Cellulosic materials such as cotton fabrics and paper are crosslinked with a composition comprising (A) polymers of ethylenically unsaturated polycarboxylic acid monomers or salts thereof, the monomers having one or more dicarboxylic groups wherein the carboxyl groups are on adjacent carbon atoms; (B) saturated .alpha.-hydroxypolycarboxylic acids or salts thereof; and (C) one or more curing catalysts, and heated to produce esterification and crosslinking of the celluose by reaction of the cellul...

Synthetic methods for lactone-containing compounds such as the discodermolides are provided, as are compounds which mimic the chemical and/or biological activity thereof, and methods and intermediates useful in their preparation.

The present invention is directed to nucleic acid sequences for constitutive triple response mutants and corresponding amino acid sequences. Several ctr mutations are included within the scope of the present invention. The nucleic acid sequences set forth in SEQUENCE ID NUMBERS 1, and 3-6 as well as amino acid sequences set forth in SEQUENCE ID NUMBERS 1 and 2 are particular embodiments of the present invention.
