Resumo: | An efficient and rapid DNA minipreparation modified method for frozen samples was developed for five tropical tree species: Copaifera langsdorffii, Hymenaea courbaril, Eugenia uniflora, Tabebuia roseo alba and Cariniana estrellensis. This procedure that dispenses the use of liquid nitrogen, phenol and the addition of proteinase K, is an adaptation of the CTAB-based DNA extraction method. The modifications included the use of PVP to eliminate the polyphenols, only one chloroform-isoamyl alcohol step and the addition of RNase immediately after extraction with chloroform. The yields of the DNA samples ranged from 25.7 to 42.1 µg from 100 mg leaf tissue. The DNA samples extracted by this method were successfully used for PCR (SSR and RAPD) analyses in these five and other twelve tropical tree species.
