Table 3.
Principal components (PC1, PC2) of the studied lipid classes in Echium acanthocarpum E1.5 cell line hairy roots, growing in different culture media at 15°C (C1–C4). Factor loadings and communalities are shown.
| Components matrix | Components | Communalities | |
|---|---|---|---|
| PC1 (65.91%) | PC2 (19.78%) | Extraction | |
| PC | 0.886 | −0.339 | 0.900 |
| PS + PI | 0.759 | 0.094 | 0.585 |
| PG | 0.033 | 0.966 | 0.934 |
| PE | 0.767 | 0.382 | 0.735 |
| Polar lipid | 0.846 | 0.510 | 0.975 |
| Neutral lipid | −0.715 | −0.582 | 0.850 |
Factor loading of the variable (correlations) with PC1 are shown in bold, and those correlated with PC2 are shown in italic.
PC: phosphatidylcholine; PS + PI: phosphatidylserine and phosphatidylinositol; PG: phosphatidylglycerol; PE: phosphatidylethanolamine.
Rotation method: Varimax with Kaiser.
