Streptophyte algae are the closest relatives to land plants; their latest common ancestor performed the most drastic adaptation in plant evolution around 500 million years ago: the conquest of land. Besides other adaptations, this step required changes in cell wall composition. Current knowledge on the cell walls of streptophyte algae and especially on the presence of arabinogalactan-proteins (AGPs), important signalling molecules in all land plants, is limited.

As the sister lineage to seed plants, knowledge on the cell wall of ferns is key to track evolutionary changes across tracheophytes and to understand seed plant-specific evolutionary innovations. Fern cell wall composition is not fully understood, including limited knowledge of glycoproteins such as the fern arabinogalactan proteins (AGPs).

- The transition from freshwater to land was crucial for plant diversification, with bryophytes and vascular plants sharing a common ancestor that adapted to terrestrial life.
- This review examines the polysaccharide-rich cell walls of hornworts and liverworts, highlighting both shared traits and unique structural characteristics between them and vascular plants.
- The findings emphasize the need for further research on cell wall structures to better understand the evolution of bryophytes and their adaptations to land environments.
