  1. Data sets used: 1. Zygnematophyceae and 12 Spirogyra sequences (same as in combined SSU alignment used in Figure 1). 2. Zygnematophyceae. 3. All Spirogyra sequences (same as Spirogyra alignment used in Figure 2). 4. 12 Spirogyra sequences (same Spirogyra sequences as data set 1.). 5. Zygnematophyceae without Spirotaenia. 6. Spirotaenia.
