Functional and biosynthetic investigation of polyisoprenoids in roses leaves.

ABSTRACT:

Main conclusion

In Rosa chinensis, four distinct polyisoprenoid families, including two very long-chain types, are synthesized by only three cis-prenyltransferases, challenging the traditional one-enzyme-one-family model. The presence of very long polyisoprenoids in leaves and young shoots is most probably involved in plant organ development. Although terpenoids in roses have been extensively studied, the polyisoprenoid fraction has remained unexplored. In this work, we provide the first characterization of polyisoprenoid diversity and biosynthesis in roses, revealing unexpected chemical and enzymatic complexity. Four distinct polyisoprenoid families (7-9, 15-25, 26-34, and 35-50 isoprene units) were identified in Rosa chinensis, with very long-chain compounds accumulated in leaves
