Activation of Soluble Acid Invertase Accompanies the Cytokinin-Induced Source–Sink Leaf Transition

Activation of Soluble Acid Invertase Accompanies the Cytokinin-Induced Source–Sink Leaf Transition Activation of soluble acid invertase by cytokinin was shown using as a model a detached sugar-beet leaf, one half (sink) of which was treated with benzyladenine and the other half (source) of which was sprayed with water. Acid invertase was assumed to mediate the hormone-induced sink properties of the cells. The influx of 14C-sucrose to the leaf half treated with benzyladenine was induced to much greater extent than that of potassium (86Rb).

Abstract

Activation of soluble acid invertase by cytokinin was shown using as a model a detached sugar-beet leaf, one half (sink) of which was treated with benzyladenine and the other half (source) of which was sprayed with water. Acid invertase was assumed to mediate the hormone-induced sink properties of the cells. The influx of 14C-sucrose to the leaf half treated with benzyladenine was induced to much greater extent than that of potassium (86Rb). This suggests different pathways or mechanisms of translocation of these substances to the induced sink.
