abstract = {Introduction
As key-players of plant immunity, the proteins encoded by resistance genes (
R
-genes) recognize pathogens and initiate pathogen-specific defense responses. The expression of some
R
-genes carry fitness costs and therefore inducible immune responses are likely advantageous. To what degree inducible resistance driven by
R
-genes is triggered by pathogen infection is currently an open question.
Methods
In this study we analyzed the expression of 940
R
-genes of tomato and potato across 315 transcriptome libraries to investigate how interspecific interactions with microbes influence
R
-gene expression in plants.
Results
We found that most
R
-genes are expressed at a low level. A small subset of
R
-genes had moderate to high levels of expression and were expressed across many independent libraries, irrespective of infection status. These
R
-genes include members of the class of genes called NRCs (NLR required for cell death). Approximately 10\% of all
R
-genes were differentially expressed during infection and this included both up- and down-regulation. One factor associated with the large differences in
R
-gene expression was host tissue, reflecting a considerable degree of tissue-specific transcriptional regulation of this class of genes.
Discussion
These results call into question the widespread view that
R
-gene expression is induced upon pathogen attack. Instead, a small core set of
R
-genes is constitutively expressed, imparting upon the plant a ready-to-detect and defend status.},
