A modified RNA extraction method was developed for fungal and plant tissues that has several advantages compared with existing, published methods for materials with high contents of ribonuclease, phenolics and polysaccharides. The method uses guanidinium isothiocyanate in the homogenization buffer, and then hexadecyltrimethylammonium bromide (CTAB). soluble polyvinylpyrrolidone and insoluble polyvinylpolypyrrolidone in the extraction buffer. The procedure consistently produced a high yield of relatively high purity, undegraded RNA from a variety of biological materials and should be useful for other tissues where RNases, phenolics and sticky polysaccharides are a problem.
