| Outline of Final Research Achievements |
Lignin have negative impacts on the biochemical process for producing lignocellulosic biofuels, forage digestibility, and the kappa value in the pulping industry. We recently demonstrated that deficiency of plant peroxidases (Prx) involved in Arabidopsis stem lignification led to both decreased total lignin content and increased uncondensed units of lignin. In this study, we showed simultaneous disruption of these Prx genes resulted in enhancing the phenotypic traits of each single mutant, suggesting that manipulation of Prx genes is an attractive strategy to improve lignin characteristics.
