On the base of review the research development in tissue culture and genetic transformation, Comparative analyses were made on the callus induction and embryogenetic abilities of anther and non-pollinated ovules of rubber tree. Fluorescence detection was implemented with the different in vitro material of Hevea brasiliensis.

However, the mutation of GATA site at -2948bp remarkably reduced the reporter gene activity driven by SV40 promoter, but not by ε-globin gene proximal promoter. To test whether those sites act synergistically, we mutated 2 of these three binding sites with different combinations.
