| Abstract |
Synechococcus sp. WH 8102 is a motile marine cyanobacterium isolated originally from the Sargasso Sea. To test the response of this organism to cadmium (Cd), generally considered a toxin, cultures were grown in a matrix of high and low zinc (Zn) and phosphate (PO4 (3-)) and were then exposed to an addition of 4.4 pM free Cd(2+) at mid-log phase and harvested after 24 h. Whereas Zn and PO4 (3-) had little effect on overall growth rates, in the final 24 h of the experiment three growth effects were noticed: (i) low PO4 (3-) treatments showed increased growth rates relative to high PO4 (3-) treatments, (ii) the Zn/high PO4 (3-) treatment appeared to enter stationary phase, and (iii) Cd increased growth rates further in both the low PO4 (3-) and Zn treatments. Global proteomic analysis revealed that: (i) Zn appeared to be critical to the PO4 (3-) response in this organism, (ii) bacterial metallothionein (SmtA) appears correlated with PO4 (3-) stress-associated proteins, (iii) Cd has the greatest influence on the proteome at low PO4 (3-) and Zn, (iv) Zn buffered the effects of Cd, and (v) in the presence of both replete PO4 (3-) and added Cd the proteome showed little response to the presence of Zn. Similar trends in alkaline phosphate (ALP) and SmtA suggest the possibility of a Zn supply system to provide Zn to ALP that involves SmtA. In addition, proteome results were consistent with a previous transcriptome study of PO4 (3-) stress (with replete Zn) in this organism, including the greater relative abundance of ALP (PhoA), ABC phosphate binding protein (PstS) and other proteins. Yet with no Zn in this proteome experiment the PO4 (3-) response was quite different including the greater relative abundance of five hypothetical proteins with no increase in PhoA or PstS, suggesting that Zn nutritional levels are connected to the PO4 (3-) response in this cyanobacterium. Alternate ALP PhoX (Ca) was found to be a low abundance protein, suggesting that PhoA (Zn, Mg) may be more environmentally relevant than PhoX. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 17 December 2013.
All research outputs
#20,213,623
of 22,736,112 outputs
Outputs from Frontiers in Microbiology
#22,186
of 24,598 outputs
Outputs of similar age
#248,822
of 280,808 outputs
Outputs of similar age from Frontiers in Microbiology
#264
of 407 outputs
Altmetric has tracked 22,736,112 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 24,598 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.3. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 280,808 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 407 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
