We partially purified peroxidase isoform fractions from xylem extracts of a gymnosperm, Norway spruce (Picea abies (L.) Karst.), and an angiosperm, silver birch (Betula pendula Roth.), to determine the participation of xylem-localized peroxidases in polymerization of different types of lignin in
Monolignol transport during lignification is a partially solved puzzle: both the mechanism(s) and the transported form of monolignols are unknown in developing xylem of trees. We tested a hypothesis of an active, plasma membrane (PM)-localized transport of monolignol monomers, dimers, and/or
A Norway spruce (Picea abies) tissue culture line that produces extracellular lignin into the culture medium has been used as a model system to study the enzymes involved in lignin polymerization. We report here the purification of two highly basic culture medium peroxidases, PAPX4 and PAPX5, and
