Deep genetic structure within the Zygnematophyceae is revealed by 104 transcriptomes and 2243 loci, showing major divergence between Spirogyrales and Desmidiales and later Spirogyrales diversification.
- Why it matters: Clarifying the last common ancestor of land plants depends on understanding their closest algal relatives, but limited phylodiverse genomic sampling has constrained views of divergence and trait potential.
- What they did: The study generated 43 new Zygnematophyceae transcriptome datasets and inferred a phylogenomic tree using 104 transcriptomes and 2243 loci to resolve lineage relationships and divergence patterns.
- The result: It finds that most Spirogyrales emerged after pronounced genetic divergence, aligning with multicellularity and divergent cell and plastid division traits, and it reveals massive ancient radiations enabled by phylodiverse sampling.
