Fig. 2. Tissue distribution of Arabidopsis sphingolipids. (A) Total amount of Cers, hCers, Glcs and GIPCs in seedlings, seeds and oil of Arabidopsis thaliana. Sphingolipid levels are shown according to the nature of LCB moiety (legend in Cers). (B) GIPCs and Glcs profiles in seedlings and seeds. GIPCs and Glcs amounts were shown according to their FA length and hydroxylation and the nature of their LCB moieties. (C) Cers profiles in seedlings, seeds and oil. Cers amount are shown according to FA length and the nature of LCB. The relative distribution of each LCB among Cers in different tissue is also shown.
