The liverwort Marchantia polymorpha is an emerging model organism on account of its ideal characteristics for molecular genetics in addition to occupying a crucial position in the evolution of land plants. Here we describe a method for gene targeting by applying a positive/negative selection system for reduction of non-homologous random integration to an efficient Agrobacterium-mediated transfo...

Sex of the liverwort Marchantia polymorpha is determined by the sex chromosomes Y and X, in male and female plant, respectively. Approximately half of the Y chromosome is made up of unique repeat sequences. Here, we report that part of the Y chromosome, represented by a 90-kb insert of a genomic clone pMM2D3, contains five putative genes in addition to the ORF162 gene, which is present also wit...
