Abstract: | A geranylgeranyl pyrophosphate synthase (GGPPS) gene from Capsicum annuum (bell pepper) was cloned. The nucleotide sequence shows that this gene, like the capsanthin/capsorubin gene but unlike the phytoene synthase gene from C. annuum, is not interrupted by an intron. Southern blot analysis of C. annuum genomic DNA suggests the presence of a single gene highly similar to the cDNA and also of additional related sequences. The present data suggest that this cloned gene is functional. |
