pas2–1 mutation leads to a general reduction of VLCFA levels. (A) Total fatty acids from pas2–1 and wild-type seeds were transmethylated and quantified by gas chromatography using an internal standard. (B) Cuticular wax loads on stems of wild type (Col0, white bars) and pas2–1 (black bars). Wax load was analyzed according to fatty acid chain length and side group, that is, primary alcohols (24OH, 26OH, 28OH, 30OH), fatty acid (fa C28), alkanes (Alk27, Alk29, Alk31), secondary alcohol (AlcII C29), and ketone (Ket29). (C) Fatty acyl chain length composition of the glucosylceramide (GluCer) fraction from wild type (Col0, white bars) and pas2–1 (black bars). Fatty acid values are the average of three samples ± SD.
