Phenotypic characterization of <i>Synechocystis</i> sp. PCC 6803 substrains reveals differences in sensitivity to abiotic stress - Fig 5

<p>Growth rates of <i>Synechocystis</i> sp. PCC 6803 substrains GT-L (white circles), GT-B (red triangles) and PCC-B (blue squares) under temperatures 23°C—38°C during cultivation in a quasi-continuous regime (A) and after introduction of heat shock of 52°C (B) and 60°C (C) during the batch growth. A–The Q<sub>10</sub> coefficient was calculated according to [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0189130#pone.0189130.ref019" target="_blank">19</a>], the dashed lines represent linear fitting of the data points by the least squares method in the temperature range 23°C—32°C (23°C—35°C in case of the substrain GT-B). Each point represents average of at least four independent experiments, error bars represent standard errors. B, C—Batch growth was performed at 32°C and the heat shock was introduced by increasing temperature for four hours after the cultures reached OD<sub>680</sub> 0.7 (the temperature record is marked by dashed line). The batch experiments were performed at least in three biological replicates with quantitatively similar results, data from one representative experiment are shown.</p>
