Plant secretes wax suberin
WebApr 19, 2001 · Abstract. Plant cuticle comprises an insoluble lipid‐derived polymeric structural component – cutin – embedded in a complex mixture of soluble lipids (‘wax’). When a plant needs to erect a barrier to seal a wound or to generate an internal diffusion‐resistant compartment, a polymeric cell wall accrustation – suberin – together ... WebThe chemical composition of lipids (waxes) obtained by chloroform extraction, as well as the monomeric composition of native and wound suberin polymer after transesterification by boron trifluoride/methanol, was analyzed using gas chromatography and mass spectrometry. Both types of periderm contained up to 20% extractable lipids.
