Changing temperature is a common abiotic stress for land plants. Based on large-scale gene expression analyses we characterized the whole-genome transcriptomic cold stress response of Physcomitrella patens in correlation with phenotypic and metabolic changes. While transcription associated protein-encoding gene families show a global specialization, 12 % of the 3,220 differentially expressed genes are orphan genes that may contribute to moss-specific signalling and cold tolerance.
