Figure 5. Glycerolipid classes in soybean root hairs and stripped roots with and without P_i supply.

Lipids were extracted from stripped roots and root hairs collected from 7-day-old seedlings grown on modified Murashige and Skoog agar medium with 1 mM P_i or no P_i. Glycerolipid amounts are expressed as normalized mass spectral signal/total normalized glycerolipid mass spectral signal (to produce percentage of normalized MS signal, mol% of total lipids). The values are the mean ± SD (n = 10). The data of soybean stripped roots and root hairs were compared via t test and the P < 0.05 is indicated by *, indicating a significant difference. The value for P_i-sufficient seedlings is higher (represented as H) or lower (represented as L) than the value for P_i-deficient seedlings.
