Abstract

In an experiment with double girdling of silver birch trunk the assimilate transport in the phloem was interrupted. This allowed to create sucrose concentration gradients along the trunk axis. In zones of growth and differentiation of conducting tissues (phloem, xylem), at different distances from the girdling zone the expression level of the genes encoding the apoplastic invertase (CWIN), its protein inhibitor (Cif), the isoforms of sucrose synthase (Sus1, Sus2) and cellulose synthase (Ces3, Ces7, Ces8) was studied.
