Fig. 4. — Fatty acid concentrations in Arabidopsis thaliana (Col-0) exposed to a combination of elevated heat and drought at ambient and elevated CO₂. (a) Dodecanoic (C12:0), (b) tetradecanoic (C14:0), (c) pentadecanoic (C15:0), (d) hexadecanoic (C16:0), (e) hexadecenoic (C16:1), (f) hexadecadienoic (C16:2), (g) hexadecatrienoic (C16:3), (h) heptadecanoic (C17:0), (i) octadecanoic (C18:0), (j) octadecenoic (18:1), (k) octadecadienoic (C18:2), (l) octadecatrienoic (C18:3), (m) eicosanoic (C20:0), (n) eicosadienoic (C20:2), (o) docosanoic (C22:0), (p) tricosanoic (C23:0), (q) tetracosanoic (C24:0), (r) tetracosenoic (C24:1), (s) pentacosanoic (C25:0), (t) hexacosanoic (26:0), (u) total lipids, and (v) double-bond index (DBI). Data are means (±SE) (n=5). Treatments: C, ambient CO₂, i.e. control; CO₂, control plus elevated CO₂; HD, combined heat and drought at ambient CO₂; HD + CO₂, combined heat and drought at elevated CO₂. The shading on the bottom axes corresponds to the treatments as shown in Fig. 1.
