Technical Abstract: Three general methods that are commonly used to extract genomic DNA from plant tissue were reviewed. The principles, critical factors, and optimization procedures were discussed to help researcher to choose and modify a method according to their research purpose. Emphasis is given to a simple 96-well plate based high throughput DNA extraction method that is applicable to many plant species. The method involves a simple incubation of plant tissue samples in a DNA extraction buffer followed by a neutralization step. With the addition of a modified PCR reaction buffer, the extracted DNA enabled the robust amplification of genomic fragments from samples of Arabidopsis, tobacco, sorghum, cotton, moss, and even pine needles. Several thousand DNA samples can be economically processed in a single day by one person without the use of robotics. This procedure will facilitate many technologies including high throughput genotyping, map-based cloning, and identification of T-DNA or transposon tagged mutants for known gene sequences.
