(B) Frequency distribution of mRuby expression calculated from experimental data in (A). (C) Cells with a narrow range of GFP-GAVPO exhibit a bimodal or multimodal mRuby distribution. Cells from (A) were divided into 20 equal populations in ascending order of GFP intensities, and graphs of mRuby distribution were calculated from subpopulations 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, and 20 (from bottom to top). (D) Experimental mean mRuby versus mean GFP-GAVPO plotted for the 20 subpopulations (open red circles) closely corresponded to a shallow Hill function (dashed red line) with a Hill coefficient of 1.87 and an ‘EC50’ greater than 108. (E–F) The empirical function (D) predicted a unimodal mRuby distribution for the entire cell population (E) or for subpopulations with narrow GFP-GAVPO ranges (F). (G–I) Hypothetical high cooperativity (G) predicted a bimodal mRuby distribution for the entire cell population (H), but unimodal distributions for subpopulations with narrow GFP-GAVPO ranges (I).

(B) Raw traces of single-cell GFP-GAVPO dynamics. (C) A raw trace of GFP fluorescence (dotted green line) was used to calculate a denominator curve (dotted blue line) that shows the cell cycle of each cell. The sharp drop in single-cell GFP indicates a cell division event, with the denominator values immediately before and after it set to 2 and 1, and connected with linear functions. Raw GFP (dotted green line) or mRuby (dotted red line) signals were converted to normalized GFP (solid green line) or normalized mRuby (solid red line) by dividing by the denominator (dotted blue line).

Cells in the high mRuby expression state are shown in orange. The video shows that the mRuby expression state is mostly inherent in both daughter cells after each division. An example in which two daughter cells took different states is shown near the top at around 30 hr.

Emulation of combinations of ‘high’ states at multiple sites.

Emulated combinations of ‘high’ states at nine sites of 5xUAS-mRuby insertion at incremental light intensities. The emulated combinations were generated using the following steps: (1) we assume that the means and distributions of mRuby expression are identical for each site for the sake of simplification; (2) the mRuby distribution of the ‘high’ state of a single site was mimicked with the mRuby distribution with lowest CV (0.47) and 1/9th of the highest mean expression (300,000); (3) the mRuby distribution of the ‘low’ state of a single site was mimicked with the mRuby distribution of the dark control; (4) each of the inserted sites was randomly designated as ‘high’ or ‘low’ state for 100,000 cells, with the probabilities correlated with light intensities; (5) the combined mRuby distribution was emulated by random sampling of the ‘high’ or ‘low’ states of nine sites for 100,000 cells per light intensity. Cells that were between the ‘high’ and ‘low’ states were not considered in this emulation.

Single-cell ATAC-seq analysis of dynamic noise reductions for HeLa-AB1 cells with PWM.

(A) A dynamic PWM induction program was used to generate cells for single-cell ATAC-seq. As indicated with blue arrows, six cell populations were collected: first at dark control (0 min), and then after one light-on cycle (150 min), after one light-on-off cycle (600 min), after one light-on-off cycle and one light-on cycle (750 min), after two light-on-off cycles (1200 min), and after two light-on-off cycles and one light-on cycle (1350 min). (B) The average number of ATAC-seq reads from a single cell plotted against distance from the transcription start site (TSS) of the 5xUAS promoter for the six populations. (C) Heatmap plots of single-cell ATAC-seq reads from −200 to 200 bp around the TSS of the 5xUAS promoter. Reads are displayed in common logarithms. The counts were added to 0.1 before the logarithm conversion. The x-axis represents the distance from the TSS. The y-axis represents the cell index. Color represents the common logarithm of the reads. There are 384 cells for each time point. (D–E) For each cell, a read was further defined as the average over the 400 bp sequence.
