Pearson correlation analysis between gene expression levels of lipid metabolism genes and the amounts of single FAs of the NL, GL, and PL fraction of A. alpina perpetual flowering 1‐1 (pep1‐1) mutant lateral stem internodes of perennial (PZ) and annual (AZ) zones. The analysis was performed between stages III_PZ, IV_PZ, and I′, II′ for PZ and IV_AZ_if and II′ for AZ (see Figures 1 and 5a). (a) Correlation analysis between NL‐derived FAs and NL metabolism‐related genes. DSEL, DAD1‐LIKE SEEDLING ESTABLISHMENT‐RELATED LIPASE, Hb2, HAEMOGLOBIN 2, LPCAT1, LYSOPHOSPHATIDYLCHOLINE ACYLTRANSFERASE 1, PES1, PHYTYL ESTER SYNTHASE 1, SDP1, SUGAR‐DEPENDENT1, WRI1, WRINKLED 1. (b) Correlation analysis between GL‐derived FAs and GL metabolism‐related genes. DALL3, DAD1‐LIKE LIPASE 3, DGD1, DIGALACTOSYL DIACYLGLYCEROL DEFICIENT 1, PLDζ2, PHOSPHOLIPASE D ζ 2, PLIP3, PLASTID LIPASE 3, pPLAIIIβ, PATATIN‐RELATED PHOSPHOLIPASE A IIIβ. (c) Correlation analysis between PL‐derived FAs and PL metabolism‐related genes. ACT1, ACYLTRANSFERASE 1, GPAT3, GLYCEROL‐3‐PHOSPHATE SN‐2‐ACYLTRANSFERASE 3, GPAT4, GLYCEROL‐3‐PHOSPHATE SN‐2‐ACYLTRANSFERASE 4, GPAT8, GLYCEROL‐3‐PHOSPHATE SN‐2‐ACYLTRANSFERASE 8, GPDHP, GLYCEROL‐3‐PHOSPHATE DEHYDROGENASE PLASTIDIC, LPAT1, LYSOPHOSPHATIDIC ACID ACYLTRANSFERASE 1, LPAT3, LYSOPHOSPHATIDYL ACYLTRANSFERASE 3, LPEAT1, LYSOPHOSPHATIDYLETHANOLAMINE ACYLTRANSFERASE 1. Only correlation coefficients with significant levels of correlation (p < .05) are displayed in the diagrams. Candidate genes differentially regulated between PZ and AZ are represented in red
