Arabidopsis thaliana proteome in response to cysteine treatment and Pseudomonas syringae pv. tomato DC3000

ABSTRACT: The amino acid cysteine was repeatedly shown to be implicated in the plants stress response. This project aims to elucidate which effect cysteine has on the proteome of Arabidopsis. Treatment of Arabidopsis thaliana seedling cultures with cysteine resulted in distinct proteomic changes. To further investigate on the role of cysteine metabolism and associated proteins during biotic stress, the proteomic response of Arabidopsis thaliana leaves inoculated with the plant pathogen Pseudomonas syringae pv. tomato DC3000 was monitored.

The amino acid cysteine is the precursor for a wide range of sulfur-containing functional molecules in plants, including enzyme cofactors and defence compounds. Due to its redox active thiol group cysteine is highly reactive. Synthesis and degradation pathways are present in several subcellular compartments to adjust the intracellular cysteine concentration. However, stress conditions can lead to a transient increase in local cysteine levels. Here we investigate links between cysteine homeostasi  ...[more]
