Extended Data Fig. 8: Influence of ambient O2 on expression of hypoxia-induced RNAs in A. thaliana and S. habrochaites accessions.
From: An oxygen-sensing mechanism for angiosperm adaptation to altitude
a, Pchlide in A. thaliana high-altitude accession Sha, and erfVII (pentuple mutant obtained from the low altitude accession Col-0), measured at 48 m a.s.l. (SB, pO2 21.2 kPa) and 2479 m a.s.l. (ESPE, pO2 15.7 kPa). b, PORA/B, CHLM gene expression in A. thaliana accessions collected at different altitudes measured at 48 m a.s.l. (pO2 21.2 kPa, SB) or at 2479 m a.s.l. (pO2 15.7 kPa, ESPE). c, Hypoxia-related gene expression in A. thaliana accessions Col-0 (low altitude) and Sha (high altitude), at 48 m a.s.l. in different ambient levels of oxygen. d, Expression of S. habrochaites hypoxia-related genes at 15% and 21% ambient oxygen in accessions from different altitudes measured at 48 m a.s.l. Carried out using etiolated seedlings after 5 days growth (48 m a.s.l). Means are plotted, error bars report SD, coefficient of determination (R2) is given. For each n = 3 biologically independent experiments. For a, Sha (SB) was measured once.
