Trichodesmium, a keystone marine microbe, can fix a theoretically unlimited supply of carbon and nitrogen; therefore the next most-limiting nutrients Fe and P seem to limit its growth and activity. Which nutrient limits Trichodesmium in nature?
The project used metaproteomics, quantitative proteomics, mathematical modelling, and network analysis.
This work was published in 2020. The transcript abundances from some of the same transects reflect different patterns - an interesting comparison that can be found here (Cerdan-Garcia et al., 2021). I also recommend this nice study considering similar trade offs in nutrient acquisition by phytoplankton here (McCain et al., 2021.
