Arabinogalactan-proteins (AGPs) are a family of proteoglycans found in the plasma membrane and cell walls of higher plants. AGPs are implicated in many physiological processes such as cell elongation, cell-to-cell signaling, cell adhesion, cell death, and stress responses. The effects of hypergravity on expression of AGP species were examined using AGPs visualized with GFP. The expression level of a classical AGP significantly decreased in the influorescence meristem under hypergravity conditions. The expression level recovered within 2 hours after transfer to 1 g condition. The results indicate that expression level of the AGP is regulated by the magnitude of gravity.
