HABs are caused by microscopic algae that produce toxins. These toxins can accumulate in the food chain, and when humans or animals eat contaminated seafood, they can become sick. HABs can also cause skin irritation and respiratory problems.
The Bigelow Laboratory team studied a species of algae called Alexandrium catenella, which is responsible for one of the most common types of HABs in the Gulf of Maine. They found that the genes responsible for producing toxins are located on a specific chromosome in the algae's genome.
This discovery is important because it provides a target for developing new drugs and treatments to prevent HABs from becoming toxic. By blocking the expression of the genes responsible for producing toxins, scientists may be able to prevent HABs from causing harm.
"This is a major breakthrough in our understanding of how HABs become toxic," said Dr. Chris Bowler, director of the Bigelow Laboratory. "This discovery could lead to new ways to predict and prevent HABs, which would have a significant impact on public health and the marine environment."
HABs are a growing problem worldwide, and they are becoming more frequent and severe due to climate change. The Bigelow Laboratory team's discovery is a promising step forward in the fight against HABs.
