The molecular characterization of the lignin-forming peroxidase. Progress summary report, April 1, 1992--March 31, 1995

PDF Version Also Available for Download.

Description

My research program focuses entirely on the study of the lignin-forming peroxidase of tobacco. Ever since our cloning and sequencing of the first plant peroxidase cDNA, we have pioneered in the introduction of the tools of molecular biology to the study of plant peroxidases. A significant part of our effort has been focused on the construction and analysis of transgenic plants which either over- or under-express the tobacco anionic peroxidase. This research has not only supported the role for this enzyme in lignification, but has opened the door to our understanding of additional metabolic functions including auxin metabolism and insect ... continued below

Description

My research program focuses entirely on the study of the lignin-forming peroxidase of tobacco. Ever since our cloning and sequencing of the first plant peroxidase cDNA, we have pioneered in the introduction of the tools of molecular biology to the study of plant peroxidases. A significant part of our effort has been focused on the construction and analysis of transgenic plants which either over- or under-express the tobacco anionic peroxidase. This research has not only supported the role for this enzyme in lignification, but has opened the door to our understanding of additional metabolic functions including auxin metabolism and insect defense. As you will learn, this enzyme`s role in auxin catabolism has lead to numerous phenotypes in transgenic plants. More recently, our attention has been directed towards the analysis of peroxidase gene expression. From this work we have learned that the anionic peroxidase gene is expressed at high levels in the xylem-forming cells, epidermis, and trichomes. This expression pattern supports its role lignification and hose defenses. We have also learned that this gene is down-regulated by auxin which indicates a strong relationship between auxin and the anionic peroxidase. 12 figs.
