How do diatoms cope with nitrogen and phosphorus colimitation? — Happy to share our new paper:

"Nitrogen status exerts dynamic control over phosphorus sensing and acquisition via PSR1 in colimited marine diatoms"

Nitrogen status exerts dynamic control over phosphorus sensing and acquisition via PSR1 in colimited marine diatoms

Diatoms exert reciprocal, fine-scale control of P acquisition by N availability, depending on the immediate needs of the cell.
