Extraction of high-quality genomic DNA fromGossypium (cotton) species is difficult due to high levels of polysaccharide, oxidizable quinones, and other interfering substances. We describe a procedure that consistently permits isolation of cotton genomic DNA of satisfactory size and quality for RFLP and PCR analysis, as well as for most routine cloning applications. Several antioxidants, phenol-binding reagents, and phenol oxidase inhibitors are used throughout the procedure, and most polysaccharides are eliminated early in the procedure by isolation of nuclei.
