Phenotype of the node in <i>brm-3</i>, <i>bp-9</i>, and <i>brm-3 bp-9</i> mutants.

<p>(A) <i>brm-3 bp-9</i> showed obvious bend at node (bar = 0.5cm). (B) Quantitative analysis of the angles at the node in Col, <i>brm-3</i>, <i>bp-9</i>, and <i>brm-3 bp-9</i> plants. 50 plants were analyzed. (C) <i>brm-3 bp-9</i> displayed chlorenchyma-deficient (as indicated with red arrow) in the stem (bar = 0.5cm). (D) Transverse section of the stem at the nodes of the wild type and mutants. Arrows indicate the regions in which chlorenchyma development is repressed (bar = 2000 μm).
