Abstract: The present invention relates to compositions and methods for over-expressing pectin methylesterases (PMEs), particularly type 1 PMEs (PME1s), in plants while maintaining growth as compated to the wild type. The plants of the invention have improved properties compared to the wild type, particularly improved resistance to salinity.

Abstract: The present invention provides a bio-fuel, wood or other product, such as a paper, textile or yarn product. The product can contain material from a transgenic plant over-expressing a nucleic acid molecule encoding an enzyme that causes the plant cell wall to be more water soluble than the wild type.

Abstract: A process for the manufacture of a lignocellulose product, the process comprising the step of mixing in a reaction medium (i) a phenolic polymer being substituted with a phenolic hydroxy group; (ii) a lignocellulose containing material having immobilized to a cellulosic fraction thereof a fusion polypeptide, the fusion polypeptide including an enzyme being capable of catalyzing the oxidation of phenolic groups and a cellulose binding peptide; and (iii) an oxidizing agent. A composition of matter for use in the process and a lignocellulose product obtainable by the process are also disclosed.

Abstract: A process of expressing a recombinant protein in a plant and of isolating the recombinant protein from the plant, the process is effected by (a) providing a plant, a plant derived tissue or cultured plant cells expressing a fusion protein including the recombinant protein and a cellulose binding peptide being fused thereto, the fusion protein being compartmentalized within cells of the plant, plant derived tissue or cultured plant cells, so as to be sequestered from cell walls of the cells of the plant, plant derived tissue or cultured plant cells; (b) homogenizing the plant, plant derived tissue or cultured plant cells, so as to bring into contact the fusion protein with a cellulosic matter of the plant, plant derived tissue or cultured plant cells, to thereby effect affinity binding of the fusion protein via the cellulose binding peptide to the cellulosic matter, thereby obtaining a fusion protein cellulosic matter complex; and (c) isolating the fusion protein cellulosic matter complex.

Abstract: A method of releasing particulates from a solid matrix is provided. The method is effected adding to the solid matrix a degrading enzyme capable of degrading the solid matrix, to thereby release the particulates from the solid matrix.
