To generate a comprehensive cell atlas of the model plant Arabidopsis with biological focus on leaf senescence and nutrient allocation, we collected 20 tissues that represent the key developmental stages and transitions throughout the entire life cycle, including two stages of root (6d and 11d after germination), shoot at 6d (cotyledon, SAM and leaf primordia), six stages of the second pair of true leaves (rosette) from expansion to senescence (from 14 to 49d, with 7-day interval), inflorescence stem (apical, middle and basal regions) at 42d, cauline leaf at 42d, three stages of flowers (flower bud to fully opened flowers) at 49d and six successive timepoints of siliques (0 to 5d after anthesis with 1-day interval). To facilitate further exploration of our single-nucleus Arabidopsis atlas, we have deposited the snRNA-seq raw data (https://db.cngb.org/search/project/CNP0002614/) and gene metrics (https://ftp.cngb.org/pub/CNSA/data6/CNP0002614/Other/) in the CNGBdb database under accession number CNP0002614.
