Download our ebook: From DNA Extraction to PCR, Plant DNA extraction needs a CTAB DNA extraction buffer that contains ingredients that can effectively remove polysaccharides and polyphenols. The CTAB procedure would likely work with many gram-negative strains without modification, but gram positives would likely require the addition of lysozyme and proteinase K steps, and may also require modification of medium eg. Since DNA is insoluble in these alcohols, it will aggregate together, giving a pellet upon centrifugation. Prepare a 10X stock for CTAB solution to avoid repeated chemical preparation. Major ingredients of CTAB buffer are CTAB, Tris, EDTA, beta-mercaptoethanol, PVP and NaCl salt. In addition, the presence of turgor pressure, all these things creates problems in plant DNA extraction. The method needs to be modified for use on Gram-positives or yeast etc, by adding on extra lysis treatments at the 'front end' of the protocol. Its better to leave a trace of ethanol and water in the pellet (and have it dissolve easily), than to remove all moisture, and then have great difficulty dissolving the pellet. This research evaluated five genome extraction methods including Protocol A (main CTAB), Protocol B (CTAB without -mercaptoethanol), Protocol C (CTAB without ammonium acetate), Protocol D (modified method of Murray and Thompson), and Protocol E (Gene All-Kit), to determine their ability to extract DNA from fresh and herbarium leaves of A. fridae.
