Mayerhofer et al (2021) "Recently photoassimilated Carbon and fungus-delivered Nitrogen are spatially correlated at the cellular scale in the ectomycorrhizal tissue of Fagus sylvatica", The New Phytologist, DOI:10.1111/nph.17591

It contains the following data:

(1) NanoSIMS imaging data, which was used for Fig. 4-7, is provided in NanoSIMS_control_root_tip.zip and NanoSIMS_labelled_root_tip.zip. Each zip-files contains:

• the original NanoSIMS images (.im)
• their related checkfiles (.chk_im)
• ROIs description (.rois.zip)

of the unlabelled control and the labelled root tip section, respectively. ".im" and ".chk_im" are the original image data aquisition files from the NanoSIMS instrument. "rois.zip" files describe selected regions of interests and were created utilizing the OpenMIMS plugin (Center for Nano Imaging, https://nano.bwh.harvard.edu/MIMSsoftware) for the image analysis software ImageJ (National Institutes of Health, Bethesda, MD, USA).

(2) Means and standard deviations of all measured elements and isotopes of each region of interest, as obtained via the .rois.zip files from the NanoSIMS images, are reported in NanoSIMS_ROI_data.csv (used for Fig.7).

(3) Linescan_data.csv contains data used for Fig. 8.

(4) IRMS_roots_data.csv contains data of root segments and mycorrhizal root tips analysed with isotope-ratio mass spectrometry (EA-IRMS) (used for Fig. 2)

Description of column meanings from csv data files can be found in the according "_description" files.
