The presence of rhamnogalacturonan II in this structure is thought to mark a major evolutionary shift, while Peter Albersheim investigated the biological impact of the presence of oligogalacturonans in this structure.

The EXPA and EXPB genes code for proteins that reside in this structure, one of whose components is attacked by EPG. Xyloglucan also plays a major role in this structure. It is made up partly of pectins, which are particularly prevalent in the middle lamella. The apoplast lies immediately inside of it. This structure can make up a Casparian Strip and is the location of expansin, which is influenced by auxin and mediates acid growth. These structures, which have been modeled using the diffuse layer model and the covalent cross-link model, also make up tracheids and often are interrupted by plasmodesmata. For 10 points, identify these structures, secondary types of which contain a lot of lignin, that make up xylem and are composed of hemicellulose and cellulose.
