To investigate whether Cd induces common plant defense pathways or unspecific necrosis, the temporal sequence of physiological reactions, including hydrogen peroxide (H(2)O(2)) production, changes in ascorbate-glutathione-related antioxidant systems, secondary metabolism (peroxidases, phenolics, and lignification), and developmental changes, was characterized in roots of hydroponically grown Sc...
The lignification of xylem is an adaptive trait of great significance. Gymnosperms and angiosperms share an ancient, conserved set of enzymes that are regulated by a conserved transcription factor and that are responsible for the formation of guaiacyl lignin. Angiosperms have evolved at least two enzymes that catalyze the production of syringyl lignin. Association genetics is now being used to ...
Recent studies on mutant and transgenic plants indicate that lignification may be far more flexible than previously realized. Pines with a mutation affecting the biosynthesis of the major lignin precursor, coniferyl alcohol, show a high level of an unusual subunit, dihydroconiferyl alcohol. These results argue in favor of an increased potential for genetic modification of lignin and indicate th...
