Differentially expressed P. patens genes involved in photochemical reactions of photosynthesis in response to elevated CO2 (1500 ppmV), sub-ambient O2 (13%), and low O2–high CO2. (A) Heat map of the significantly expressed transcripts of photosynthesis based on MapMan functional classification. (B) Venn diagram showing overlapping transcripts that are significantly down-regulated in P. patens gametophytes exposed to elevated CO2, sub-ambient O2, or low O2–high CO2 treatment. (C) Venn diagram showing overlapping transcripts that are significantly up-regulated in P. patens gametophytes exposed to elevated CO2, sub-ambient O2, or low O2–high CO2 treatment.
