Decreased fitness correlates with altered cell cycle progression.

<p>The y-axis shows the fitness values of Giaever et al <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1002590#pgen.1002590-Giaever1" target="_blank">[33]</a>. Higher values indicate reduced fitness. The cutoff for reduced fitness was about <85% of the wild type in that study <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1002590#pgen.1002590-Giaever1" target="_blank">[33]</a>. Thus, strains with possible small reductions in fitness have been assigned a “WT-like” fitness score of 1. Giaever et al <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1002590#pgen.1002590-Giaever1" target="_blank">[33]</a> evaluated fitness of the same strains we used, during growth in rich (YPD-2%Dextrose) liquid media, allowing for a direct comparison with our dataset. We used the non-parametric Spearman test to obtain the correlation (<i>r</i>) values we show. The correlation coefficient for all the strains (<i>r</i>_T) is shown at the bottom right of the graph. We colored the r values for the sub-groups as in <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1002590#pgen-1002590-g002" target="_blank">Figure 2</a>. For every gene we included in this analysis, the values we used in this correlation are shown in <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1002590#pgen.1002590.s001" target="_blank">Dataset S1</a>.
