Two antagonists of "normal" proline-hydroxyproline-protein synthesis, 2,2'-dipyridyl and hydroxy-L-proline, induced the same kind of phenovariation in Nowellia curvifolia (Dicks) Mitt. (Cephaloziaceae) as they do in Scapania nemorosa (Scapaniaceae). This finding supports a hypothesized cardinal role for proline-hydroxyproline-protein in modulating aspects of morphogenesis and phylogeny in the leafy liverworts.
