Abstract

Unlignified primary cell walls containing ester-linked ferulic acid fluoresce blue in ultraviolet radiation which changes to green with increased intensity on treatment with ammonium hydroxide. Using this fluorescence behaviour, we detected ester-linked ferulic acid in the primary cell walls of all41 species of gymnosperms we examined. These species were in 17 families representing all four extant classes of gymnosperms. In addition, we obtained cell-wall preparations containing > 95% primary cell walls from nine gymnosperm species in nine families, representing all four extant classes. These preparations were analysed for ester-linked monomeric phenolic acids. We found ferulic acid (mostly trans) (88-1,561 mu g/g cell walls) in all of the preparations and p-coumaric acid (mostly trans) (0-106 mu g/g cell walls)in all except one of them. Ferulic acid eater-linked to primary cell wallshas previously been found in angiosperms: in the commelinoid monocotyledons and in the dicotyledon order Caryophyllales, both monophyletic groups. From the present results, we postulate that the extant classes of gymnospermsare monophyletic and no class is sister to the angiosperms. (C) 2000 Elsevier Science Ltd. All rights reserved.
