Changes in expression of seed storage protein genes effected by chromosome 1D of wheat

Abstract

The effect of chromosome 1D of wheat on expression of seed storage protein genes was analyzed using a 1R(1D) substitution line and derivatives of this line that had lost 1R (1D nullisomic). The results of one- and two-dimensional (two pH) electrophoresis suggested that nucleotide sequences located on 1D were involved in induction and suppression of these protein genes and in posttranscriptional modification of polypeptides produced by the seed storage protein genes. The action attributed to 1D appeared to affect only genes located on chromosome 6A.Key words: electrophoresis, gene expression, suppression, Triticum aestivum.
