The extraction of high-quality DNA is essential for studies conducted at the molecular level in species with an abundance of contaminants in their tissues, such as some landraces of potato and maize, in which it is difficult to extract good-quality genomic DNA. Compounds such as polyphenols interfere with the amplification of DNA during polymerase chain reaction (PCR), which makes it difficult to conduct PCR-based studies ofmolecular markers. This article describes a simple and robust protocol for DNA isolation that was applied to potato and maize landraces and resulted in a high DNA concentration with excellent purity and quality. This method is based on the method of Krizman et al. (2006) with some modifications and was tested on potato leaves and young... |
