The role of c-di-GMP in biofilm formation of the filamentous cyanobacterium Nostoc punctiforme
The signaling molecule c-di-GMP is a ubiquitous second messenger in bacterial species including cyanobacteria. C-di-GMP stimulates the biosynthesis of extracellular polymeric substances (EPS) in biofilms and regulates the transition between a motile and a sessile life style in many bacteria. In our study we focus on c-di-GMP function and EPS production associated with biofilm Formation in Nostoc punctiforme, which is known to produce EPS in biofilms and liquid culture.

Snapshots of fungal extracellular matrices
Fungal extracellular materials reinforce a constant interaction between their cell wall and the environment. A dynamic mixture of chitin, glucans, mannans, glycoproteins, glycolipids and pigments supports the success of all fungal life styles – from symbiotic to the free-living and pathogenic. Fungi are perfectly adapted to grow on surfaces and in porous environments, where they form medically and geochemically relevant biofilms. Fungal EPS are critical in adhesion to other fungi, other cells or substratum as well as in the following interaction with the host immune system or material they attack, degrade and deteriorate respectively. Characterisation of extracellular compounds and understanding of its function is necessary to limit damage caused by fungal activity. All necessary methodology from chemical characterization to complete genetic analyses has been developed for medically important fungi. Now it is time to apply this knowledge to the numerous, largely aerobic and very active organisms that occupy a wide range of atmosphere-exposed habitats in the upper lithosphere. One can expect that analogies between medically- and environmentally-relevant model fungal species will help us to address the dynamics of the fungal cell EPS matrix in much more efficient and widely applicable ways.
