Extended Data Figure 1 : Cell-shape analysis of wild-type and mapZ mutant strains.

From: MapZ marks the division sites and positions FtsZ rings in Streptococcus pneumoniae

Extended Data Figure 1

a, Cell length distribution of wild-type, ΔmapZ, mapZ-2TA, mapZ-2TE, mapZΔcyto, mapZΔextra and mapZΔ(1–41) strains, as well as for ΔmapZ/PZn-mapZ in the presence of 0, 0.1 or 0.2 mM of ZnCl2 inducer. Average cell length (L) and width (W) are given with standard deviations for a total of n cells analysed from three independent experiments. P value < 1.59 × 10−2, two-tailed t distribution determined using a non-parametric statistical test for a critical value of 0.05. b, Phase contrast microscopy and FM4-64 membrane staining imaging of mapZ+ cells (mapZ is restored at the chromosomal locus in ΔmapZ), ΔmapZ/PZn-mapZmapZ cells complemented ectopically with PZn-mapZ), mapZΔcyto and mapZΔextra cells. Images are representative of experiments made in triplicate.
