Characterization of the Phytophthora infestans "plastic secretome". A) Frequency of P. infestans genes excluded from orthologous segments between P. infestans and either the P. sojae or P. ramorum genome. The proportion (% of gene group) of all, secretome, known effectors, RXLR effector and CRN effector genes is shown. B) Venn diagram illustrating the number of P. infestans genes (i) residing in GSRs and (ii) not in genome segments orthologous between the three Phytophthora species and (iii) belonging to the secretome. This set of three criteria defines the plastic secretome. The P. infestans plastic secretome consists of 561 genes: 398 known effector genes and 163 others. C) Percentage of various P. infestans gene groups found in the plastic secretome (as a % of the whole gene group). D) The plastic secretome is enriched in in planta-induced genes. The proportion of either plastic secretome (green) or non-plastic secretome (grey) genes induced in planta is shown. Genes induced at any of the time points tested are also shown ('Any'). Tom., infected tomato; Pot., infected Potato; dpi, days post-inoculation.
