PCho, Cho, and PtdCho Determination in xpl1 and Wild-Type Plants (nmol g⁻¹ Fresh Weight)

Molecule	Col 0 Roots	xpl1 Roots	Col 0 Leaves	xpl1 Leaves
PCho	14.6 ± 1.0a	13.6 ± 0.7a	54.0 ± 2.0b	50.1 ± 1.5b
Cho	41.7 ± 2.0a	35.6 ± 2.5a	63.5 ± 2.5b	59.8 ± 3.0b
PtdCho	114.9 ± 3.9a	89.5 ± 3.5b	115.3 ± 7.8a	94.7 ± 5.2b

Data are means and se (±) for three independent assays and were statistically analyzed in the SPSS 10 program (SPSS, Chicago, IL). Duncan's method was used to determine whether the differences between mutant and wild-type plants were statistically significant with a 95% confidence coefficient. The univariate analysis showed significant differences in the content of PtdCho between Col 0 and xpl1 tissues by grouping values in distinct subsets (a or b).
