Transcriptomic responses in Arabidopsis thaliana to PIPL3 peptide treatment

ABSTRACT: 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. 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.

Peptide ligands play crucial roles in the life cycle of plants by modulating the innate immunity against pathogens and regulating growth and developmental processes. One well-studied example is INFLORESCENCE DEFICIENT IN ABSCISSION (IDA), which controls floral organ abscission and lateral root emergence in Arabidopsis thaliana. IDA belongs to a family of five additional IDA-LIKE (IDL) members that have all been suggested to be involved in regulation of Arabidopsis development. Here we present th ...[more]

The IDA-LIKE peptides IDL6 and IDL7 are negative modulators of stress responses in Arabidopsis thaliana

Project description:We present a functional characterisation of two members of the IDA-LIKE (IDL) peptide family in Arabidopsis thaliana, IDL6 and IDL7. They are processed both C- and N-terminally to produce active peptides. Structure analyses of synthesized IDL6 and IDL7 peptides indicate that they lack secondary structure elements. Localisation studies suggest that the peptides require a signal peptide and C-terminally processing to be correctly transported out of the cell. Treatment of plants with synthetic IDL6 and IDL7 peptides resulted in down-regulation of a broad range of stress-responsive genes, including early stress-responsive transcripts, dominated by a large group of ZINC FINGER PROTEINS (ZFPs), WRKYs and genes encoding calcium-dependent proteins. idl6 and idl7 mutants were more tolerant to salt, whereas the respective overexpression lines displayed increased sensitivity to both salt and oxidative stress. Taken together, our results suggest that the putative peptide ligands IDL6 and IDL7 act as suppressors of abiotic stress responses in Arabidopsis. Two weeks old seedlings were treated either with 100 nM IDL6 or IDL7 peptide (treated) or 100 nM mock peptide (control) and whole rosettes were harvested 2 hours after treatment. 4 biological replicaes per treatment. Two color microarray. Biological replicas are dye-swapped between slides.

PSY1 responding transcripts in two plant lines of Arabidopsis thaliana

Project description:Plant peptide containing sulfated tyrosine 1 (PSY1) has been reported to promote cell expansion and differentiation in the elongation zone of roots. To further understanding of PSY1 based cell elongation, a full genome microarray study was conducted on wild type and receptor (psy1r) mutant plants after PSY1 treatment. This approach led us to elucidate the components involved in PSY1 based cell elongation. Two plant lines (Wild type and psy1r) were grown hydroponically for one week and following treated with 10 nM PSY1 for 4 hr before RNA extraction for micorarray. Three independent biological samples were prepared

INFLORESCENCE DEFICIENT IN ABSCISSION (IDA) and its receptors HAE/HSL2 are required for cell expansion and cell separation during floral organ abscission in Arabidopsis thaliana (part 2)

Project description:Plants have the ability to shed organs that are no longer in use. In Arabidopsis thaliana abscission of floral organs involves cell wall remodeling and cell expansion prior to cell wall dissolution. IDA encodes a secreted peptide that signals through the leucine-rich repeat receptor-like kinases (LRR-RLKs) HAESA (HAE) (At4g28490) and HASEA-LIKE2 (HSL2) (At5g65710). Arabidopsis thaliana (ecotype Colombia-0) plants were kept in growth chambers with a 16/8 h (light/dark) photoperiod at 22 M-BM-0C, and 100 mE m-2 s-1 light intensity. 4 biological replicates were prepared from each sample, each containing abscission zone regions of siliques position 4 to 8 (when counting from the flowe at anthesis at the top of the inflorescence) from plants with at least 20 siliques. Differences in transcriptional responses were measured by comparing genes expression in abscission zones of ida-2 plants (SALK_133209) against abscission zones from control plants.
