CES-GUS expression is present in all organs and is developmentally regulated. A homozygous line expressing a CES-promoter GUS fusion that showed a characteristic staining pattern was chosen for histochemical analysis of CES_pro:GUS expression in different organs and developmental stages. (A, B) Dark-grown seedlings 2 DAG and (C) 10 DAG. (D) Light-grown seedling 3 DAG. (E) Root of a light-grown seedling 3 DAG. (F) Shoot of a 14-day-old plant; the arrow indicates a leaf axillary meristem. (G) Leaf of an adult plant. (H–J) Buds and flowers at stages 9–12 (as defined by Smyth et al (1990)).
