Changes in fatty acid composition of major fatty acids in seed lipid during seed development of wild type and a PLDζ. A, Palmitic acid (16:0). B, Stearic acid (18:0). C, Oleic acid (18:1). D, Linoleic acid (18:2). E, Linolenic acid (18:3). F, Eicosenoic acid (20:1; SD, n = 3). Significant differences (T test, P < 0.05) between PLDζ and wild type are denoted with an asterisk.
