Mutation of mekk1 causes a dwarf phenotype. A, Location of T-DNA insertions. Thick lines are exons. Thin lines are introns and untranslated regions. B, Twelve-day-old homozygous mekk1-1 and mekk1-2 plants grown at 24°C are indicated by arrows. Larger plants are wild-type Col-0. Bar = 1 cm. C, Twelve-day-old plants grown at 24°C on agar plates. Bar = 0.5 cm. D, Environmental scanning electron microscope images of primary leaf epidermis of 10-d-old plants grown at 24°C. Bar = 50 μm. E, RT-PCR of mekk1-1 and mekk1-2 plants. PCR primer locations indicated by arrowheads in A. Actin gene Act2 used as a control. F, Plants grown on soil for 3 weeks at 32°C. Bar = 1 cm.
