Project description:Plant resistance inducers (PRIs) are compounds that protect crops from diseases by activating plant immunity. The exogenous treatment with glutamate (Glu), an important amino acid for living organisms, was shown to induce resistance against fungal pathogen in rice and tomato. To understand the molecular mechanism of Glu-induced immunity, we developed a model system using Arabidopsis thaliana. Here, we found that exogenous treatment with Glu to Arabidopsis enhances resistance against Pseudomonas syringae pv. tomato DC3000 and Colletotrichum higginsianum. Consistently, transcriptome analyses of Arabidopsis seedlings treated with Glu showed that Glu significantly induces the expression of wound, defense, and stress related genes. Interestingly, Glu activates the expression of pathogen or damage associated molecular patterns (PAMP or DAMP)–inducible genes at much later time points than PAMP/DAMPs normally do. Moreover, expression of Glu-inducible genes does not require known components of PAMP receptor complex, glutamate receptors, salicylic acid-biosynthesis enzyme, or glutamate decarboxylase. In addition, Glu also enhances PAMP-inducible immune responses, such as production of reactive oxygen species and mitogen-activated protein kinase activation. These results show that Glu activates PAMP/DAMP-triggered immunity signaling pathway in a novel manner.

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).

Project description:The project intended to reveal protein phosphorylation patterns in Arabidopsis thaliana in response to ATP. For this purpose, Arabidopsis thaliana plants, including WT, ATP receptor mutants (p2k1, p2k2, and double mutant p2k1/p2k2), and P2K1 overexpression plants, were treated with ATP or buffer (as the negative control). Crude membrane proteins were then extracted, reduced with DTT, alkylated with iodoacetamide, and digested with Lys-C/trypsin. The digested peptides were then acidified with formic acid, desalted with C18 SPE columns, and concentrated in a Speed-Vac concentrator. The Phosphopeptides were enriched from the above digested peptide samples using IMAC and then analyzed with LC-MS/MS. Data was searched with MaxQuant (ver. 2.0.1.0), which identified and quantified peptides and proteins across all of with Arabidopsis thaliana data set (Uniprot.2020.11.02).

Project description:The aim of this study was to analyze the impact of autotetraploidy on gene expression in Arabidopsis thaliana by comparing diploid versus tetraploid transcriptomes. In particular, this included the comparison of the transcriptome of different tetraploid A. thaliana ecotypes (Col-0 vs. Ler-0). The study was extended to address further aspects. One was the comparison of the transcriptomes in subsequent generations. This intended to obtain information on the genome wide stability of autotetraploid gene expression. Another line of work compared the transcriptomes of different diploid vs. tetraploid tissues. This aimed to investigate whether particular gene groups are specifically affected during the development of A. thaliana autotetraploids. Samples 1-8: Arabidopsis thaliana Col-0 tetraploid transcriptome. Transcriptional profiling and comparison of diploid vs. tetraploid Col-0 seedlings. The experiment was carried out with pedigree of independently generated and assessed tetraploid Col-0 lines. Samples 9-12: Arabidopsis thaliana Ler-0 tetraploid transcriptome. Transcriptional profiling and comparison of diploid vs. tetraploid Ler-0 seedlings. The experiment was carried out with pedigree of independently generated and assessed tetraploid Ler-0 lines. Samples 13-24: Arabidopsis thaliana Col-0 tetraploid transcriptome. Transcriptional profiling and comparison of diploid vs. tetraploid Col-0 leaves (6th - 8th).
