Title Tip Growth Morphogenesis: From Molecules to Cell Shape
Abstract Many features of tip growth are shared across a wide range of organisms and seem therefore to transcend differences in wall composition and subcellular architecture. Based on this observation, we suggest a generic model of tip growth and show how it can account for many aspects of cell morphogenesis in fungi, oomycetes, and plants. One of the most difficult issues remains to formulate a set of equations for cell surface expansion that includes both the addition of new wall material and its stretching into a functional shape. We will discuss how our model unites these two processes and show how it can account for the steady growth of cells as well as non-steady responses.
