A) HRGP (hydroxyprolinerich glycoprotein)                                  i) Xylem, fibers, cortex, root hairs

B) AGP (arabinogalactan protein)                                                  ii) Primary xylem and phloem

C) PRP (proline-rich protein)                                                           iii) Cambium, vascular parenchyma

 D) GRP (glycine-rich protein)                                                          iv) Varied cell-specific expression
