Analysis of a Putative Promoter Region within COP1 in lip1 Peas.
The 2.5-kb CPP region located between exon 7′ and exon 1 (see Figure 4) was used to create a transcriptional fusion with the uidA reporter gene and a nos terminator sequence.
(A) GUS actively expressed from a CaMV 35S promoter in onion epidermal cells after microprojectile bombardment.
(B) GUS activity from the CPP region.
(C) GUS histochemical staining after bombardment with a promoterless construct.
(D) GUS activity in a representative 7-day-old transgenic Arabidopsis seedling containing uidA fused to CPP.
