POLYNUCLEOTIDE COMPRISING SEQUENCES OF WHEAT GLIADINS AND USE THEREOF FOR SILENCING BY RNAI

摘要

The present invention relates to the specific silencing of the .alpha.(alpha),.beta.(beta), .gamma.(gamma) and .omega. (omega)-gliadinsof hard wheat for flour by RNA interference (RNAi) through employment of apolynucleotide which is transcribed into an hpRNA(hairpin RNA). Furthermore the present invention additionally relates to avector, cell, plant or seed comprising thepolynucleotide, the expression whereof is specifically directed in particulartissues of wheat seeds through gene expression--regulatingsequences such as, for example, the promoter of a gene of .gamma.-gliadins orthe promoter of the gene encoding for aD--hordein.
