on a rapid and simple selectionmethod using 50 mg/l of kanamycin as selectable marker. The isolation distance used in thestudy were 0.8, 1.6, 2.4, 3.2, 4.0, 4.8, 5.6, 6.4, 7.2, 8.0, 8.8, 9.6, 10.4, and 11.2 m from the row oftransgenic potato Katahdin RB. The gene flow through natural hybridization at a isolationdistances of (0.8 - 1.6 m), (2.4 – 4 m), and (4.8 – 6.4 m) from transgenic to non transgenic plantswere 13.78, 10.92, and 3.82%, respectively. At a distance of 7.2 – 8 m, the frequency of gene flowwas declined to 0%. The frequency of gene flow from transgenic potatoes to non transgenicpotatoes markedly decreased by increasing the isolation distance, and was negligible at 7.2 m.Key words : natural hybridization, transgenic potato RB, kanamycin selection
