Gibberellin 20-oxidases, enzymes of gibberellin (GA) biosynthesis, play an important role in (GA) homeostasis. To investigate the regulation of tomato SlGA20ox1 expression, a genomic clone was isolated, its promoter transcriptionally fused to the GUS reporter gene, and the construct used to transform Arabidopsis. Expression was found in diverse vegetative (leaves and roots) and reproductive (flowers) organs. GUS staining was also localized in the columella of secondary roots. GA negative feed… CONTINUE READING
