Differences in Arabidopsis gene expression levels between plants infected with prgH− mutant or wild-type 14028 s Salmonella.

All presented genes are included in the cluster 5 (Supplementary Fig. S4A). Log ratio in expression between mock treatment and infection with wild-type bacteria or log ratio in expression between mock treatment and infection with prgH− mutant were calculated using the algorithm developed for analysis of CATMA arrays [50].
