Global analysis of proline-rich tandem repeat proteins reveals broad phylogenetic diversity in plant secretomes.

Cell walls, constructed by precisely choreographed changes in the plant secretome, play critical roles in plant cell physiology and development. Along with structural polysaccharides, secreted proline-rich Tandem Repeat Proteins (TRPs) are important for cell wall function, yet the evolutionary diver...
