Mapping CW mechanics in populations of mutants defective in cell diameter. (A) Schematic of cell outlines for WT and 3 classes of diameter mutants, with defects in intercellular average radius (i), intercellular variance of the radius (ii), or in intracellular variance of the radius (iii). (B) Midslice confocal image of representative cells corresponding to the classes shown in A. (Scale bars, 2 μm.) (C–E) Mean cell radius on cell sides of different mutants and conditions (C) and SDs (StDev) (D) as annotated in the legend (E). (F–H) Cell radius (R₁), plotted as a function of side wall thickness (hs), side bulk modulus divided by pressure (Ys/P) or side surface modulus divided by pressure (hsYs/P), in the conditions and mutants listed in the legend (E). Each strain is represented by its mean value. The line is a linear fit on mean values. r values are Pearson correlation coefficients.
