author keywords: CINNAMYL ALCOHOL DEHYDROGENASE; PINE; LIGNIN BIOSYNTHESIS; DNA SEQUENCE; GENOME; EVOLUTION
MeSH headings : Alcohol Oxidoreductases / chemistry; Alcohol Oxidoreductases / genetics; Amino Acid Sequence; Base Sequence; Biological Evolution; Cloning, Molecular; Gene Expression Regulation, Enzymologic; Isoenzymes / chemistry; Isoenzymes / genetics; Molecular Sequence Data; Pinus taeda; Plants / enzymology; Plants / genetics; Sequence Alignment; Sequence Analysis
TL;DR: The presence of a single gene suggests that different regulatory mechanisms for a single Cad gene, rather than differential regulation of several genes, can account for its expression in response to different cues. (via Semantic Scholar)

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)

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.

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.
