Initial Incorporation of [¹⁴C]Acetate-Labeled Nascent Fatty Acids into Leaf Lipids.

Continuous [¹⁴C]acetate labeling of 3-week-old leaves over a 1-h time course.

(A) Total ¹⁴C accumulation in organic extractable lipids, and linear regression. All data points are average and se from three sets of independently labeled plants. Significant differences (Student’s t test, p-value <0.05) in lipid labeling between lines at each time point are indicated by asterisks above the data points.

(B) and (C) Incorporation of [¹⁴C]acetate into major labeled membrane lipids and DAG in the act1 and act1 lpcat1 lpcat2 lines, respectively. All data points are average and se from three sets of independently labeled plants.
