An efficient protocol for total DNA extraction from the members of order Zingiberales- suitable for diverse PCR based downstream applications

Abstract

Different protocols are usually used for extracting total deoxyribonucleic acid (DNA) from different plant species of same order and DNA of the associated viruses. Here, we describe a rapid, efficient and universal protocol for isolating total DNA from the members of Zingiberales which harbor a high amount of polysaccharides and secondary metabolites. DNA isolated with this protocol was successfully used for PCR based downstream applications viz. random amplified polymorphic DNA (RAPD), Inter-simple sequence repeats (ISSR), DNA barcoding gene (Internal transcribed spacer and trnl-f) amplification and detection of the viruses. © 2013 Devi et al.; licensee Springer.
