During evolution, the acquisition of special types of cells and tissues requires new regulatory genes that control cell division and cell differentiation. Here, we found that stomatal basic helix-loop-helix (bHLH) transcription factors are co-opted for the development of seta in the liverwort Marchantia polymorpha, which lacks true stomata.
