In diploid organisms, selfing reduces the efficiency of selection in purging deleterious mutations from a population. This need not be the case for all organisms. Some plants, for example, undergo an extreme from of selfing known as intragametophytic selfing, which immediately exposes all recessive deleterious mutations in a parental genome to selective purging. Using the transcriptome data from S. subsecundum, S. cribrosum and 2 other previously published moss transcriptome, we ask how effectively deleterious mutations are purged from such plants. Specifically, we study genome-wide signatures of selective purging in the transcriptomes of four moss species that differ in their incidence of selfing and outcrossing.
