Fatty Acids Production from Plants and Callus Cultures of Cereus peruvianus Mill. (Cactaceae)

摘要

Callus culture of Cereus peruvianus provides an alternative method to unsaturated and unusual fatty acid s production. Analysis of fatty acid s composition of the lipids extracted from hypocotyls-induced calli showed that linoleic acid (C_18:2) was the major component of unsaturated fatty acid s in the callus culture. Unusual fatty acid s such as pentadecenoic acid (C_15:1), palmitolenic acid (C_16:1) and heptadecanoic acid (C_17:0) were also detected in callus tissues. The long-time callus culture of C. peruvianus is a good model for the biochemistry studies of C_18:2 rich tissues, for unusual fatty acid production and for metabolic engineering of plants.
