Fig. 8. Wild-type inflorescences (A) remain relatively straight during bolting. Inflorescences from cap1 mutants exhibit curls and kinks at nodes (B). Some young inflorescences perform almost a complete rotation during early expansion. Pedicles supporting flowers or growing siliques are also curled. The root systems of wild-type plants (C) grown on the surface of solidified agar medium extend radially. Root systems of cap1 plants (D) fail to efficiently colonise the agar surface. Comparison of an individual wild-type root and associated lateral roots (E) with a cap1 root and its associated laterals (F) shows that cap1 roots are excessively curled and looped. Bars, 2 mm.
