Sexual reproduction by conjugation characterizes the genus Spirotaenia, and based on this character alone it has long been considered a member of the class Zygnematophyceae (Streptophyta). The similarity in chloroplast morphology between the unicellular Spirotaenia (Mesotaeniaceae) and the filamentous Spirogyra (Zygnemataceae) has led to the assumption that the two genera are evolutionarily related, a view apparently supported by rbcL sequence comparisons (McCourt et al. 2000). We sequenced the… CONTINUE READING
