Characteristics of green-phase elongation in cells irradiated in G1 phase.

<p>(A) Pedigree analysis in cells irradiated during G1 phase. Rearrangement of cell population irradiated in G1 in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0128090#pone.0128090.g003" target="_blank">Fig 3D</a>, according to the length of red phase (a). Rearrangement of panel a after subtraction of G1-phase duration (b). (B) Quantitative relationship between stage within G1 phase (cell No.) at the time of irradiation and durations of green phase, derived from Fig 4A. Regression line: y = 0.0197x + 11.447, r = 0.372, p < 0.001. (C) Comparison of green-phase duration between cells irradiated in early (red phase duration > 4 h) and late (red phase duration ≤ 4 h) G1 phases, using data from Fig 4A. Data are represented as box-and-whisker plots, as described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0128090#pone.0128090.g003" target="_blank">Fig 3E</a>. For both populations, n = 100. **, p < 0.01 by Mann–Whitney U test. (D) Comparison of red-phase durations between cells with shorter (≤ 13 h) and longer (> 13 h) green-phase durations after irradiation in G1 phase, using data from Fig 4A. Data are represented as box-and-whisker plots, as described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0128090#pone.0128090.g003" target="_blank">Fig 3E</a>. For both populations, n = 100. **, p < 0.01 by Mann–Whitney U test.
