Abstract
The sphingoid long-chain base (LCB) composition of glucosylceramides was characterized in 31 species of Fabaceae including the model legumes Lotus japonicus and Medicago truncatula. With the exception of Lupinus texensis L, the 8-trans/cis-unsaturated isomers of 4-hydroxy-8-sphingenines [i.e., t18:1 (8t) plus t18:1 (8c)] were the major components in each species. In tribe Fabeae, each species from four genera--Pisum, Lathyrus, Lens, and Vicia--showed that more than 50% of dihydroxy sphingoid LCBs are 8-sphingenines [i.e., d18:1 (8t) plus d18:1 (8c)]. These results suggest that the sphingoid LCB composition of glucosylceramides reflects the phylogenetic relationships within the Fabeae.Entities:
