Latent genetic potential (LGP) in the protein building blocks for plant terrestrialization. (a) Phylogenetic distribution of key protein domains contributing to 96 stress-relevant orthogroups described in land plants. The bubble plot shows: (i) the 37 species/datasets on the x-axis; (ii) the 96 orthogroups and their corresponding functional annotations on the y-axis; (iii) presence (big circle) or absence (small circle) of embryophytic domains pertaining each orthogroup, and (iv) the count (log₂-transformed) of proteins within each orthogroup, from black (absent) to white (highest). (b) Word cloud showing the top 50 most frequent Gene Ontology (GO) annotations (‘Biological Function’ via eggNOG-mapper) for proteins from the 96 orthogroups at the LCA of land plants node (node a in figure 2d). Word size represents GO term frequency.
