Abstract

The aims are to determine the effects of modifications to lignin structure on plant decomposition in soils, effects of soil conditions on the decomposition of plants with modified lignin (including interactions), and value of such plants as models in decomposition studies. Tobacco with different lignins (arising from specific down- regulation of biosynthesis enzymes) will be grown in 13CO2 and their decay in contrasting soils determined by 13C and CO2 loss. Transformations in lignin and other organic constituents will be followed by solid-state 13C and 15N NMR methods, including relaxation editing techniques to assess polymerisation/depolymerisation both initially between different lignins and during decay.
