title: A fast, simple, and reliable high-yielding method for DNA extraction from different plant species.
abstract: Genetic studies and pathogen detection in plants using molecular methods require the isolation of DNA from a large number of samples in a short time span. A rapid and versatile protocol for extracting high-quality DNA from different plant species is described. This method yields from 1 to 2 mg of DNA per gram of tissue. The absorbance ratios (A260/A280) obtained ranged from 1.6 to 2.0. A minimal presence of contaminating metabolites (as polymerase chain reaction [PCR] inhibitors) in samples and a considerable savings in reagents are characteristics of this protocol, as well as the low cost of the analysis per sample. The quality of the DNA was suitable for PCR amplification.
