|a The moss Physcomitrium patens is a model system for the evolutionary study of land plants, and as such, it may contain as yet unannotated genes with functions related to the adaptation to water deficiency that was required during the water-to-land transition. In this study, we identified a novel gene, Bryophyte Co-retained Gene 1 (BCG1), in P. patens that is responsive to dehydration and rehydration. Under de- and rehydration treatments, BCG1 was significantly co-expressed with DHNA, which encodes a dehydrin (DHN). Examination of previous microarray data revealed that BCG1 is highly expressed in spores, archegonia (female reproductive organ), and mature sporophytes. In addition, the bcg1 mutant showed reduced dehydration tolerance, and this was accompanied by a relatively low level of chlorophyll content during recovery. Comprehensive transcriptomics uncovered a detailed set of regulatory processes that were affected by the disruption to BCG1. Experimental evidence showed that BCG1 might function in antioxidant activity, the abscisic acid pathway, and in intracellular Ca2+ homeostasis to resist desiccation. Overall, our results provide insights into the role of a bryophyte co-retained gene in desiccation tolerance
