Iron and copper limitations differently affect growth rates and photosynthetic and physiological parameters of the marine diatom Pseudo-nitzschia delicatissima
Iron and copper limitations differently affect growth rates photosynthetic and physiological parameters marine diatom Pseudo-nitzschia delicatissima
2014/4/2
In ～ 50% of the ocean, iron (Fe) limits phytoplankton growth, including that of the diatom Pseudo-nitzschia. Fe-limited Pseudo-nitzschia spp. may produce the potent neurotoxin domoic acid (DA) to acce...
Iron, phosphorus, and nitrogen supply ratios define the biogeography of nitrogen fixation
Iron phosphorus nitrogen fixation
2014/4/2
We present a unified conceptual framework describing the competition between diazotrophs and non–
nitrogen-fixing marine plankton and their interaction with three essential nutrient elements: nitroge...
Increased intracellular concentrations of DMSP and DMSO in iron-limited oceanic phytoplankton Thalassiosira oceanica and Trichodesmium erythraeum
