Teaching an old liverwort some new tricks- developmental genetics and genomics of Marchantia polymorpha.
The last few years have seen the sequencing of non-flowering genomes of a moss and a lycophyte allowing unprecedented genome-wide comparisons among land plants. The ability to transform the moss Physcomitrella combined with a sequenced genome has begun to produce insights into developmental genetics of a haploid dominant plant. Marchantia polymorpha is a liverwort with a long history as the subject of a wide range of studies as well as an organism familiar to almost every biology student. Marchantia is a representative of the sister clade to all other land plants and thus holds a key position for comparative genetics and genomics. We are working with colleagues to develop this plant as a phylogenetically significant tool for developmental genetics and comparative genomics. Many aspects of Marchantia biology make it an ideal model organism. I will present some of our results utilizing genetic transformation to understand the function of some key transcription factors such as Class III HD-Zip genes and genes associated with auxin biology to demonstrate the great promise of Marchantia for understanding land plant developmental evolution.
