The Conversion of Sucrose to Starch in Developing Fruits

Abstract

AbstractAlthough the flow of carbon from sites where it is assimilated to its eventual destination as starch is, for convenience, investigated as a large number of partial processes, it is nevertheless possible to conceive of a simple unifying model: the plant as a set of conductors for reduced carbon compounds, the direction of flow and the flux being determined by gradients of concentration and resistance to movement (Beevers 1969, Jenner 1974 a). This simple idea can explain what is known about the overall process, and one attractive feature of a recent hypothesis on the nature of the regulatory mechanism (Herold and Walker 1979) is that it spans the gap between origin and destination.
