Abstract
Summary: In mesophyll cells of Vallisneria gigantea, an aquatic angiosperm, the intact adhesion of plasma membrane to cell wall at the end walls is indispensable to maintain the stationary arrangement of actin microfilaments.Possible involvements of intracellular actin-binding proteins, transmembrane proteins, and cell wall proteins, in an analogous way to the components located at animal focal contact, in the organization of actin cytoskeleton are discussed.
