AqTFL1 and AqAGL24.2 in situ expression patterns. AqTFL1 expression in four-week (A) and six-week (B, C) vernalized apices. AqAGL24.2 expression in six-week (D, E) vernalized apices and in a higher order post vernalized inflorescence (F). Ap = apical meristem, Ax = axillary meristem, Lax = leaf axillary meristem, lf = leaf, b = bract, sp = sepal, open arrowheads indicate petal and stamen primordia, arrows indicate AqAGL24 expression in leaves. Scale bar = 100 μm A-C; 50 μm D-F.
