Abstract
Chloroplasts develop from undifferentiated plastids in response to light. In angiosperms, after the perception of light, the Elongated Hypocotyl 5 (HY5) transcription factor initiates photomorphogenesis, and two families of transcription factors known as GOLDEN2-LIKE (GLK) and GATA are considered master regulators of chloroplast development. In addition, the MIR171-targeted SCARECROW-LIKE GRAS transcription factors also impact chlorophyll biosynthesis. The extent to which these proteins carry out conserved roles in non-seed plants is not known. Using the model liverwort Marchantia polymorpha, we show that GLK controls chloroplast biogenesis, and HY5 shows a small conditional effect on chlorophyll content. Chromatin immunoprecipitation sequencing (ChIP-seq) revealed that MpGLK has a broader set of targets than has been reported in angiosperms. We also identified a functional GLK homolog in green algae. In summary, our data support the hypothesis that GLK carries out a conserved role relating to chloroplast biogenesis in land plants and green algae.
