Triticeae crops
Wheat• Bread wheat (Triticum
aestivum) accounts for 20% of human consumption of calories and protein.
• Hexaploid (AA/BB/DD)– 7 chromosomes– 17Gb genome– ~80% repeats
• Currently only a fragmented assembly is available.
Barley• Barley (Hordeum vulgare)
an important cereal and model for ecological adaption.
• Diploid– 7 chromosomes– 5.3Gb Genome– ~80% repeats
• Integrated gene-space and physical map.

• Shown in the syntenic context of Brachypodium distachyon– Small, model grass
• Diploid• 270 Mbp• Relatively low repeat
density
21
• Sub-assemblies classified into homoeologous chromosomes
• Homoeologous SNPs (SNPs between A, B, and D genomes) mapped onto brachypodium.
