Exploring Phylogenetic Relationships between Hundreds of Plant Fatty Acids Synthesized by Thousands of Plants. more details ...
Abstract The seed oil of 14 Boraginaceae species was surveyed in a search for new sources of γ-linolenic acid (GLA, 18:3ω6). GLA content on total fatty acids ranges from the absence in Cordia and Halgania species to 23.9% in Lithospermum latifolium. The percentage of GLA on total seed weight reaches 3.9% in L. latifolium and Pulmonaria officinalis. The relatively high GLA percentage for Echium russicum suggest a distant taxonomic relationship when compared to other continental Echium. © 2003 Elsevier Science B.V. All rights reserved.
