Spatio-Temporal Labeling of Bacterial Growth (image) Indiana University Share Print E-Mail Caption Spatio-temporal labeling of bacterial growth in the bacterium Streptomyces venezuelae, which grows from the tips of its multiple branches. When the cell is successively exposed to fluorescent D-amino acid probes of different colors, each new probe indicates the location and extent of cell wall synthesis during the respective labeling periods. The final labeling pattern, far right, then provides a chronological account of shifts in cell wall synthesis of individual cells over time.
