Fig. 7.
The cdkb1;11;2 and cyca2;234 mutants are insensitive to treatment with aminocyclopropane-1-carboxylic acid (ACC) and aminoethoxyvinylglycine (AVG). (A) Abaxial epidermis of cotyledons of the cdkb1;11;2 and cyca2;234 mutants treated with ACC or AVG compared with the control (Mock). The arrows indicate single guard cells (SGCs). Scale bars are 20 μm. (B) Proportion of SGCs in the cdkb1;11;2 and cyca2;234 mutants and the wild-type (WT) treated with either ACC or AVG. Data are means (±SD) (n=10).
