"Despite decades of research, the trigger that causes algal blooms to begin poisoning their environment has long confounded scientists.
Now, researchers from Scripps and UC San Diego have found the genetic underpinning of domoic acid, a harmful neurotoxin. In a new study published in Science, researchers describe three genes responsible for producing domoic acid in the phytoplankton Pseudo-nitzschia.
Monitoring how the cluster of genes behave could one day yield information on which environmental or biological triggers are responsible for activating them, according to Bradley Moore, a professor of marine chemical biology and geneticist at Scripps and UC San Diego. That information could help fisheries and public health officials predict when harmful algal blooms will occur, allowing them to effectively prepare."
