Importance of organism and transcriptomes | The Heterosigma akashiwo strain CCMP 452 was initially isolated in Conover Maine (1952). This ~10 um alga rapidly divides as a vegetative cell and can form overwintering cysts that initiate massive, destructive blooms that impact eco-cohort survival at every trophic level. H. akashiwo is found in temperate and sub-tropical waters world-wide and often serves as the primary producer in coastal ecosystems. Intense studies of H. akashiwo for at least 40 years have generated a huge literature concerning the physiology, biochemistry and molecular biology of this organism. |
