Genetic Diversity Analysis

Probiotics are live, non-pathogenic microorganisms which have enormous health benefits. Yogurt is a potential source of probiotic bacteria. Lactic acid bacteria are the most common and major group of probiotic bacteria that can be found easily in different dairy products. The aim of study was the genetic diversity analysis using random amplified polymorphic DNA (RAPD) marker from regional yogurt samples of Bangladesh. Ten probiotic isolates from yogurt samples of different sweet meat shops of Sylhet and Mymensingh Divisions of Bangladesh were used. Morphological and biochemical tests were performed to ensure the presumptive probiotic characteristics of isolated bacteria. All isolates were cultured in De Man, Rogosa, and Sharpe (MRS) medium to exhort the growth of lactic acid bacteria. Genomic DNA was extracted by Ampicillin Lysozyme Tandem method. Four random RAPD primers were used in this study for detecting genetic diversity of these isolated bacteria. Among them, OPA 18 showed the maximum number of reproducible bands. Nei’s genetic distance was performed for determining Pair-wise Genetic Distance. UPGMA and NJ dendrogram were performed based on molecular data showing that all the isolates could be divided into two major clusters. Data analysis revealed that isolates from the same location were closely related and showed less genetic variation whereas, isolates from geographically different regions exhibited more genetic diversity.

Determination of annealing temperature of the primer is the first step for genetic diversity analysis using molecular markers such as RAPD (Random Amplified Polymorphic DNA). This study aims to determine annealing temperature (Ta) of RAPD primers on Kampar Mungbean. Methods included total DNA extraction, electrophoresis, and annealing temperature optimization of four RAPD markers namely OPD-20, OPI-06, OPI-13, dan OPX-13. Optimization was conducted by reducing the Tm value (Time melting) of each primer with 3 (Tm-3) and 5 (Tm-5). The results showed that the optimization using OPD-20 and OPX-13 produced bands at Tm-3 and Tm-5. Meanwhile, optimization using OPI-06 and OPI-13 resulted in bands at Tm-3. The next step was to choose the exact Ta based on the clear and bright band. In conclusion, exact Ta for OPD-20, OPI-06, OPI-13, and OPX-13 were 36,1°C, 38,1°C, 35,4°C, and 32,5°C respectively.

ABSTRACT Lengkong, E.F. and S.D. Runtunuwu. 2005. Use of Molecular Marker Random Amplified Polymorphic DNA (RAPD) to Genetic Diversity Analysis of West African Tall (WAT) Coconut. Eugenia 11 (3):210-217.   Information on genetic diversity of crop gemplasm has several important implications for plant breeder. Among others is to help the breeders to decide what sources to cross so as to making new genetic combination. The use of molecular marker to genetic diversity analysis on DNA level is usefull, because it provides an opportunity to more precisely measure genetic relationships as well is not affected by the environment. The objective of this research was to analyze genetic diversity of West African Tall (WAT) using molecular marker RAPD. Five arbitrary 10-mer primers were used to amplify total DNA genom, and to generate 44 band DNA with 26 band or 59 % were polymorphic band. It was revealed that genetic diversity within population of WAT coconut was 14 %. Based on cluster analysis, at the genetic similarity 85% or genetic diversity 15 % the population was separated on three clusters. This research concluded that the population of WAT coconut grown from open pollinated seeds has different genotype one each others. Keywords: West African Tall (WAT), Coconut, RAPD
