Konstruksi dan Analisis Kualitas Pustaka Genom Kedelai (Glycine max (L.) Merr.) untuk Sekuensing Genom Total

Abstract

Soybean is one of the most important agricultural commodities in the supply of food in Indonesia. However, the low of the national soybean productivity is a constraint in soybean cultivation in Indonesia. National soybean productivity can be increased by genetic improvement of plants. Whole genome sequencing and genomic analysis of soybean is one way to accelerate soybean breeding progress and improve understanding of genetic and genomic information of soybean. Purposes of this research were to construct genomic library of three Indonesian soybean genotypes (Tambora, B3293 and Grobogan) and analyze the quality of the genomic library on whole genome sequencing result. Construction of genomic libraries was carried out in vitro by attaching an adapter to the end of DNA fragments. Clasterization and sequencing of genomic library in this research were conducted by using cBOT claster generation dan Next Generation Sequencing HiSeq2000. Genomic libraries were constructed successfully sized 400 bp with a concentration of 23.20 ng/μL (Tambora), 64.50 ng/μL (B3293), and 21.20 ng/μL (Grobogan). Size and concentration of the constructed genomic libraries were suitable for whole genome sequencing. The total yield of bases generated from the sequencing was 50.1 x 109 bp. Cluster library produced during the process of genome sequencing was Q scores value above 30 was 88.6%. Error rate of base reading during the sequencing was 0.97%. Values of the cluster density, percent cluster PF, the intensity of the base, phasing percent, and prephasing percent generated from this research showed that the cluster quality of genomic libraries was of ideal category.
