Composition of the Aliphatic Components of Suberin of the Endodermal Fraction from the First Internode of Etiolated Sorghum Seedlings 1

The stems from etiolated seedlings of Sorghum bicolor were separated into epidermal and endodermal fractions by manually removing the stele from the cortex. The epidermal fraction was shown to contain a lipid polymer whose monomeric composition was characteristic of cutin with dihydroxyhexadecanoic acid as a major component (25%). The endodermal fraction contained a lipid polymer whose monomeric composition was characteristic of suberin: hexadecanoic acid 12%, octadecenol 6%, octadecenoic acid 23%, {omega}-hydroxyhexadecanoic acid 17%, hexadecanedioc acid 8%, {omega}-hydroxyoctadecenoic acid 8%, and octadecenedioic acid 12%. This endodermal polymer is thought to be the suberin component of the Casparian band.
