Abstract

Mutation induction with chemical mutagen ethyl methane sulfonate (EMS) capable of producing genetic variation in plants. The purpose of this research was to evaluate genetic variation of EMS-induced chili pepper mutants using SSR molecular marker. Various concentration of EMS (0.01%; 0.02%; 0.04%) were applied to chili pepper seeds of Genotypes 2, 7, and 11. The genomic DNA was isolated from mutants and control plants then used for PCR analysis using three SSR primers namely CA26, CA52 and CA96. The three SSR primers were able to detect genetic variation in the three genotypes of EMS-induced chili pepper mutants and control plants. A total of 18 alleles have been identified in all three SSR loci with PIC values ranging from 0.792 to 0.893. The three genotypes of chili pepper plants had different sensitivity to EMS mutation induction. Genotype 11 plants showed higher sensitivity to EMS treatment than genotypes 2 and 7 based on the amount of genomic changes. Dendrogram constructed based on genetic similarity values distributed the mutants and control plants into three main groups with similarity coefficients ranging from 0.34 to 0.90. Similar genotype either control plant or mutants, especially Genotypes 2 and 7 were group into similar group. However, for the Genotype 11 plants, large genome changes cause mutant plants G11K1, G11K2, G11K3 had a low genetic similarity to their control plants, so the mutants were separated in a different group from the control plant. Those indicate that EMS mutation induction capable of increasing genetic variation in chili pepper plants based on SSR molecular marker.

Abstract

ABSTRAKPertimbangan dalam pemilihan metode ekstraksi untuk mendapatkan senyawa bioaktif dari bahan tanaman diantaranya adalah efisiensi waktu dan jumlah pelarut yang digunakan. Studi terdahulu menunjukan ekstraksi bahan aktif dengan gelombang mikro mempercepat waktu ekstraksindan menghemat penggunaan pelarut dibandingkan metode konvensional, tetapi waktu ekstraksibyang terlalu singkat dan penggunaan pelarut yang terlalu minim membuat hasil ekstraksi tidaknoptimal. Penelitian ini untuk mengetahui pengaruh rasio bahan:pelarut dan lama ekstraksi dengan gelombang mikro terhadap kandungan fitokimia dan aktivitas antioksidan dari ekstrak cabai rawit. Penelitian dilakukan menggunakan Rancangan Acak Kelompok 2 faktor yaitu rasio bahan:pelarut dengan variasi 1:5; 1:10; dan 1:15, serta lama ekstraksi (5, 10, dan 15 menit). Berdasarkan hasil pengujian, rasio bahan:pelarut 1:10 memberikan hasil terbaik untuk kadar total capsaicinoid, total fenol, total flavonoid, dan aktivitas antioksidan dengan nilai rata-rata sebesar 138.06 ± 6.35 mg CE/g BK ekstrak, 33.75 ± 1.75 mg GAE/g BK ekstrak, 205.41 ± 26.13 mg QE/g BK ekstrak, dan 447.96 ±25.63 μg/ml. Lama ekstraksi untuk menghasilkan nilai total capsaicinoid dan total fenol paling tinggi adalah 5 menit, sedangkan untuk total flavonoid pada waktu 10 dan 15 menit. Nilai IC50 memiliki korelasi yang linear dengan total capsaicinoid, total fenol, dan total flavonoid. Pemilihan perlakuan terbaik dengan metode multiple atribut menunjukan rasio bahan:pelarut 1:10 dan lama ekstraksi 10 menit merupakan kombinasi perlakuan paling optimal untuk ekstraksi senyawa fenol menggunakan Microwave Assisted Extraction ABSTRACTThe consideration of extraction methods to obtain bioactive compounds of plant origin were the time efficiency and the amount of extraction solvent. Previous studies showed that microwave assisted extraction of active ingredients decrease the extraction time and minimize the solvent compared to conventional methods, but short extraction time and less solvents make extraction less optimal. The aim of this study to determine the effect of materials:solvent and extraction time of microwave assisted extraction to phytochemical content and antioxidant activity of the cayenne pepper extract. The study was conducted using a Randomized Block Design 2 factors of the ratio of material:solvent (1:5; 1:10; and 1:15) and extraction time (5, 10, and 15 min). The results showed that material:solvent ratio of 1:10 gave the best value for total capsaicinoid content, total phenol, total flavonoid and IC50 with average value of 138.06 ± 6.35 mg CE/g DW, 33.75 ± 1.75 mg GAE/g DW extract, 205.41 ± 26.13 mg QE/g DW extract, and 447.96 ± 25.63 μg/ml respectively. The optimal extraction time to generate total capsaicinoid and total phenol content was 5 minutes, while the optimal extraction time for total flavonoid was 10 and 15 minutes. IC50 in this study had a linear correlation with total capsaicinoid, total phenol, and total flavonoid. The best treatment with multiple attribute method showed the materials:solvent ratio of 1:10 and extraction time of 10 minutes was the most optimal treatment combination for extraction of phenol compound by microwave assisted extraction

Abstract

Background: The relationship of plant kinship can be done through the identification of the phenotype character that is the character that appears on the individual or plant organism that can be both quantitative and qualitative. The purpose of this research is to know the diversity and kinship of corn cultivar from Kisar Island Regency of Maluku Southwest of Maluku Province based on phenotype character. Methods: The genetic material used was six local corn cultivars and one comparative variety. The six local corn cultivars are Red ruby with a brown cob, Blood red corn, Sticky, Ripe yellow, Deep yellow, and White, while the varieties are Srikandi varieties. To know the effect of cultivars and corn varieties on phenotypic diversity, variant analysis with Statistica Analytical System (SAS version 9.0) was used. To know the character that gives the greatest contribution to the diversity of cultivar phenotype and corn varieties, the main component analysis is done. To know the kinship among corn cultivars based on phenotypic character, gross analysis (cluster analysis) with hierarchy method is performed. The main component analysis and gameplay analysis was performed using SPSS version 18.0 computer program. Results: The results of variance analysis showed a significant effect of maize cultivar on phenotypic diversity. Characters that contribute to the diversity of the corn cultivar phenotype are the proline level, the weight of cobs without harvesting at harvest, the weight of cobs without dryness of the oven, the weight of the cobs at 12% moisture content, the unleaded cobs at 12%, the diameter of the ear, the number of seeds per ear, the number of rows of beans per ear, the number of leaves, and the length of the leaf. The results of Euclidean and Euclidean girder analysis show that the local yellow cultivars are in one group alone and have a low similarity with other local corn cultivars as well as the Srikandi-based varieties based on their phenotypic characters. Conclusion: There is a variety of phenotypes of local corn cultivars and varieties of Srikandi compounds grown on Kisar Island of Southwest Maluku Maluku Province.

Abstract

A breeding program of Mango (Mangifera indica) was organized by a team of Brawijaya University since 2006 by cross pollination between Arumanis 143 (green skin) with yellow skin cvs. of Carabao, Haden, Podang and Swarnarika in vice versa. As early identification a molecular evaluation was conducted. Measurement were on carotene content, DNA analysis using PCR and sequencing. The result showed that mango cultivars having orange or yellowish skin contain carotene higher than those mango cultivar having green skin. SCAR18 marker as a sign on the presence of beta (B) locus in tomato was not related with the differences of beta carotene accumulation in those manggo cultivars. SCAR18 marker that was amplified in mango produced specific amplimer of 320 bp in length. The similarity of SCAR18320 sequence obtaining by sequences alignment among five parental cultivars and 12 hybrids was up to 100%. SCAR18320 sequences that were generated by SCAR18 markers as predicted beta (B) loci had no significant similarity with sequences database relating to beta (B) gene in NCBI. SCAR18320 match to 19 Ty3-gypsy retrotransposons and others sequences related transcriptional regulator in more dissimilar sequences (discontiguous megablast) category.Keywords: SCAR18, ? carotene, skin color, Mangifera indica
