The present invention relates generally to isolated genes which encode polypeptides involved in cellulose biosynthesis in plants and transgenic plants expressing same in sense or antisense orientation, or as ribozymes, co-suppression or gene-targeting molecules. More particularly, the present invention is directed to a nucleic acid molecule isolated from, wheat, barley, maize,spp.,andspp. which encode or an enzyme which is important in cellulose biosynthesis, in particular the cellulose synthase enzyme and homologues, analogues and derivatives thereof and uses of same in the production of transgenic plants expressing altered cellulose biosynthetic properties.

Manipulation of cellulose and/or &#x3b2;-1,4,-glucan

The present invention relates to an isolated and purified DNA comprising a nucleotide sequence that encodes a polypeptide functionally involved in the DNA mismatch repair system of a plant.

Isolated DNA that encodes an Arabidopsis thaliana MSH3 protein involved in DNA mismatch repair and a method of modifying the mismatch repair system in a plant transformed with the isolated DNA

The invention relates generally to isolated genes which encode polypeptides involved in cellulose biosynthesis in plants and transgenic plants expressing same in sense or antisense orientation, or as ribozymes, co-suppression or gene-targeting molecules. More particularly, the present invention is directed to a nucleic acid molecule isolated from wheat, barley, maize, Brassica ssp., ssp. and Eucalyptus ssp. which encode an enzyme which is important in cellulose biosynthesis, in particular the cellulose synthase enzyme and homologues, analogues and derivatives thereof and uses of same in the production of transgenic plants expressing altered cellulose biosynthetic properties.
