Full-length rice PETC cDNAwas expressed in an antisense orientation under the control of rice RBCS
promoter for its antisense suppression. (b) Proteins in the leaf extract were separated by sodiumdodecyl sulphate–polyacrylamide gel electrophoresis
(SDS–PAGE) and immunodetected with specific antibodies. The extracted proteins for each sample were loaded on gel using an equal leaf area basis;
the series of dilutions for wild-type plants are indicated. (c) Contents of Rieske FeS protein and cytochrome f of the cyt b6/f complex in transgenic
plants were shown as a percentage relative to wild-type.Wild-type: filled triangle, Transgenic plants: open circle. The regression line between Rieske
FeS protein and cytochrome f content is shown.
