Zusammenfassung:Improved supersweet corn plants, in addition to their naturally occurring homozygous recessive sh-2 or bt-2 genes, also have an ADP-GPP subunit gene under the control of a heterologous promoter. The heterologous promoter may either be developmentally delayed so that it is active only after approximately 25 or 30 days post pollination, or it may be an inducible promoter. The improved kernels are supersweet when harvested for food, but are starchy when harvested as a seed crop. Alternatively an anti-sense ADP-GPP subunit gene under the control of an inducible promoter or a promoter which is active during early endosperm development may be used to transform a sweet corn plant such that transcription of the anti-sense gene blocks ADP-GPP synthesis giving rise to supersweet kernels.
