Plant genomes produce a myriad of noncoding RNAs (ncRNAs), including long ncRNAs (lncRNAs) that are classically >200 nucleotides in length and show no discernable coding potential^[1]. Emerging evidences have shown that lncRNAs are widely expressed and play important roles in various biological processes, such as gene expression regulation, genomic imprinting, plant growth and development as well as stress responses^[1,2,3]. To decode the lncRNA-associated GRNs that regulate cell-type specific gene expression in plants, we compiled a catalog of 24848 lncRNAs from recent studies and generated a comprehensive compendium of single cell transcriptomic data by integrative analysis of 28 published single cell RNA-sequencing (scRNA-seq) datasets in Arabidopsis juvenile seedlings. scPLAD is a single cell-based browser of these Plant lncRNA atlas.
