Role of HSPs in virulence

[Scott Coutts]

I know that heat shock proteins (especially dnaK, HSP70) play a role in 
animal pathogenesis - there are plenty of papers published about animal 
pathogens being under stress whilst attempting to colonise a host. But... 
does anyone know of an instance where heat shock proteins or other 
stress-responsive proteins play a part in _plant_ pathogenesis?  
Phytopathogens must be placed under some sort of stress in plants, too, 
surely?
