- •
Higher toxin was observed in A. minutum when grown in P-depleted, NO3-grown cultures or above-ambient NH4.
- •
sxtA1 might not be involved in the STX biosynthesis pathway of the tropical Pacific A. minutum.
- •
Expression of AmsxtI was induced only at P-depleted conditions.
- •
AmsxtI is likely involved in P-recycling metabolism and simultaneously enhances PST production.
