A Laccase Associated with Lignification in Loblolly Pine Xylem

Science, 260(5108), 672–674.

By: W. Bao n, D. O'Malley n, R. Whetten n & R. Sederoff n

TL;DR: Results suggest that laccase participates in lignin biosynthesis and therefore could be an important target for genetic engineering to modify wood properties or to improve the digestibility of forage crops. (via Semantic Scholar)

The role of laccase in lignification

The Plant Journal, 4(5), 751–757.

By: D. O'Malley, R. Whetten*, W. Bao, C. Chen n & R. Sederoff

TL;DR: The enzymatic mechanism of monolignol polymerization in lignin biosynthesis is not known, although it has been the subject of significant interest for more than 60 years and strong circumstantial evidence implicates this enzyme in the polymerization of lignIn precursors.

By: R. Whetten n & R. Sederoff n

TL;DR: Widespread application of genetic engineering awaits better methods of gene transfer and a fundamental understanding of the development process of wood formation to help to meet the projected demand for wood and paper products in the next century. (via Semantic Scholar)

Isolation of the eclosion gene cluster and the developmental expression of the Gld gene in Drosophila melanogaster.

The EMBO Journal, 5(11), 2939–2948.

By: D. Cavener*, G. Corbett, D. Cox* & R. Whetten*

MeSH headings : Animals; Carbohydrate Dehydrogenases / genetics; Chromosome Deletion; Chromosome Mapping; Cloning, Molecular; DNA Restriction Enzymes; Drosophila melanogaster / enzymology; Drosophila melanogaster / genetics; Genes; Genetic Complementation Test; Glucose Dehydrogenases / genetics; Mutation; Nucleic Acid Hybridization; Translocation, Genetic
TL;DR: During the development of Drosophila melanogaster the expression of glucose dehydrogenase (GLD) changes from non sex‐limited to male limited and the Gld gene and three other functionally related genes in the eclosion gene cluster are isolated by the method of chromosome walking.
