Lineage-specific genomic regions of Verticillium dahliae strain JR2 are enriched for in planta-expressed genes. Deep transcriptome sequencing of infected Nicotiana benthamiana plants harvested between 4- and 16-d post-inoculation (DPI), and fungus cultured on Czapek Dox medium (C) led to the identification of 19 highly in planta-induced genes [log10(FC) > 2.15]. Of these, eight are located in lineage-specific (LS) regions (in blue), while 11 are in the core genome (in red), demonstrating significant overrepresentation of in planta-expressed genes in LS regions. The table shows the presence (black) or absence (white) of in planta-induced JR2 genes within the set of sequenced strains and indicates hypothetical and putatively secreted proteins. Numbers in the two gray cells indicate amino acid identity and conservation, respectively, for two divergent homologs.
