Improvement of Polyunsaturated Fatty Acid Production in Echium acanthocarpum Transformed Hairy Root Cultures by Application of Different Abiotic Stress Conditions

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.
