Individual and combined effects of altering WRI1, DGAT1, and SDP1 expression on seed percentage oil content (A), average seed mass (B), seed yield (C), seed number (D), and oil yield (E). Values are means ± se of measurements on seeds from individual plants (n = 12) of each genotype grown in controlled conditions. Asterisks denote statistically significant differences from the wild type (lsd test), where significant differences between genotypes were detected (F test). C is the wild type, E is an empty vector control, and W, D, and S are independent homozygous lines expressing the WRI1, DGAT1, and RNAi SDP1 transgenes individually and in combination.
