Hidden genetic diversity in the green alga Spirogyra (Zygnematophyceae, Streptophyta).

BMC evolutionary biology - 1 Jun 2012

Abstract excerpt

BACKGROUND: The unbranched filamentous green alga Spirogyra (Streptophyta, Zygnemataceae) is easily recognizable based on its vegetative morphology, which shows one to several spiral chloroplasts. This simple structure falsely points to a low genetic diversity: Spirogyra is commonly excluded from phylogenetic analyses because the genus is known as a long-branch taxon caused by a high evolutionary rate. RESULTS:...
