Abstract

Non-mobile plant cells must expand to achieve its final shape. Polarized diffuse growth is a common mode of cell expansion adopted by most plant cells, in which cell membrane expansion occurs throughout the entire cell surface while the direction of cell expansion is spatially controlled by localized changes in cell wall extensibility. Although the mechanisms underlying these changes are not clear, it is generally surmised that these changes are modulated by the reorganization and dynamics of the cytoskeleton in responses to growth signals. During plant development, endogenous developmental signals such as mechanical forces and plant hormones are proposed to regulate the cytoskeleton by signaling to cytoskeleton-associated proteins. In this review, we summarize known endogenous developmental signals and their signaling pathways in the control of cytoskeletal re-organization and dynamics that impinge upon polarized diffuse cell growth.
