Functional Analysis of the 5′ Flanking Sequence of a Group B GLDP Gene of the C₃ Species F. pringlei.

The 5′ flanking sequence of GLDPB2-Fp (2733 bp) as a representative of group B GLDP genes of C₃ Flaveria was fused to the GUS reporter gene and analyzed in transgenic F. bidentis (C₄) and transgenic Arabidopsis (C₃).

(A) Histochemical localization of GUS activity in leaf sections of transgenic plants.

(B) GUS activities in leaves of transgenic plants. Each dot indicates an independent transgenic line. The black line represents the median. MU, 4-methylumbelliferone.
