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.

DNA Agarose Gel Electrophoresis
Gel extraction follows five major steps: running gel electrophoresis to separate fragments, isolating the individual bands, extracting DNA from those bands, and removing the dye and salts from the extracted mixture to obtain pure DNA.
In cloning experiments, both the insert and vector DNA...
