    Development of a Competent and Trouble Free DNA Isolation Protocol for Downstream Genetic Analyses in Glycine Species
    (2016) Nawaz, Muhammad Amjad; Baloch, Faheem Shehzad; Rehman, Hafiz Mamoon; Le, Bao; Akther, Fahima; Yang, Seung Hwan; Chung, Gyuhwa
    Extraction of deoxyribose nucleic acid (DNA) from plants is preliminary step in molecular biology. Fast and cost effective genomic DNA isolation from Glycine species for downstream application is a major bottleneck. Here we report a high throughput and trouble free method for genomic DNA extraction from leaf and seeds of Glycine species with high quality and quantity. Protocol reports the optimization by employing different concentrations of CTAB and PVP in extraction buffer. Efficiency of optimized protocol was compared with frequently used DNA extraction methods. Wide adoptability and utility of this protocol was confirmed by DNA extraction from leaves as well as seeds of G. max, G. soja, G. tomentella and G. latifolia. Extracted DNA was successfully subjected to PCR amplification of five microsatellite markers and four putative glycosyltransferase genes. DNA extraction protocol is reproducible, trouble free, rapid and can be adopted for plant molecular biology applications.

    Genetic diversity and population structure of Korean wild soybean (Glycine soja Sieb. and Zucc.) inferred from microsatellite markers
    (Pergamon-Elsevier Science Ltd, 2017) Nawaz, Muhammad Amjad; Yang, Seung Hwan; Rehman, Hafiz Mamoon; Baloch, Faheem Shehzad; Lee, Jeong Dong
    Korea is considered one of the centers of genetic diversity for cultivated as well as wild soybeans. Natural habitats of wild soybeans are distributed across the Korean mainland and the islands surrounding the Korean peninsula. In this study, the genetic diversity of 100 mainland Korean wild soybean accessions was evaluated by using 42 simple sequence repeat markers covering 17 soybean chromosomes. All analyzed loci were polymorphic and a total of 114 alleles were found. The observed average genetic diversity was low (0.4). The results showed that the 100 selected accessions did not exactly follow the geographical distribution. These results were further confirmed by the phylogeny inferred from five morphological characteristics (i.e., leaf shape, leaf area, plant shape, seed area, and 100-seed weight). Together, the genetic and morphological evaluations suggested conclusively that the selected population did not follow the geographical distribution pattern. The present study could provide useful information for the ex situ conservation and exploitation of wild soybean accessions in soybean improvement stratagems, and will aid in further understanding about the phylogeography of the species in the Korean center of diversity.
