5.2) along with chloroform:isoamylalcohol extraction helped in better removal of polysaccharides and proteins. Overnight incubation at –40 °C increased the yield of DNA. The yield of DNA was in the range of 5–8.1 µg g–1 of dried bark. The absorbance ratios at 260/280 nm and 230/260 nm were higher than 1.8 and 2, respectively, indicating the
good quality of the DNA. The quality of the DNA was also checked on 0.8% agarose gel electrophoresis (Figure 3). Complete digestion of DNA by both the enzymes (EcoR V and Hind III) confirmed the purity of DNA (Figure 4). RAPD analysis performed as per the method of Williams et al. (1990) modified by Syamkumar (2008), produced a distinct banding pattern (Figures 5a–5c). Amplification of genomic DNA using the universal primers for the rbcL locus coding for the large subunit of the RUBISCO enzyme produced a band of 600 bp (Figure 6). This band may be further sequenced to detect SNPs or indels specific to the species. Amplifications of the DNA further confirmed that the DNA is of high quality, free from polysaccharides and other contaminants.
