Abstract excerpt

Sigma factor is a subunit of plastid-encoded RNA polymerase that regulates the transcription of plastid-encoded genes by recognizing a set of promoters. Sigma factors have increased in copy number and have diversified during the evolution of land plants, but details of this process remain unknown. Liverworts represent the basal group of embryophytes and are expected to retain the ancestral features of land...
