ProteomicsChronic iron limitation induces resistance to ROS
Diatoms are single celled photosynthetic bloom-forming algae that are responsible for at least 20% of global primary production. Nevertheless, more than 30% of the oceans are considered “ocean deserts” due to iron limitation. We used the diatom Phaeodactylum tricornutum as a model system to explore ...

TranscriptomicsTranscriptional Response to Iron Limitation in Pelagibacter ubique
We investigated the gene expression responses of Candidatus Pelagibacter ubique cultures to iron limitation. Differential expression was observed for genes in iron acquisition and incorporation operons. SfuC in particular was 16 times higher in iron-limited cultures and encodes a periplasmic iron-bi...

ProteomicsQuantitative proteomics of iron limitation in Klebsiella pneumoniae
Nutrient adaptation is key in limiting environments for the promotion of microbial growth and survival. In microbial systems, iron is an essential component for many cellular processes and bioavailability varies greatly among different conditions. In the bacterium, Klebsiella pneumoniae, the impact ...

ProteomicsThe synergy between plastid and mitochondria modulates responses to iron limitation in two Thalassosira diatom species
Iron (Fe) is an essential element for life. Therefore, oceanic phytoplankton must adapt to the naturally low iron levels in modern oceans. Diatoms are a highly diverse and successful phytoplankton taxon that accounts for around 20% of global primary production. Previous studies have shown that they ...

TranscriptomicsExpression data from roots of Arabidopsis grown under sulfur, iron or potassium limitation
Deprivation of mineral nutrients causes significant retardation of plant growth. This slow growth is assumed to be associated with both nutrient specific transcriptional responses and additionally with common transcription patterns. In this study we adjusted the external supply of iron, potassium an...

Proteomics,MultiomicsTranscriptional and translational regulatory responses to iron limitation in the globally distributed marine bacterium Candidatus Pelagibacter ubique
Investigation of the gene expression responses of Candidatus Pelagibacter ubique cultures to iron limitation in natural seawater media supplemented with a siderophore to chelate iron. Quantitative peptide mass spectrometry revealed that sfuC protein abundance increased 27-fold, despite an average de...

TranscriptomicsComparative analysis of the response to iron-limitation in the absence of oxygen in R. sphaeroides [Microarray]
High intracellular levels of unbound iron can contribute to the production of reactive oxygen species (ROS) in the Fenton reaction, while depletion of iron limits the availability of iron containing proteins, some of which have important functions in the oxidative stress defense. Vice versa increase...

ProteomicsProteomics analysis reveals differential acclimation of coastal and oceanic Synechococcus to climate warming and iron limitation
In many regions of the ocean, anthropogenic warming will coincide with iron (Fe) limitation. Interactive effects between warming and Fe limitation on phytoplankton physiology and biochemical function are likely, as temperature and Fe availability affect many of the same essential cellular pathways. ...
