摘要 About 500?million years ago (Ma) land plants emerged (Morris et?al., 2018). This was one of the most transformative events in Earth’s history, giving rise to an astonishing diversity of species that formed complex plant-dominated ecosystems. The earliest land plants, therefore, needed to respond to the myriad of terrestrial stressors posed by the new environment. Perhaps the most obvious ones are those related to water availability, that is reduced access to water and increased water loss by drought and temperature stress. Stomata are a key trait of land plants; roots and vascular tissue further facilitated these adaptations, underpinning the success of Tracheophyta. These systems allow the active and more efficient absorption and transport of water and the regulation of its evaporation. In a recently published article in New Phytologist, Bowles et?al. (2022; doi: 10.1111/nph.17981) use available genomic and transcriptomic data across all major lineages of streptophytes to paint a picture of the evolutionary history that shaped the molecular toolkit required to develop and operate roots, vascular tissue and stomata.
