pPLAIIIδ promotes the accumulation of 20C-containing TAG species. A, Normalized mass spectra (as a percentage of the total) from TAG species with the indicated fatty acyl combinations in wild-type, KO, and OE seeds. The fatty acids making up each molecular species are indicated, but no positional specificity is implied. The TAG species shown on the left side of the dashed lines contain only 16- and 18-carbon chains, while those on the right include one or more 20-carbon chains. Values are means ± se (n = 5). HSignificantly higher and Lsignificantly lower, each at P < 0.05 compared with the wild type, based on Student’s t test. B, Normalized mass spectra (as a percentage of the wild type) from TAGs, grouped by total acyl carbons, were classified as C50, C52, C54, C56, C58, and C60. The major components in C50, C52, and C54 are 18C fatty acyl-containing TAGs, while C56, C58, and C60 are TAGs containing one or more 20C fatty acyl-containing TAGs. Values are means ± se (n = 5). HSignificantly higher and Lsignificantly lower, each at P < 0.05 compared with the wild type, based on Student’s t test.
