Longitudinal sections of the shoot apex) from wild-type control (A) and bhlh093-1/bhlh061 double mutant (B and C) note the region of thickening growth below the meristem. Wild-type control (D) and bhlh093-1/bhlh061 double mutant (E) at 60 d post-germination. Note the cavity (arrow pointing toward it) located in the region beneath the SAM in the double mutant.
