Genes putatively involved in organic matter metabolism and their differential expression under each treatment relative to the control with positive and negative values as described in Table 2.

<p>All values significant at <i>p</i>≤0.05.</p

Dissolved inorganic nitrogen, microcystin levels, and <i>mcy</i> gene expression.

<p>A) Dissolved inorganic nitrogen (DIN) concentrations at the time of harvest, B) microcystin content per cell at the time of harvest and C) the fold change in gene expression relative to the control of microcystin synthetase genes. Bars represent means and error bars represent standard deviation among three biological replicates. Stars indicate significant differences relative to the control (<i>p</i><0.05, Tukey Test).</p

Genes involved in phosphorus metabolism and their differential expression under each treatment relative to the control with positive and negative values as described in Table 2.

<p>All values significant at <i>p</i>≤0.05.</p

Genes involved in nitrogen metabolism and their differential expression under each treatment relative to the control.

<p>Positive values indicate an increase in transcript abundance. Negative values indicate a decrease in transcript abundance. All values significant at <i>p</i>≤0.05.</p

Venn diagram displaying the number of significant differentially expressed genes (<i>p</i>≤0.05) that either increased or decreased in unison in each treatment comparison represented.
