Effector repertoire of Phytophthora betacei : in search of possible virulence factors responsible for its host specificity

It infects tree tomato (Solanum betaceum) in northern South America, but is, under natural conditions, unable to infect potatoes or tomatoes, the main hosts of its sister species P. infestans.
