Fatty acids in thylakoid membranes from ΔKS and AC mutant cells grown at different temperatures.

Cells were grown at the indicated temperature for three days. Total lipids were extracted from thylakoid membranes and fatty acids were analyzed as described in Materials and Methods. The double-bond index (DBI) is the sum of percentages of unsaturated fatty acids multiplied by total number of double bonds. The values are the means of three independent experiments and are expressed as mol %. The deviation of values was within ± 2%.
atr. Trace amount (less than 0.2%).
b-. Non-detected.
