Application

Application Comment Organism
industry downregulation of CCR in transgenic poplar (Populus tremula x Populus alba) is associated with up to 50% reduced lignin content and an orange-brown, often patchy, coloration of the outer xylem. Lignin is relatively more reduced in syringyl than in guaiacyl units. Elevated ferulic acid levels, ferulic acid is incorporated into the lignin via ether bonds. Reduced levels of lignin and hemicellulose are associated with an increased proportion of cellulose. Stress response induced by altered cell wall structure. Chemical pulping of wood derived from 5-year-old, field-grown transgenic lines reveal improved pulping characteristics, but growth is affected in all transgenic lines tested. Trees harboring CCR alleles that result in reduced CCR activity are interesting progenitors for breeding programs. The lower lignin and hemicellulose levels and associated relative increase in cellulose suggest that CCR downregulation may be a good strategy to improve plant biomass for bioethanol production Populus trichocarpa
