FIGURE 2.

Comparing shoot development across model land plants. Comparison of shoot characteristics found in the gametophyte (pink) and sporophyte (blue) generations of select developmental/genetic model plant species, including examples from most extant land plant (embryophyte) lineages. Broader clade denominations between these lineages are indicated by green bars above (see Figure 1). It should be noted that not all model species are entirely representative of development within each lineage, in particular the mosses and liverworts. Examples from other species and fossil data are included in this review where necessary to provide a more accurate representation of evolutionary trajectories.
