| Outline of Final Research Achievements |
To clarify the mechanisms of salt tolerance in cyanobacteria and marine microalgae, we analyzed them at molecular level. As a result, novel findings below were observed. (1) Candidate enzyme for DMSP synthetic pathway in marine microalgae was obtained. (2) Nitrate oversupply affected glycine betaine and mycosporine-2-glycine synthesis in response to changes of salinity in a halotolerant cyanobacterium. (3) DNA damage protecting and free radical scavenging properties of mycosporine-2-glycine were observed. (4) Overexpression of halophilic serine hydroxymethyltransferase in fresh water cyanobacterium results in enhanced salinity tolerance. etc.
