Critical regulatory element HDZIP2ATATHB2 was determined by GUS assays in stably transformed Arabidopsis plants. A, Localization of PGbPDF1-1::GUS (a–c) and PGbPDF1-2::GUS (d–f) in transformed Arabidopsis. Both of the promoters could drive GUS expression in 5-d-old seedlings (a and d), leaves (b and e), and inflorescences (c and f). B, The GUS activity in the inflorescences and siliques of the transformed Arabidopsis plants was abolished once region B or the regulatory element HDZIP2ATATHB2 (AT9) was deleted in the sequence of PGbPDF1-1.
