Abstract

Polyclonal antisera against a fusion protein of β-galactosidase and the 20 C-terminal amino acids of the Arabidopsis thaliana sucrose carrier AtSUC2 were used to determine the cellular localization of the AtSUC2 protein. Using fluorescence-labelling on sections from different organs of Arabidopsis the AtSUC2 protein was immunolocalized exclusively in companion cells. The presented data indicate that phloem loading in Arabidopsis may be catalyzed by the AtSUC2 sucrose carrier which transports sucrose into the companion cells. No evidence for a participation of the second Arabidopsis sucrose transporter AtSUC1 has been obtained.
