In soybean (Glycine max (L.) Merr.) root nodules the level of hydroxyproline-containing molecules is developmentally regulated. Hydroxyproline accumulates in both nodule cortex and medulla. In the cortex, the hydroxyproline is mainly localized in the cell wall, presumably as extensin, but in the medulla it is mainly in the soluble fraction as an arabinogalactan protein (AGP). Nodule-specific AGPs are present at early nodulation. The highest concentration of AGP is in the nodule medulla, followed by nodule cortex, uninfected roots, leaves, flowers, pods and seeds. Root nodules and all organs of the soybean plant that were tested were found to express a tissue-specific set of arabinogalactan proteins.
