This is our latest data [download data]. In this paper, we provide the most complete single-cell growth and the cell cycle data in both E. coli and B. subtilis as we managed to track not only the division cycles but also the replication cycles. The original reference is
More recently, JT Sauls in our lab obtrained extensive B. subtilis single-cell data for both growth and the cell cycle. The data can be downloaded from the following:
The data from the following two papers are typically cell size prameters vs. time of a large number of individual cells for many generations. Segmentation and lineage information is also included.
In the original 'mother machine' paper in 2010, we also included the YFP level information. If you want to revist the adder principle, we recommend the 2014/2015 data as we took particular care to carefully calibrate the threshold for cell size.

*We reported the discovery of the adder principle in this paper.
This project took enormous time and resources. Using an automated multiplex turbidostat, we explored hundreds of different growth conditions in E. coli and measured
1. growth rate
2. cell size
3. cell shape
4. cell cycle ("C+D" period)
5. RNA/protein ratio
The types of perturbations include
a. nutrient limitations
b. translational inhibitions
c. transcriptional inhibitions
d. DNA replication speed
e. replication initiation
f. cell shape
g. lipid synthesis
h. cell-wall synthesis
We often used orthogonal approaches (genetic and pharmacological) for each type of perturbation. For example, for 'd. replication speed', we used three different approaches: tCRISPRi on elongation machinery, hydroxyurea, and thymine limitations. The original reference is
We've put up our plasmids on Addgene for anyone to get. These strains include
