Leaf size in Arabidopsis ATHCK2A1 antisense transformants. A, Measurement of juvenile leaves of the wild-type (WT) and antisense transformants (D, F, G, H, and M). B, Measurement of adult leaves of the wild type and antisense transformants taken from 21-d-old plants grown under continuous white light. Data are means of more than 15 plants of each line. Error bars show +sd of measurements. C, Schematic representation of the lower part of an Arabidopsis plant. A cauline leaf (cross-hatched) between the floral stem (FS) and the secondary inflorescence stem (SIS) was taken as an adult leaf. Juvenile leaves (striped) were taken from the rosette (R). PIS, Primary inflorescence stem. The leaves from plants transformed with the plasmid vector only were indistinguishable from wild-type leaves with regard to size.
