Project description:The overall objective was to document transcriptomic changes in the guard cells of Arabidopsis thaliana under short (1x) - and long-term (3x) saline growth conditions. Guard cells of Arabidopsis responded also to the intensity of the salt management by the microarray datasets clearly clustering in (-) salt, 1x salt and 3x salt. Similarly, more GO terms were significantly enriched in differentially expressed guard cell genes of 1 x salt than 3x salt treated plants.
Project description:Microbes of the root-associated microbiome contribute to improve resilience and fitness of plants. In this study, the interaction between the salt stress tolerance-inducing beneficial bacterium Enterobacter sp. SA187 and Arabidopsis was investigated with a special focus on the plant immune system. Among the immune signalling mutants, the Lys-motif receptors LYK4 strongly affected the beneficial interaction. Overexpression of the chitin receptor components LYK4 compromised the beneficial effect of SA187 on Arabidopsis. Transcriptome analysis revealed that the role of LYK4 in immunity is intertwined with a function in remodeling defense responses. Overall, our data indicate that components of the plant immune system are key elements in mediating beneficial metabolite-induced plant abiotic stress tolerance.
