What is it about?
To sum up, codon-optimized VvSTS1 gene coding for stilbene synthase was designed using grapevine stilbene synthase sequence. Molecular analysis of T2 homozygous transgenics revealed the presence of RV, indicating the successful introduction of the pathway of stilbene biosynthesis into onion. Further, the presence of polydatin in transgenic plants indicates the glycosylation of ectopically synthesized RV by endogenous enzymes. Moreover, the transgenic onion

Why is it important?
The novel developed transgenic onion endowed with ectopic stilbenes contributed to ncreased life span of haploid yeast, and as such seems promising to serve as a unique nutraceutical genetic resource.
Perspectives
Genetically engineered onion expressing codon-optimized VvSTS1 gene accumulated stilbenes and extended life span in yeast and can serve as potential nutraceutical.
