Biophysics and Computational Biology and Evolution Correction for “Substrate geometry affects population dynamics in a bacterial biofilm,” by Witold Postek, Klaudia Staśkiewicz, Elin Lilja, Bartłomiej Wacław, which published April 15, 2024; 10.1073/pnas.2315361121 (Proc. Natl. Acad. Sci. U.S.A. 121, e2315361121).
The authors note that Fig. 2 appeared incorrectly. Panel E was erroneously duplicated. These images are for illustration purposes only; the main results presented in panels B–D have not been affected. The corrected figure and its legend appear below. The online version has been corrected.
Fig. 2.
Velocity field in the wells. (A) Examples of the velocity field (arrows) and growth rate (color map) for wells of different types. (B) Average vertical velocity (red curve) as a function of distance d from the bottom surface of flat-bottomed wells (n = 11), for an 18 h old biofilm. The individual black lines represent velocities measured at various horizontal positions (approx. 10 per well) within the well, for 11 wells. (C) Growth rate versus distance d from the bottom, for the same data in panel C. Error bars = SEM. (D) Average horizontal component of the velocity field (red curve) versus d. The black lines are as in panel B. (E) Zoomed-in plots of the velocity field near the bottom for a corrugated- and a flat-bottom well. Arrows are color-coded based on the vx/v component of the field (scale bar).
