Fig. 5From: Organism-environment interactions and differential gene expression patterns among open-coastal and estuarine populations of Porphyra umbilicalis Kützing (Rhodophyta) in the Northwest AtlanticRelative expression patterns of contig NH4-4469 annotated as an AMT under low (< 5 μM NH4+) and high (5 mM NH4+) N conditions for three pieces of tissue cultured neutral spores from algal populations collected at FS, DP, Quoddy Head, and Schoodic Point. Error bars represent the standard error of the mean. Letters denote significance at the Bonferroni-adjusted alpha = 0.017. There was no significant difference in the mean relative expression among populations under high N treatments, and therefore, no letters are given to denote significanceBack to article page
