The Isolation of DNA from Plant Materials

Lin Zhong-ping, Liu Hong-jun, Wu Shi-jun, Ma Cheng, Zhao Yu-jin and Wang Yu-xiu   

Abstract: Total DNA was isolated from seedling and tissues of many plants. The nuclei and chloroplasts were prepared from plant tissues, and then the nuclear DNA and chloroplast DNA were isolated from them. According to the chemical analysis and the physical properties determined by ultraviolet absorbance, hyperchromicities, ultracentrifugation, gel electrophoresis and the electro-microscopical observations it is suggested that DNA obtained possessed a considerable purity and to a certain extent retained the natural status of the large molecule.
