Effects of gravity on the expression of arabinogalactan-proteins in Arabidopsis

ArabinoGalactan-Proteins (AGPs), a family of proteoglycans, are commonly found in higher plants and implicated in many physiological processes such as cell-to-cell signaling, cell adhesion, cell elongation, cell death, and stress responses. We examined the effects of hypergravity on expression of AGP species in Arabidopsis plants. Several AGP species including classical AGP, AG-peptide, and fasciclin-like AGP showed decreased expression under hypergravity conditions. Visualization of the AGP species with GFP (Green Fluorescent Protein) revealed their tissue-specific expression and confirmed the altered expression under hypergravity. The results suggest that AGPs play a role in the gravity response of higher plants.
