Fig. 1. Schematic representation of the T-DNA region of (A) pCAMBIA-ACA which carried the Allium cepa agglutinin (ACA) gene; and (B) pCAMBIA-ASAL::ACA which carried the fusion lectin (ASAL::ACA) gene; 2x35S, doubly enhanced CaMV35S promoter; hypt II, hygromycin resistance gene; Nos, nopaline synthase transcriptional terminator; RB, right border; LB, left border. ASAL, Allium sativum leaf agglutinin.
