Notes:
Borstlap (Naturwissenschaften 68: 41–43, 1981; Plant Cell Environ. 4: 189–195, 1981) has alleged that the concept of multiphasic uptake of solutes in plants is invalid. This claim is considered in detail and shown not to be justified. Contrary to Borstlap, the concentration-dependence of uptake cannot be adequately represented by the sum of two Michaelis-Menten terms and a linear term, or by similar continuous functions, if sufficiently detailed and precise data are used. Published evidence for the multiphasic concept, including the existence of discontinuities and separate uptake and transition sites, remains valid.
