Analysis of the bread wheat grain transcriptome reveals complex genome interplay in a hexaploid cereal.. Analysis of the bread wheat grain transcriptome reveals complex genome interplay in a hexaploid cereal.

Allohexaploid bread wheat (Triticum aestivum, L.) provides ~ 20% of calories consumed by humans. Hitherto lack of genome sequence for the three homoelogous and highly similar bread wheat genomes (A, B and, D) impeded expression analysis of the grain transcriptome. We used novel genome information to analyze the cell type specific expression of homeologous genes in the developing wheat grain.
