Functional Analysis of the Subpromoters PR7 and PR2 of the GLDPA1 Gene of F. pringlei.
Regions 1 and 2 (GLDPA-Fp1-2; 641 bp) and 7 (GLDPA-Fp7; 318 bp) of the 5′ flanking region of the GLDPA gene of F. pringlei (C3) were 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.
