A Year at the Forefront of Streptophyte Algal Evolution.

Land plants originated from an algal ancestor ∼500 million years ago in one of the most important evolutionary events for life on Earth. Extant streptophyte algae, their closest living relatives, have subsequently received much attention to better understand this major evolutionary transition. Streptophyte algae occupy many different environments, have diverse genomes and display contrasting morphologies (e.g. unicellular, filamentous, three-dimensional). This has historically made inferring these evolutionary events challenging. This A Year at the Forefront Review focusses on research published between July 2023 and June 2024 and intends to provide a short overview of recent discoveries, innovations, resources, and hypotheses regarding streptophyte algal evolution. This work has provided mechanistic insights into ancient evolutionary events that prefigured the origin of land plants and raises new questions for future research into streptophyte algae.
