Table II. Leaf metabolite profiling of wild-type and LPLA RNAi plants

Values are presented as nmol g−1 fresh weight (means ± se from four individual plants). Values in boldface are significantly different from wild-type values according to a two-tailed Student’s t test (P < 0.05). n.d., Not determined.
