Project description:Arabidopsis sfr mutants are deficient in cold acclimation during exposure to coolnon-freezing temperatures. Although not visibly affected by the cold they have lost the ability to survive subsequent freezing. We plan to investigate how the sfr2 and sfr6 mutants respond to low temperature on the gene expression level. Wild type plants that have undergone identical treatments in parallel are necessary controls. The cold treatment of plants in the rosette stage (soil grown in a 8/16 hours day/night cycle) will be carried out in a cooled growth chamber at 4 degrees for 24 hours (same light regimetreatment starting/ending at the 4th hour of light). The aerial parts of the treated and untreated plants will be collected and frozen immediately in liquid nitrogen for RNA extraction. Comparison of the cold response of thousands of Arabidopsis genes in the wild type to the situation in our freezing sensitive mutants will enhance our understanding of the cold response itself and illuminate the effect of the mutations on the cold acclimation process.

Project description:Abiotic stress exposure of plants induces metabolic reprogramming which is tightly regulated by signalling cascades connecting transcriptional with translational and metabolic regulation. Complexity of such interconnected metabolic networks impedes the functional understanding of molecular plant stress response compromising the design of breeding strategies and biotechnological processes. Thus, defining a molecular network to enable the prediction of a plant’s stress mode promises to promote the understanding of stress responsive biochemical regulation and its technological application. Arabidopsis wild type plants and two mutant lines with deficiency in sucrose or starch metabolism were grown under ambient and cold/high light stress conditions. Stress-induced dynamics of the primary metabolome and the proteome were quantified in a mass spectrometry-based high-throughput experiment. Wild type data were used to train a machine learning algorithm to classify mutant lines under control and stress conditions. Multivariate analysis and classification identified a module consisting of 23 proteins enabling the reliable prediction of coupled temperature and light stress conditions. 18 of these 23 proteins displayed putative protein-protein interactions connecting transcriptional regulation with regulation of primary and secondary metabolism under stress. The identified stress-responsive core module provides evidence for predictability of complex biochemical regulation during environmental fluctuation.

Project description:How bacteria from the microbiota modulate the physiology of its host is an important question to address. Previous work revealed that the metabolic status of Arabidopsis thaliana was crucial for the specific recruitment of Streptomycetaceae into the microbiota. Here, the Arabidopsis-Actinacidiphila interaction was further depicted by inoculating axenic Arabidopsis with Actinacidiphila cocklensis DSM 42063 or Actinacidiphila bryophytorum DSM 42138(previously named Streptomyces cocklensis and Streptomyces bryophytorum). We demonstrated that these two bacteria colonize A. thaliana wild-type plants, but their colonization efficiency was reduced in a chs5 mutant with defect in isoprenoid, phenylpropanoids and lipids synthesis. We observed that those bacteria affect the growth of the chs5 mutant but not of the wild-type plants. Using a mass spectrometry-based proteomic approach, we showed a modulation of the Arabidopsis proteome and in particular its components involved in photosynthesis or phytohormone homeostasis or perception by A. cocklensis and A. bryophytorum. This study unveils specific aspects of the Actinacidiphila-Arabidopsis interaction, which implies molecular processes impaired in the chs5 mutant and otherwise at play in the wild-type. More generally, this study highlights complex and distinct molecular interactions between Arabidopsis thaliana and bacteria belonging to the Actinacidiphila genus.
