MetabolomicsNatural polymorphism of ZmICE1 contributes to amino acid metabolism that impacts cold tolerance in maize

Cold stress negatively affects maize (Zea mays L.) growth, development and yield. Metabolic adjustments contribute to the adaptation of maize under cold stress. We show here that the transcription factor INDUCER OF CBF EXPRESSION 1 (ZmICE1) plays a prominent role in reprogramming amino a...

TranscriptomicsGene expression response to copper toxicity between coastal and open ocean strains of marine Synechococcus
Marine cyanobacteria are thought to be the most sensitive of the phytoplankton groups to copper toxicity, yet little is known of the transcriptional response of marine Synechococcus to copper shock. Global transcriptional response to two levels of copper shock was assayed in both a coastal and an o...

TranscriptomicsInsufficiency of Copper Ion Homeostasis Causes Freeze-Thaw Injury of Yeast Cells
Saccharomyces cerevisiae is exposed to freeze-thaw stress in commercial processes including frozen dough baking. The cell viability and fermentation activity after freeze-thaw were dramatically decreased due to freeze-thaw injury. Because freeze-thaw injury involves complex phenomena, the mechanis...

TranscriptomicsRNA-seq of Arabidopsis spl7 identifies two genes required for copper acquisition and a copper dependence of iron homeostasis
The transition metal copper (Cu) is an essential element for all living organisms. In plants, Cu plays key roles in electron transport chains of chloroplasts and mitochondria, as well as in cell wall metabolism, ethylene perception, molybdenum cofactor synthesis and oxidative stress protection. Beca...

TranscriptomicsZinc deficiency impacts CO2 assimilation and disrupts copper homeostasis in Chlamydomonas reinhardtii
Zinc is an essential nutrient because of its role in catalysis and in stabilizing protein structure, but excess zinc can also be deleterious. Four nutritional zinc states have been identified in the alga Chlamydomonas reinhardtii: zinc toxic, zinc replete, zinc deficient and zinc limited. Growth is ...

TranscriptomicsSystems analysis of Chlamydomonas Cu nutrition reveals connections between Cu and multiple O2-dependent metabolic steps
We used digital gene expression (NlaIII sequence tags) and RNA-Seq to compare the transcriptomes of Cu-replete vs. Cu–deficient Chlamydomonas wild-type cells to reveal dozens of mRNAs whose abundance is modified. Half of the corresponding genes are targets of CRR1, a master regulator of nutritional ...

no omics definedTranscription profiling of copper-stressed Pseudomonas aeruginosa
Anthropogenic pollution has increased the levels of heavy metals in the environment. Bacterial populations continue to thrive in highly polluted environments and bacteria must have mechanisms to counter heavy metal stress. We chose to examine the response of the environmentally-relevant organism P...

ProteomicsCopper detoxification machinery of the brain-eating amoeba Naegleria fowleri involves copper-translocating ATPase and the antioxidant system
Copper is a trace metal that is necessary for all organisms but toxic when present in excess. Different mechanisms to avoid copper toxicity have been reported to date in pathogenic organisms such as Cryptococcus neoformans and Candida albicans. However, little if anything is known about pathogenic p...

ProteomicsThe effect of elevated copper concentrations on protein production in copper and sulfite tolerant S. cerevisiae
Copper tolerance and sulfite tolerance are two well-studied phenotypic traits of Saccharomyces cerevisiae. The genetic bases of these traits are derived from allelic expansion at the CUP1 locus and reciprocal translocation at the SSU1 locus, respectively. Previous work identified a negative associat...
