Contains 3D structural data sets done with X-ray ptychographic CT (PXCT) and X-ray nanoholotomograhy (XNH). Contains also trace elemental 2D slices of the roots, made with X-ray nanofluorescence CT imaging (XRF). The roots received 3 different treatments: control, Se treated, and Se+bacterial treated. This data set is related to the paper by Hanna Help et al. titled "High-resolution synchrotron imaging for studying micronutrient uptake in intact fresh roots " (https://doi.org/10.1101/767558 ) The data labels for PXCT data / treatment: id_131: control #1 id_132: Se + bacteria #1 id_133: Se (failed) id_134: Se + bacteria #2 id_135: control #2 (failed a bit) id_136: Se The data labels for XNH and XRF data / treatment: E1D_001: control E2B_001: Se #1 E2B_002: Se #2 E2C_002: Se #3 E3B_001: Se + bact #1 E3X_001: Se + bact #2 E3X_002: Se + bact #3
