Abstract

Various protocols are usually used for extracting genomic DNA from plants for genetic analysis. Majority of currently used 
DNA extraction methods and commercially available kits are multi-stepped, time consuming, expensive especially when 
dealing with large number of samples. In the present study, we have developed a universal method for extracting DNA from 
various parts of different plants which is inexpensive, quick and easy. In this method, to extract the DNA, 0.5% SDS, 0.5 M 
NaCl, 0.5% PVP and 100mM Tris HCl (pH 8.0) were used in the buffer. Leaf samples were ground with 50µL of buffer in 
1.5 ml tube and was stabilised with 1000µL of 100mM Tris-HCl buffer. 2µL of lysate from this extract was used for setting 
PCR. The method doesn’t require hazardous chemicals or purification procedures. The DNA extracted was found to be 
sufficient and suitable for PCR amplification with high reproducibility.
