Summary Auxin is a signaling molecule that regulates multiple processes in the growth and development of land plants. Research gathered from model species, particularly Arabidopsis thaliana , has revealed nuclear auxin pathway controls many these through transcriptional regulation. Recently, non-transcriptional based on rapid phosphorylation mediated by kinases been described, complementing understanding complexity auxin-regulated processes. Phylogenetic inferences both pathways indicate only some components are conserved beyond This raises fundamental questions about evolutionary origin responses whether algal sisters share mechanistic features with Here we explore unicellular streptophyte alga Penium margaritaceum . By assessing physiological, transcriptomic cellular found triggers cell proliferation, gene regulation acceleration cytoplasmic streaming. Notably, all also triggered structurally related tryptophan. These results identify shared response among plants algae, suggest less chemically specific preceded emergence auxin-specific regulatory networks
