Fig. 1. Vegitative leaf-specific expression of the HBP-1a(17) promoter/GUS fusion gene in transgenic Arabidopsis during development.
The spacial and temporal expression pattern of the cheimeric gene was analyzed by histochemical assays for GUS expression. A, Three-day-old seeding; B, Seven-day-old seeding; C, Eight-day-old seeding; D, Floral organ (mature flower); E, Stem, cauline leaf and axillary bud; F, Plant grown in the dark for a week after growing in light for a week.
