Additional cells and abnormal cell walls in cross-sections of wild type and rsw2 mutants. Wild type (A), rsw2-3 at 19°C (B), rsw2-3 at 30°C for 24 h (C), rsw2-4 at 30°C for 24 h (D). Scale bars = 25 μm. rsw2-3 shows constitutive changes as well as a temperature sensitive component. Note that the magnification of the wild-type roots is nearly double that of the mutant roots.
