RNAseq of wt and receptor mutant lines in response to 7 elicitor treatments over a 6-point time course

The degree to which plants discriminate among elicitors in early transcriptional responses is unknown. To test this, we selected a panel of seven elicitors recognized by the model plant Arabidopsis thaliana. Two-week old Arabidopsis seedlings in liquid culture were treated with each elicitor individually, and tissue flash-frozen at 0, 5, 10, 30, 90, and 180 min post-treatment. As a control, receptor mutants for each elicitor were treated and harvested in parallel with wt plants. The experiment was repeated four times. mRNA was extracted via pulldown of poly-A tail from bulk lysate, and libraries were prepared via tagmentation with custom Tn-5 adapter oligos. Libraries for each experiment were pooled, and sequenced across 2-3 flowcells of a NextSeq500 benchtop sequencer.
