NMR Evidence for benzodioxane structures resulting from incorporation of 5-hydroxyconiferyl alcohol into lignins of 0-methyltransferase-deficient poplars

Edité par CCSD ; American Chemical Society -

International audience. Benzodioxane structures are produced in lignins of transgenic poplar plants deficient in COMT, an O-methyltransferase required to produce lignin syringyl units. They result from incorporation of 5-hydroxyconiferyl alcohol into the monomer supply and confirm that phenols other than the three traditional monolignols can be integrated into plant lignins.
