Abstract
<div><p>Background</p><p>Filamentous Zygnematophyceae are typical components of algal mats in the polar hydro-terrestrial environment. Under field conditions, they form senescent vegetative cells, designated as pre-akinetes, which are tolerant to desiccation and osmotic stress.</p><p>Key Findings</p><p>Pre-akinete formation and desiccation tolerance was investigated experimentally under monitored laboratory conditions in four strains of Arctic and Antarctic isolates with vegetative <i>Zygnema</i> sp. morphology. Phylogenetic analyses of <i>rbc</i>L sequences revealed one Arctic strain as genus <i>Zygnemopsis</i>, phylogenetically distant from the closely related...
