Identification and characterization of rye genes not expressed in allohexaploid triticale.

ABSTRACT:

Background

One of the most important evolutionary processes in plants is polyploidization. The combination of two or more genomes in one organism often initially leads to changes in gene expression and extensive genomic reorganization, compared to the parental species. Hexaploid triticale (x Triticosecale) is a synthetic hybrid crop species generated by crosses between T. turgidum and Secale cereale. Because triticale is a recent synthetic polyploid it is an important model for studying genome evolution following polyploidization. Molecular studies have demonstrated that genomic sequence changes, consisting of sequence elimination or loss of expression of genes from the rye genome, are common in triticale. High-throughput DNA sequencing allows a large number of genes to be surveyed
