Brachypodium – Arabidopsis for cereal crops
ArabidopsisBiologically different to grasses (eg: cell wall composition, development, grain production)
Brachypodium???Bridge the gap for the research areas not reached
YES – it has already proven to be a valuable reference species for comparative analyses in addition to its “model system” toolkit
Brachypodium Wheat
Has revealed extent and nature of variation in grains

Summaries…
- Extent and nature variation in Brachypodium is valuable for comparative study of grain development
- Using Brachypodium, we suggest an interesting gene that might be involved during grain development based on preliminary data.
