Values (mol %) of three independent samples were averaged and the sd is indicated. Plants were grown on soil for 4 weeks. PtdIns, phosphatidylinositol.
a
Values are significantly different from wild-type values based on Student's t test (95% confidence interval).
b
This lipid sample also contains TGDG at <1 mol %.
