Abstract: It is difficult to extract total RNA from strawberry fruits since the fruits are rich in phenols, polysaccharide and other secondary metabolism substances. In order to establish a method for extracting total RNA from strawberry fruits, modified CTAB method and modified EASYspin plant RNA extraction kits methodwere compared. The concentration, integrity and purity of total RNA were detected by the agarose gel electrophoresis and nucleic acid/protein assay (NanoDrop 2000). The results showed that both methods were fit for extracting high-quality RNA from strawberry fruits with two distinct electrophoresis bands of 28S and 18S. Both the OD260/OD230 values and the OD260/OD280 values were 2.0 above. Modified CTAB method was cheap and of high-quality, but modified EASYspin plant RNA extraction kits method was simple, safe and rapid. RTPCR analysis showed that extracted total RNA could be applied to gene cloning and other molecular biology experiments.
