Only when aggregated as a biofilm, the algal mat becomes visible to the naked eye in dunes along the Baltic Sea or Arctic tundra.<\/p>\n<p>Streptofilum capillatum itself was first described by the same team just a few years ago from agricultural soil and represents a new lineage in the plant evolutionary tree. Remarkably, this alga is an evolutionary precursor to modern plants and can be considered a living fossil.<\/p>\n<p>Streptofilum belongs to the most primitive algal representatives within the streptophyte lineage, which is directly related to land plants. It originates from the era when freshwater algae colonized land. Evolutionary innovations were necessary to survive terrestrial challenges such as drought, extreme temperature fluctuations, and UV radiation. These adaptations ultimately gave rise to plants.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Cell_functions_protect_algae_from_drought\"><\/span>Cell functions protect algae from drought<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>&#8220;These algae potentially have an exceptionally flexible cell wall, which differs significantly in fine structure from those of other green algae. We demonstrated this using electron microscopy. During water scarcity, the cell wall shrinks; when water is available again, the wall expands, allowing the cell to rehydrate without damage. This function explains the evolutionary transition of these algae from water to land,&#8221; explains Junior Professor Karin Glaser from the Institute of Bio<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/sciencee\/\" data-internallinksmanager029f6b8e52c=\"5\" title=\"Science\" target=\"_blank\" rel=\"noopener\">science<\/a>s at TU Bergakademie Freiberg.<\/p>\n<p>The cell functions also enable Streptofilum to adapt to extreme environmental conditions. The algae survive in dry, cold Arctic soils and can reactivate rapidly after droughts. They are also remarkably resilient to light and temperature, thriving under both low light and intense UV radiation, with a temperature tolerance range of 5\u00b0C to 40\u00b0C. This allows the algae to tolerate climate fluctuations and makes them likely to withstand future challenges.<\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2025\/team-investigates-cell.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2025\/team-investigates-cell.jpg\" data-sub-html=\"The team has detected the new algae species on the Baltic Sea coast, among other places.

For example, algae-derived UV-resistant compounds could be developed for eco-friendly sunscreens that avoid harming corals and marine ecosystems, unlike current chemical ingredients.<\/p>\n<p>&#8220;These algae produce mycosporine-like amino acids, which protect them from UV radiation.
