Methods and Means for modulating Cellulose biosynthesis in Plants producing Fibers

摘要

New genes involved in the biosynthesis of Cellulose and Methods for using the Modulation of these genes in the biosynthesis of Cellulose in Plants producing Fibers, such as cotton. It also provides methods for identifying and isolating alleles of these genes in a population of P Lantas produce Fibers that are correlated with the quality of the Fibre produced.Claim 1: a method to increase the biosynthesis of Cellulose in Fiber producing plants, in particular in cotton plants.Characterized in that it comprises the steps of: providing the plant Fibres Producer cells with a Chimeric Gene Fragments of DNA that includes the following: (i) a promoter operably linked to express in the cell of the Plant; (ii) a region of DNA that encodes the A protein comprising the amino acid sequence of the SEQ ID no: 5 or 6 of the SEQ ID no: or the seqID no: 7 or 8 of the SEQ ID no: or a variant of it, where such variants have the same Enzymatic activity; (iii) a region involved in the 3 'end of the transcript and the polyadenylation. Claim 30: a Plant Cell, characterized in that it comprises the Gene. Imu00e9rico of any of Claims 17 to 29.Plant: a claim 31, wherein consists mainly of plant cells of 30 claims. Claim 32: a seed of the plant of claim 31, wherein the Chimeric genes comprising any of Claims 17 to 29.
