Divergence and conservation of differential gene expression of TNLs and DEFLs in Arabidopsis pistils and leaves infected by Fusarium graminearum. a Most differentially expressed TNLs in the species analyzed are significantly upregulated in infected leaves or pistils of the Arabidopsis species investigated. A large proportion of the genes upregulated belong to three top largest subgroups of genes in this family: GT1, GT3 and GT10. Asterisks indicate groups with significant positive selection. Additional file 10: Data 7 provides further details of other genes under selection and upregulated during Fusarium infection. b DEFLs differentially expressed in response to Fusarium graminearum are often upregulated in both pistils and leaves. A large proportion belongs to S119 and S124, two relatively large groups with representatives from all species investigated. On top of the corresponding columns the names of DEFL genes from A. thaliana and A. halleri are indicated, which are discussed in the text due to their involvement in pathogen killing and heavy metal resistance. c The largest group of differentially expressed DEFLs in Arabidopsis involves those downregulated during pistil infection. Although these genes belong to a variety of different groups, a large proportion of them are members of CRP0570 and CRP0830
