1999 journal article

Average effect of a mutation in lignin biosynthesis in loblolly pine

THEORETICAL AND APPLIED GENETICS, 99(3-4), 705–710.

By: R. Wu n, D. Remington n, J. MacKay*, S. McKeand n & . DM O'Malley n

author keywords: average effect; CAD; lignin biosynthesis; loblolly pine; mutant; RAPDs
TL;DR: It is found that the substitution of a wild-type allele by cad-n1 was associated with a significant effect on 2nd-year shoot elongation in a half-sib family of loblolly pine (designated family 7–1037), and the average effect appeared to increase with tree growth and was greater for stem radial growth than height growth.

1999 journal article

Modified lignin and delignification with a CAD-deficient loblolly pine

HOLZFORSCHUNG, 53(4), 403–410.

By: J. MacKay*, T. Presnell, H. Jameel*, H. Taneda, . D O'Malley & R. Sederoff*

author keywords: pine; genetic modification; lignin mutant; delignification; soda pulping; coniferaldehyde
TL;DR: More extensive lignin removal, both in mild alkali treatment and in soda pulping, indicate that suppression of CAD in softwood trees may hold promise to produce woods well suited for “milder” pulping conditions that consume less chemicals and generate less waste. (via Semantic Scholar)

1999 review

Unexpected variation in lignin

[Review of ]. CURRENT OPINION IN PLANT BIOLOGY, 2(2), 145–152.

MeSH headings : Alcohol Oxidoreductases / genetics; Alcohol Oxidoreductases / metabolism; Lignin / biosynthesis; Lignin / chemistry; Mutation; Phenols / metabolism; Plants, Genetically Modified; Trees / genetics; Trees / metabolism
TL;DR: The results argue in favor of an increased potential for genetic modification of lignin and indicate that the knowledge of the biosynthesis of lIGNin is far from complete. (via Semantic Scholar)

1998 journal article

Characterization of NAD-dependent mannitol dehydrogenase from celery as affected by ions, chelators, reducing agents and metabolites

PLANT SCIENCE, 131(1), 43–51.

By: J. Stoop n, J. Williamson n, M. Conkling n, J. MacKay n & D. Pharr n

author keywords: adenylate inhibition; mannitol dehydrogenase; mannitol metabolism; plant carbohydrates; redox regulation; zinc binding
TL;DR: Inhibition by the chelator 1,10-phenanthroline suggests that zinc is required for MTD activity, and the observed down-regulation of MTD in salt stressed celery is not due to a direct inhibition by NaCl or macronutrients. (via Semantic Scholar)

By: R. Whetten n, J. MacKay n & R. Sederoff n

author keywords: monolignol biosynthesis; lignin composition; pulp manufacturing; forage quality; metabolic plasticity
TL;DR: These results argue that the accepted lignin biosynthetic pathway is either incomplete or incorrect, or both; and also suggest that plants may have a high level of metabolic plasticity in the formation of lignins. (via Semantic Scholar)
