  • COATINGS FOR MEASURING PH CHANGES
    Publication number: 20140356974
    Abstract: A pH detectable coating. The pH detectable coating includes a pH insensitive fluorescent dye and a pH sensitive fluorescent dye. The pH insensitive fluorescent dye and the pH sensitive fluorescent dye are attached to a surface. The ratio of the fluorescent intensity of the pH insensitive fluorescent dye to the fluorescent intensity of the pH sensitive fluorescent dye varies according to the pH of an environment into which the surface is placed.

  • Genetic engineering of plants through manipulation of lignin biosynthesis
    Patent number: 6969784
    Abstract: The invention pertains to the genetically down regulating a lignin pathway p-coumarate Co-enzyme A ligase (CCL) in trees.
    Type: Grant
    Filed: June 27, 2002
    Date of Patent: November 29, 2005
    Assignee: Board of Control of Michigan Technological University

  • 4-coumarate co-enzyme a ligase promoter
    Patent number: 6831208
    Abstract: The present invention provides a Populus 4-coumarate Co-enzyme A ligase gene promoter that directs expression in the xylem of plants. The promoter is used in methods designed to alter lignin content, lignin structure, cellulose content and combinations thereof. The methods comprise operably linking said promoter to heterologous nucleic acid molecules.
