Transcriptomic responses of Heterosigma akashiwo to nitrogen deficiency and urea
This study elucidates the molecular adaptation mechanisms of the harmful algal bloom species Heterosigma akashiwo under nitrogen deficiency and when using urea as a nitrogen source. These findings highlight its ability to utilize urea as the sole nitrogen source and to survive nitrogen deficiency, traits that may facilitate the proliferation of H. akashiwo blooms in nitrogen deficiency marine environments.
