Diagram of Arabidopsis stomatal development (left; based on Pillitteri and Torii [2012]) and the respective TET2 expression patterns at the abaxial epidermis of 6-d-old cotyledons of the pAtTET2::NLS-GFP/GUS line (right). A, TET2 expression in the meristemoid after entry division. B and C, TET2 expression in the meristemoid after one or two additional asymmetric divisions. The arrow indicates the meristemoid. D and E, TET2 expression in the guard mother cell and the mature guard cells, respectively. Cells in different colors are as follows: meristemoid mother cell, gray; meristemoid, blue; stomatal lineage ground cell, white; guard mother cell, red; guard cell, green; pavement cell, light green. Bars = 0.01 mm.
