Table 1.
Composition of the fatty acids of the chloroplast membranes isolated from the barley wild-type Delisa and its 522DK mutant cultured at 20 °C, 5 °C, and 27 °C. Any significant differences between Delisa and the mutant (Student’s t-test, p ≤ 0.05) for each temperature are indicated by different letters. <LOD—below limit of detection.
