WAK4 Antisense Expression Results in Dwarf and Sterile Phenotypes.

(A) DEX-treated W4A plants appear to be dwarfed and have vertically grown leaves.

(B) DEX-treated W4A plants have smaller, unopened flowers (+) compared with those of the wild-type control (−).

(C) DEX-treated W4A plants have shortened siliques and pedicels (+) compared with those of the control wild-type plants (−). Siliques from the DEX-treated W4A plants (+) yield no viable seed.

(D) DEX-treated W4A plants yield shorter inflorescence stems and silique pedicels (+) compared with those of the wild-type control (−).
