摘要：

A novel group of cyclopentenone prostaglandin-like compounds, deoxy phytoprostanes J(1), together with their precursors, phytoprostanes D-1, were identified in tobacco, tomato and Arabidopsis. Previously, it was thought that 13,14-dehydro-12-oxo-phytodienoic acid, a member of the deoxy phytoprostanes J(1), family, is derived from either 12-oxo-phytodienoic acid or diketols via the allene oxide synthase pathway. Results suggest that 13,14-dehydro-12-oxo-phytodienoic acid as well as structurally related cyclopentenones of the chromomoric acid family are synthesized via the phytoprostane D-1 pathway in planta. Notably, 13,14-dehydro12-oxo-phytodienoic acid is more abundant than 12-oxo-phytodienoic acid in all three species so far analyzed. (C) 2003 Elsevier Science Ltd. All rights reserved.
