dragon blood
2.The study is based on the materials which are induced by inducer and non-induced from the Dracaena cambodiana seedlings in tissue culture. The study is initiated by construction a subtraction cDNA library of genes related to dragon’s blood biosynthesis from Dracaena draco Linn. by using suppressive subtractive hybridization (SSH) methodology, then 431 recombinants are got by screening the subtraction cDNA library with PCR.
