Abstract:
Arabinogalactan-proteins (AGPs) are a class of hyperglycosylated, hydroxyproline-rich glycoproteins that are widely distributed in the plant kingdom. AtAGP17, 18 and 19 are homologous genes encoding three classical lysinerich AGPs in Arabidopsis. We observed subcellular localization of AtAGP18 at the plasma membrane by expressing a translational fusion gene construction of AtAGP18 attached to a green fluorescent protein (GFP) tag in Arabidopsis plants. We also overexpressed AtAGP18 without the GFP tag in Arabidopsis plants, and the resulting transgenic plants had a short, bushy phenotype. Here we discuss putative roles of AtAGP18 as a glycosylphosphatidylinositol (GPI)-anchored protein involved in a signal transduction pathway regulating plant growth and development. © 2011 Landes Bioscience.
