Abstract:
Glycosylphosphatidylinositol-anchored proteins were reported to be involved in many developmental progresses in Arabidopsis. Here I report that, a group of homologous glycosylphosphatidylinositol-anchored proteins from SKU5-Similar family regulate seedling root development of Arabidopsis through controlling cell polar expansion and cell wall synthesis. Due to the irregular expansion of root cells and the defective synthesis of cell walls, their knockout mutants generated shorter roots with irregularly shaped root cells, and thicker cell walls.
