COX11:GUS promoter analysis. Plants from three COX11:GUS lines (T2 generation) were assayed for GUS activity at various developmental stages by bright-field microscopy. Representative staining patterns are shown. (A) Embryos after overnight imbibition and removal of the seed coats. (B) A 3-day-old seedling. (C) Mature leaf. (D) Arabidopsis flower. (E) Anthers with mature pollen. (F) Two images of different parts of a 12-day-old seedling, stitched together. The insert panels show a section of its cotyledon (G) and a lateral root primordium (H) at a higher magnification. (I) Germinated pollen. (J) Pollen grain rehydrated in 18% sucrose. (K) Siliques at different developmental stages.
