CTAB-based DNA extraction for citrus v1

CTAB-based protocols are used for genomic DNA extraction from many kinds of plant species. However, the protocols can’t necessarily completely remove contamination of polysaccharide and RNA in extracted genomic DNA solution. Especially, citrus leaves generally contain high polysaccharide. This protocol is a simple and efficient method for extracting genomic DNA for citrus without contamination of polysaccharide and RNA.
