  • a Functional categories according to MIPS FunCat database.

  • b Number of genes induced ≥2.0-fold by both OGs and B. cinerea and present in the indicated category. In parentheses is indicated the percentage of total OG- and B. cinerea-induced genes that match the category.

  • c Total number of Arabidopsis genes in the indicated functional category. In parentheses is indicated the percentage of genes in the Arabidopsis genome that match the category. The comparison was done to the Arabidopsis thaliana MAtDB containing 26,642 annotated genes (http://mips.gsf.de/projects/funcat).

  • d P value of significance of distribution of OG- and Botrytis-induced genes in the indicated category, compared to distribution in the complete Arabidopsis dataset. Only categories significantly overrepresented (P < 0.001) are indicated in the table.
