Interactions between barley and Blumeria graminis

This interaction offers many advantages as model for studying defence mechanisms in plants

• Synchronised development of inoculum.
• Well characterised cytology. Possible to do studies at the single cell level.
• Analysis of cell content
• Altered gene expression by RNAi or transient over expression
• VIGS being developed.
• Availability of good genetic material.
• TILLING populations. Map based cloning has been achieved.

Our current efforts concern two barley genes involved in signal transduction and gene regulation, a DUF26 receptor-like protein kinase and a NAC transcription factor HvNAC6/ATAF1.
