Table I. Quantitative analysis of the relative percentage of lipid bands on the TLC plates (Fig. 8A) using ImageJ (http://rsb.info.nih.gov/ij/index.html) software.

The data are means ± sd (n = 3). Asterisks indicate the significance of differences between wild-type and ltn1 mutant plants under the same growth conditions as determined by Student’s t test: * 0.01 ≤ P < 0.05, ** P < 0.01.
