Fig. 4 Expression of a heterologous gene, uidA, by the two SAD gene promoters during linseed seed development and in relation to fatty acid and protein biosyntheses. For GUS assays, the data represent means of assays done on T1 progeny of two plants transformed with a tandem 35S promoter (2x35S) construct, T1 and T3 progeny of two plants transformed with pCDC214 (SAD1) construct, and T1 and T3 progeny of a plant transformed with pCDC220 (SAD2) construct. For fatty acids, three individual embryos of linseed cv. McGregor were analyzed at various stages. For protein content, data are means of estimations done on two transgenic plants transformed with pCDC214 and 220
