| abstract |
The present invention relates to the specific silencing of the .alpha.(alpha), .beta.(beta), .gamma.(gamma) and .omega. (omega)-gliadins of hard wheat for flour by RNA interference (RNAi) through employment of a polynucleotide which is transcribed into an hpRNA (hairpin RNA). Furthermore the present invention additionally relates to a vector, cell, plant or seed comprising the polynucleotide, the expression whereof is specifically directed in particular tissues of wheat seeds through gene expression--regulating sequences such as, for example, the promoter of a gene of .gamma.-gliadins or the promoter of the gene encoding for a D--hordein. |
