Table 6 Genes regulated in the domoic acid (DA) induced grazer treatments that are involved or suggested to be involved in the biosynthesis of DA

From: Transcriptomic responses to grazing reveal the metabolic pathway leading to the biosynthesis of domoic acid and highlight different defense strategies in diatoms
