Transcriptomic responses in Arabidopsis thaliana to PIPL3 peptide treatment. Arabidopsis thaliana

In order to investigate possible roles of IDL and PIP/PIPL peptides, the transcriptomic response of Arabidopsis seedlings to treatment with PIPL3 peptide was analysed. PIPL3 (At4g37295) was chosen, as no functional data was available for this peptide; furthermore, PIPL3 was expressed in leaf tissue during seedling stages. Transcriptomic responses to 3 hours PIPL3 peptide treatment suggested a role in regulation of biotic stress responses and cell wall modification. Overall design: Two weeks old seedlings were treated either with 100 nM PIPL3 peptide (treated) or 100 nM mock peptide (control) and whole rosettes were harvested 3 hours after treatment. 4 biological replicates per treatment.
