“…To further understand the transcriptional regulatory sequences underlying accessible chromatin in distinct cell identities, we performed global motif enrichment analysis across all accessible chromatin regions specific to each cell. Enrichment of motif sequences in accessible chromatin regions relative to background (motif deviation scores) for known regulators were consistent with the predicted cell identities, including WRKY family TFs in the specification of root epidermal progenitors (Marand et al, 2021), MYB in endodermis, cortex and pericycle (Cohen et al, 2020), ULT1…”

“…thaliana root scATAC-seq data sets generated using the commercial 10X Genomics Chromium platform (Farmer et al, 2021;Marand et al, 2021). We uniformly processed all libraries to demultiplex reads, assign cell barcodes, align fragments to the TAIR10 reference genome, remove duplicated fragments, and use the R package Socrates to analyze all three data sets (Methods).…”

“…Single-cell RNA-seq has also moved beyond Arabidopsis, with studies emerging for tomato 26 , rice 27 , maize [28][29][30][31] , and moss 32 . Beyond single-cell RNA-seq, epigenomic profiling afforded by single-cell ATAC-seq has become increasingly used in plants [33][34][35] and is ideally suited to explore gene regulation, elucidate regulatory networks, and even more finely classify cell types. scRNA-seq and scATAC-seq datasets are highly complementary and can be combined effectively 34 .…”

“…Examples of these approaches include computational strategies to capture "free" information from existing data, including developmental trajectories (e.g., Monocle 71 , Palantir 72 , SlingShot 73 , and CellRank 74 ), RNA dynamics (e.g., RNA velocity 75 and scVelo 76 ), methods to integrate disparate and multimodal datasets (e.g., Seurat 77 , Harmony 78 , Symphony 79 ), methods that implement differential gene expression analysis (e.g., MILO 80 ), and several end-to-end pipelines that implement large collections of tools in a single computational ecosystem (e.g., Seurat 81 , Monocle 71 , scanpy 82 ). While many of the tools already developed for analysis of single-cell data from mammalian tissues will be applicable to analysis of plant data sets, and indeed some tools were specifically developed for the analysis of plant singlecell data (e.g., Asc-Seurat 43 , COPILOT 20 , Socrates 33 ), several computational challenges remain that are unique or of particular consideration to plants and would benefit from the development of still more new tools and databases. For example, as research moves from Arabidopsis roots in the first wave of studies to new species and tissues, how do we know if cell clusters represent true cell types if no high-quality cell type-specific markers are already known?…”
