M. Huang, Sun, X. J., Zhou, Y., Wang, X. M., Huang, M., Sun, X. J., Zhou, Y., and Wang, X. M., Comparison of methods to preserve Rheum palmatum (Polygonaceae) for efficient DNA extraction and PCR amplification, vol. 15, p. -, 2016.

In this study, we compared the quality of DNA extracted using the modified CTAB method, from Rheum palmatum leaves preserved using fourteen different methods, including ones used commonly in other species: under ultra-cold (-80°C) temperatures, after drying with an absorbent paper, desiccating using a silica gel, drying at 60°C, in 70% ethanol, absolute ethanol, 70% ethanol supplemented with 50 mM EDTA, SDS-DNA extracting solution, nuclear separation buffer, improved NaCl-CTAB solution, TE-buffer, I-solution, or II-solution.
