Exploring the determinants of lifestyle of Colletotrichum tofieldiae under high temperature
Colletotrichum tofieldiae (Ct) is a species of root-associated fungus with context-dependent lifestyles.  At 22C, strain Ct3 is a pathogen under Pi sufficient and deficient conditions, while strain Ct4 is a mutualist under Pi deficient conditions.  At 26C, however, Ct3 shifts to become a plant-growth-promoting fungus under Pi sufficient and deficient conditions.  This is at least partly explained by differential expression of a secondary metabolism biosynthesis cluster necessary for pathogenicity at 22C, which is downregulated at 26C.  However, we hypothesized there may be other determinants of lifestyle that are differentially expressed at 26C compared to 22C.  Therefore, we extracted RNA from 12 dpi Arabidopsis thaliana Col-0 roots inoculated with Ct3 or Ct4 under Pi sufficiency or deficiency.  These data represent the raw RNA-seq reads from this experiment.
