Project description:Potato seedlings were subjected to cold, heat and salt stress. Expression profiles were captured at three different time-points, 3h, 9h and 27h from two different tissues, roots and leaves. The experiment was preformed independently three times. Commercially available true potato seeds (Variety Gilroy) were germinated on rafts floating on hydroponic medium in Magenta boxes. Plants were grown for 5 weeks prior to stress application under long day conditions (16h light and 8h dark) at 25C with gentle agitation. To initiate stress the medium was replaced with fresh medium pre-chilled to 4C (cold stress), pre-heated to 35C (heat stress) or supplemented with 100mM NaCl (salt stress). Cold and heat stress were maintained for the duration of the experiment by placing the Magenta boxes on ice or in a water-bath at 35C. For every individual sample two boxes of plants were used pooling a total of 6 plants per sample. For each time-point a single control sample was used by changing the media in a similar way as for the stress induction. A total of six boxes were combined for the pooled reference samples. Plants were harvested at the appropriate time and snap-frozen in liquid nitrogen. Roots and aerial tissue was separated prior to freezing. The tissue was stored at -80C freezer until isolation. Total RNA was isolated using RNeasy isolation kit. The intactness of the RNA was verified on gel and the concentration was adjusted to 3ug/ul by ethanol precipitation and re-suspension.

Project description:The mkkkC5 mutant, a knockout line of MAPKKKC5, shows changes in growth and development, as well as an altered Alternaria sensitivity. It was shown by Brader and Djamei et al.(2007) that Alternaria brassicicola sensitivity is also influenced by MKK2-activity. Aim of this experiment is to access the transcriptional changes in the mkkkc5plants as well as in plants overexpressing a constitutively active MKK2-version (MKK2EE). The second part of the experiment addresses transcriptional changes in these plants after Alternaria brassicicola infection. au07-09_alternaria Keywords: treatment variations

Project description:Plants have a wide variety of ways to defend against pathogens. To assist efforts to counter severe losses of Solanum tuberosum (potato) yields caused by various pathogens, we have studied immune responses of potato plants using quantitative proteomic techniques. We have combined protein isolation and subcellular fractionation to identify proteins that change in abundance during the immune response. This dataset contains the analysis of subcellular fraction 2 of our experiment. In a previous analysis, another fraction was analyzed using a different methodology. For this reason, the two datasets are submitted separately.

Project description:Background: Alternaria exposure is associated with severe asthma in humans. Alternaria exposure in mice potently activates group 2 innate lymphoid cells (ILC2s) via the IL-33/ST2 axis and causes ILC2s to robustly secrete type 2 cytokines. Objective: Our aim was to determine whether conventionally used ILC2 markers, ST2 (IL-33R) and CD127 (IL-7Ra), were sufficient to identify all Th2-cytokine producing ILCs after Alternaria exposure. Methods: Mice received intranasal Alternaria for three days prior to analysis. Lung ILCs were identified by flow cytometry as CD45+Lineage−Thy1.2+ lymphocyte-sized cells, divided into four subsets based on ST2 and CD127 expression, and stained for intracellular cytokines and transcription factors. Sort-purified ILC subpopulations were also analyzed by RNA sequencing and qPCR. Results: Alternaria exposure led to accumulation of all ILC populations regardless of ST2 or CD127 expression. Nearly half of the GATA-3+, IL-5+, and IL-13+ ILCs were “unconventional” as they were either single or double negative for ST2/CD127. Further, these populations upregulated CD25, KLRG1, and ICOS after Alternaria challenge. Some activated unconventional IL-5+ ILC2s also produced IFNγ and IL-17A. In addition to shared ILC2 transcripts (Gata3, Il5, Il13) in all populations, RNA-seq further identified novel transcripts enriched in each subset. Finally, transcripts from all populations that correlated best with IL-5 and IL-13 production included Tnfrsf18, Ffar2, and Pde4b. Conclusions: Unconventional ST2- and CD127-negative mouse lung ILC2 populations are induced by Alternaria. Thus, commonly used lung ILC2 identification methods based on ST2 and CD127 do not accurately account for the total ILC2 burden and may exclude nearly half of these cells.
