Differentially expressed genes in response to 25 kPa, 25 kPa/NormOx, and 97 kPa/HypOx in roots and shoots of 10 d plants. (A) Heat map of 372 differentially expressed genes with statistical significance (p < 0.01) by at least 2-fold in at least one of responses to 25 kPa, 25 kPa/NormOx (25 kPa/pO₂ = 21 kPa), and 97 kPa/HypOx (97 kPa/pO₂ = 5 kPa) in roots or shoots. Filled colors represent Log2 fold-change. (B) Venn diagram showing the overlap of significantly changed genes (Log2 fold-change >1, p < 0.01) between response to 25 kPa, 25 kPa/NormOx, and 97 kPa/HypOx in roots and shoots. (C) 25 kPa atmosphere associated genes of 10 d plants with biggest difference in expression level between responses to 25 kPa and 25 kPa/NormOx as well as responses to 25 kPa and 97 kPa/HypOx. The genes with difference more than 1.8-fold in roots and shoots were listed. These genes were categorized as “enhanced,” “repressed,” and “Intermediate” according to expression difference.
