17. Specificity in natural and artificial cyanobacterial symbioses
Abstract : Cyanobacteria, primarily of the genus Nostoc, form symbioses with a wide variety of plants. The diversity of cyanobacterial strains in these symbioses, and the specificity of interaction, vary greatly. A high diversity at the strain level has been suggested for bryophytes and cycads, whereas a low diversity is found in lichens. READ MORE

18. The tRNALeu (UAA) Intron of Cyanobacteria : Towards Understanding a Genetic Marker
Abstract : The tRNALeu (UAA) intron has been recorded in the plastid genome of many algae and land plants and was the first intron to be discovered in cyanobacteria. In all known cases it interrupts the tRNALeu anticodon loop at a conserved position (U-intron-AA). READ MORE

19. The novel sources of the neurotoxin BMAA in aquatic environments
Abstract : Neurotoxinet β -N-metylamino -L-alanin (BMAA) anses vara en potentiell miljöriskfaktor för utvecklingen av den neurodegenerativa sjukdomen amyotrofisk lateralskleros (ALS) och har en potentiell roll i flertalet andra neurodegenerativa sjukdomar. Sedan 2003, då det upptäcktes att BMAA produceras av den symbiotiska cyanobakterien Nostoc punctiforme har flera andra BMAA producerande cyanobakteriearter identifierats. READ MORE

20. Expression and synthetic activation of [FeFe]-hydrogenases in cyanobacteria
Abstract : Photosynthetic microbes can be utilized for hydrogen production, generating a clean, carbon neutral energy carrier from abundant substrates. Cyanobacteria are photosynthetic prokaryotes with large potential for biotechnological energy applications and several strains are capable of hydrogen production. READ MORE
