As oxygen-producing photoautotrophs, cyanobacteria have been, and continue to be, one of the most influential groups of micro-organisms on earth. They are an ancient lineage, with a fossil record dating to at least 3 billion years ago and were singularly responsible for the initial oxygenation of the biosphere. Cyanobacteria are the most nutritionally independent organisms on earth, requiring only light, water, CO2 and a few inorganic molecules or elements for growth; some can fix nitrogen. They areubiquitous in the illuminated portions of the terrestrial and aquatic biosphere, including deep oceanic, hypersaline, geothermal, desert and polar habitats, as well as being endolithic and endophytic. Cyanobacteria display diverse cellular and colonial morphologies, cellular developmental alternatives, types of secondary metabolites, some of which are toxic to metazoans, and behaviors, such as chromatic adaptation, reversible desiccation and genetic adaptation to environmental changes. Molecular genetic evidence is consistent with a common cyanobacterial ancestor giving rise to the chloroplasts of eukaryotic algae and plants. Processes and pathways expressed by extant cyanobacteria, such as circadian rhythms, phytochrome signaling and cellulose synthesis, amongst others, are likely to have entered the plant world via that ancient endosymbiotic event. Many cyanobacteria are amenable to genetic manipulation; therefore, they are excellent experimental systems for studies of photosynthetic and nitrogen metabolism, regulation of the differentiation of specialized cells, cell-cell communication and environmental signal transduction. The genomes of more than 190 cyanobacteria have been sequenced to date and genomic based analyses are being applied to document their changing transcriptome, proteome and metabalome. In this special issue, advanceswill be presented in understanding the ecology, physiology and genetics of cyanobacteria, using classic and molecular genetic approaches that will ultimately aid inmanipulation of selected organisms for biotechnological applications in bioremediation, biofuel and pharmaceutical production.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Life is an international peer-reviewed Open Access quarterly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 600 CHF (Swiss Francs). English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.
