Abstract

The SoSPS1 gene of sugar cane plants previously subjected to Agrobacterium tumefacienmediated cloning was to be transferred to citrus plants to increase metabolism of sucrose in plant. The T-DNA harbored the SoSPS1 gene under the control of the CaMV 35S promoter from the cauliflower mosaic virus and contained the NPTII gene (kanamycin resistance gene) as a selectable marker for transformant selection. Generally, gene transformation in plants is carried out by tissue culture. However, tissue culture has several disadvantages such as its being time-consuming, its sometimes resulting in somatic mutations and somaclonal variations, and the requirement of sterile conditions in the procedure of gene transfer. In planta transformation is a useful system for those plants that lack tissue culture and regeneration system. The main function of in planta transformation is to recover the advantages of tissue culture as an efficient, quick method, including its ability to produce a large number of transgenic plants and to accumulate a high concentration of total soluble protein in short time. There are two procedures of in planta transformation for the seeds of citrus plants, namely “prick and coat” and “seed tip-cutting and imbibition”. In the prick and coat method, seeds are pricked on their entire surfaces and smeared with a suspension of Agrobacterium tumefaciens. In the seed tip-cutting and imbibition method, on the other hand, seeds are cut at the tip and soaked in a suspension of Agrobacterium tumefaciens. The leaves derived from seeds treatment were taken as samples for DNA extraction and PCR using primers of the NPTII gene (Forward: 5’-GTCATCTCACCTTCCTCCTGCC-3’; Reverse: 5’-GTCGCTTGGTCGGTCATTTCG-3’). This research found that only the seed tip-cutting and imbibition plants amplified along the 550-bp band, while those of the prick and coat method did not. Additionally, the T-DNA was successfully integrated into the genome of the plants treated with the seed tip-cutting and imbibition method but not with the prick and coat.

Abstract

Creation of new superior varieties of mango through the empowerment of local genetic resources requires information about the potential properties of mango germplasm, including DNA polymorphism and its genetic diversity. This research aimed to obtain basic data on DNA polymorphism, genetic relationship, genetic similarity level, and molecular accession of Bali’s unique local mango. Sampling was conducted in four regencies in the Province of Bali. DNA preparation, PCR, and microsatellite analysis were carried out at the Laboratory of Genetics and Plant Breeding, Faculty of Agriculture, Gadjah Mada University. It found 44accessions of mangoes in Bali. The test results with 10 pairs of SSR markers showed that all primers produced polymorphic loci. There were 825 amplified DNA bands. Primer of AY31 produced the highest number of loci, which were 14 loci, while AY21 produced the fewest loci, i.e., 3 loci. Forty-four mango accessions showed a genetic similarity coefficient of 0.27 to 0.97. At a coefficient of 0.27, accessions were divided into 2 major groups: group A and group B. Group A consisted of two accessions, namely, KRA-005 and BDG-006 (Mangifera foetida Lour.), which had a similar coefficient of 0.657. Group B was divided into twosmaller groups, namely, groups B1 and B2, at a similarity coefficient of 0.342. Group B1 consisted of 39 accessions, while group B2 consisted of 3 accessions. Accessions Madu Anggur, Gading, Sambuk Mengwi, Kakul and Pakel Sulangai were identified as having unique alleles.

Abstract

Research on doubling plant chromosome using colchicine has been carried out for years with water as its solvent. In this study, an innovation was carried out by trying to do colchicine treatment in hydrogen peroxide. In this in vivo induced mutagenesis research, colchicine in hydrogen peroxide was administered as mutagen on seeds three species of crops i.e. mutan M2 cowpea, yardlong bean, and common bean by soaking method. The results of this research showed that three times multistep mutant (M3) of cowpea was having mutant characteristics that the shape of its leaflet changed from rhombus to ovate. Besides, both yardlong bean varieties used in this research (BLR and KTR) showed indication of a mutant crop that having compound leaves with more than three leaflets in a stalk. Common bean of PTW variety was not attacked by any aphid but it was attacked by leafminer. Finally, we found “rainbow common bean” from this research.

Abstract

Essential oil production in the market is very diverse with various brands labeled as antioxidants that have gained more attention in the society recently. The purpose of this study was to analyze limonene and other antioxidants content of the essential oils in the market compared to homemade virgin coconut oil. The method used was Gas Chromatography-Mass Spectrometry (GC-MS) and Fourier-transform infrared (FTIR) Spectroscopy. The infrared spectrogram showed the presence of alkanes and esters respectively at wave numbers of 3000-2850 and 1750-1730 cm-1. Chromatogram results showed the presence of limonenecompounds and some antioxidants with a fairly good separation in the several types of oils, which was not detected in the homemade virgin coconut oil.

Abstract

Increasing the productivity of soybeans in dry land can be done by designing a package of fertilizer technology based on biological materials using indigenous endomycorrhiza and Rhizobium. The application of indigenous endomycorrhizal biofertilizer combined with Rhizobium is expected to be able to improve nitrogen and phosporus uptake so as to increase the productivity of soybeans in dry land. The experiment used two-factor factorial randomized block design. The first factor was dose of endomycorrhizal spores of Glomus that consisted of four levels, namely, treatment without endomycorrhiza inoculation, dose of 50endomycorrhizal spores, dose of 100 endomycorrhizal spores, and dose of 150 endomycorrhizal spores. The second factor was inoculation of Rhizobium inoculum that consisted of two levels, namely, treatment without Rhizobium inoculation and Rhizobium inoculation. The results showed that combination of 50 endomycorrhizal spores with Rhizobium inoculation gave the best effect on the number of effective root nodules per plant, endomycorrhizal infection per plant, nutrient uptake by plant, number of pods per plant, number of seeds per plant, and oven-dry weight of seeds per plant.
