PEATmoss is an interactive gene expression atlas for bryophytes, which originally unified Physcomitrium patens RNA-seq and microarray expression data from multiple gene annotation versions. This atlas includes more than 100 experiments of P. patens, is expanding to host Anthoceros agrestis and Marchantia polymorpha, and aims to host data from more species in the future. PEATmoss has multiple visualization methods and tools for data downloading and is connected to the Physcomitrium patens Gene Model Lookup DB (PpGML DB), which links P. patens genes to annotations and resources from several databases and contains tools for gene version lookup and sequence and annotation extraction. Among the new features available in PEATmoss are dataset privacy control, multispecies menu, interactive color scale, co-expression network visualization, and replicate data downloading.
