Barley tissue as direct template for PCR: a practical breeding tool
1996
A method for using alkali treated intact plant tissue as a DNA source for the polymerase chain reaction (PCR) was applied to barley. This method saves up to two days and more than USD 50 per 40 samples by eliminating the need for DNA extraction to produce template for PCR. The conditions were optimized for various barley tissues. Fresh leaves, freeze-dried leaves, and anthers worked well as templates while root, embryo, and endosperm tissues did not. The method was shown to work with several genotypes and different primers. The resulting PCR product could be cut with restriction enzyme to produce clear polymorphism without any interference. This method can be a practical breeding tool by providing a fast, inexpensive method for screening large populations.
