GUS activity in transgenic Arabidopsis plants of pPLAIIIδ::GUS fusions. (A) A seed sprouting after 24 h. (B) 7-day-old seedling (a magnified image of a cross-section of the hypocotyl). (C) 15-day-old seedling (a magnified image of a leaf). (D) 5-week-old plant. (E) pPLAIIIδ expressed in the elongation and meristem zones of the primary root. (F) Cross-section of the primary root. (G) Lateral root at stage VI of lateral root development. (H) Lateral roots emerging from the primary root. (I) Flowers. (J) The gynoecium 48 h after hand-pollination. (K) Cross-section of an immature silique. (L) The mature silique. v, vascular bundles; s, septum; ex, exocarp; m, mesocarp; en, endocarp. Bars =10 μm (E to H, J), 100 μm (A, I, K) or 1 cm (B, C, D and L).
