| Abstract: | Objective] To determine the rapid DNA extraction method from calli or leaves of Aquilaria sinensis.Method] We tested three methods （TE,ES1,ES2） used in Arabidopsis and rice for rapid DNA extraction from leaves and calli ofA.sinensis.The extracted products were evaluated through agarose gel electrophoresis,PCR and real-time PCR reactions.The amplicons were further confirmed by clone and sequencing.Result] The extraction method using solution ES1 could successfully isolate total DNA from leaves and calli ofA.sinensis in 20 min：agarose gel electrophoresis showed clear binds.The DNA was qualified for PCR amplification of ～ 200 bp or ～ 600 bp sequences.The extracted product from calli using solution ES2 can also amplify the ～ 200 bp sequence,but failed to amplify the ～600 bp sequence.Other methods were failed to extract DNA and amplify any sequences.Conclusion] The method using ES1 solution is qualified for rapid DNA isolation from A.sinensis for PCR amplification,which will lay a foundation for Aquilaria plants germplasm and molecular research. |
