Abstract
A gene cassette, p35S-CNO, was designed to express three gene products driven by a single constitutive CaMV 35S promoter. The individual coding regions were linked in frame to produce a single polyprotein, using spacer sequences encoding a specific heptapeptide cleavage recognition site (ENLYFQS) for the nuclear-inclusion-a (NIa) proteinase of tobacco etch virus (TEV). The protein coding sequences used were: a Trichoderma harzinum endochitinase, a truncated NIa proteinase of TEV, and a wheat oxalate oxidase. When p35S-CNO construct was tested in Arabidopsis thaliana, the polyprotein was properly cleaved after translation and the products exhibited functional enzymatic activity in vivo.
