GUS expression under the LTPG1 promoter in transgenic Arabidopsis plants. The LTPG1 promoter∷GUS construct was transformed into Arabidopsis plants, and five independent transgenic lines were then stained with 1 mm 5-bromo-4-chloro-3-indolyl-β-d-glucuronide. A, Ten-day-old seedling. High magnification of the root tip (inset 1) and initiation site of lateral roots (inset 2) are indicated by arrows. B, Two-week-old leaf. High magnification of a trichome (inset 1) is indicated by the arrow. C, Cross-section of a leaf. D, Stem. E, Cross-section of a stem. F, Flower. G, Carpel. H, Stamen. I, Petal. J, Sepal. K, Silique wall and developing seeds.
