Research Abstract

Infection assays were carried out using Nostoc culture strains of both free-living and symbiotic origins in order to examine host-symbiont (non-)specifity in the association between diazotrophic cyanobacteria and plants. Molecular phylogenetic, physiological and developmental analyses of the Nostoc species were integrated to discuss evolutionary process of diversity and specifity of plant hosts for cyanobionts.
