From: Hidden genetic diversity in the green alga Spirogyra (Zygnematophyceae, Streptophyta)
Putative secondary structure model of the nuclear encoded SSU rRNA of Spirogyra sp.; Strain WRH5 (Acc.No. JQ 239088) from Clade B was chosen as representative sequence; 100% consensus bases for the genus Spirogyra are given in upper case letters, variable positions in lower case letters; NHS for Spirogyra are marked with blue circles, NHS for one of the clades are marked by green circles, the assigned number indicates the number in the table; see Additional file 4: Table S4 for details.
