Figure 5From: Holdfast spreading and thickening during Caulobacter crescentus attachment to surfacesGrowth of holdfast attached to a surface measured with AFM. (a) and (b) are the diameter and thickness of dried holdfast measured from AFM images as functions of cell age, averaged over 20 holdfasts for each data point. The error bars are standard errors. The dashed lines are drawn as guide to the eye.Back to article page
