Rhodotorula toruloides Nitrogen Limitation PTM Profiling Multi-Omics (TZ-DP1)
The purpose of this experiment was to evaluate the regulatory stress response of Oleaginous yeast species Rhodotorula toruloides NBRC 0880 (JGI strain IFO0880 v4.0) under nitrogen-rich and nitrogen-limited conditions over time. Time course experimental samples (0, 24, 48, and 72 hours after inoculation) were prepared using a semi-automated multi-PTM proteomic approach, using tandem mass tag 18-plex (TMT18), and lipidome remodeling for downstream multi-omics analysis.
Accessible Digital Data Downloads*
Processed datasets are openly accessible from the download button and contain secondary processed proteomic (redox, phospho, and global TMT) and lipidomic (positive and negative ion mode) results files and experimental design metadata. Experimental proteomic sample data was acquired using an Orbitrap Exploris 480 mass spectrometer and processed and compiled using PlexedPiper software workflow and custom R. toruloides Nitrogen Limitation Multi-PTM Profiling R Package (located at Zenodo). Experimental lipidomic sample data were collected in parallel with proteomic samples and acquired using an Orbitrap Fusion Lumos mass spectrometer and further processed using MS-DIAL, lipidr R package, and MetaboAnalyst 6.0 software. Processed data package download includes sample naming keys, raw abundance files, sequence annotations, and supporting metadata materials.
