Specific Expression of DR5 Promoter in Rice Roots Using a tCUP Derived Promoter-Reporter System
Figure 4
Construction of DR5::GUS reporter vectors on the basis of A and C configurations.
(A) The synthetic auxin responsive promoter DR5 (267 bp, yellow arrow) was inserted in group A vectors before the GUS reporter to make a1-DR5, a2-DR5 and a3-DR5. (B) A similar strategy was used to construct the DR5 promoter in group C vectors and named c1-DR5, c2-DR5 and c3-DR5 respectively.
