TPK3 and KEA3 GUS reporter gene study in Arabidopsis tissues of different developmental stages. The following genes and stages were examined: pTPK3::GUS and pKEA3::GUS expression in 4-d-old seedlings (A), 11-d-old plants (B and C), rosettes of 19-d-old plants grown on one-half strength MS agar plates (D), mature leaves of 28-d-old plants (E), and flower tissue of 4.5-week-old plants grown in one-half strength MS hydroponics culture (F and G). Bars = 1 mm (A, B and G), 2 mm (C, E and F, left) and 5 mm (D and F, center and right).
