Evidence that sucrose loaded into the phloem of a poplar leaf is used directly by sucrose synthase associated with various beta-glucan synthases in the stem.

Plant physiology - 1 Mar 2004

Abstract excerpt

Sucrose (Suc) synthase (SuSy) is believed to function in channeling UDP-Glc from Suc to various beta-glucan synthases. We produced transgenic poplars (Populus alba) overexpressing a mutant form (S11E) of mung bean (Vigna radiata) SuSy, which appeared in part in the microsomal membranes of the stems. Expression of SuSy in these membranes enhanced the incorporation of radioactive Suc into cellulose, together with...
