It is common knowledge that pathogenic viruses can change hosts, with avian influenza, the
HIV, and the causal agent of variant Creutzfeldt–Jacob encephalitis as well-known …

Hamilton's inclusive fitness theory provides a leading explanation for the problem of
cooperation. A general result from inclusive fitness theory is that, except under restrictive …

The siderophore pyochelin is made by a thiotemplate mechanism from salicylate and two
molecules of cysteine. In Pseudomonas aeruginosa, the first cysteine residue is converted to …

A hydroxamate-based chemosensor, which responds fluorescently and colorimetrically to
FeIII in micromolar ranges, has been developed. The rhodamine hydroxamate probe is …

Aparajita Das et al. 2 rial or dead organisms. Fungi obtain nutrients to absorb by secreting
digestive enzymes onto the food source. The enzymes break down, or digest, the food. The …

Magnetotactic bacteria are a physiologically diverse group of prokaryotes whose main
common features are the biomineralization of magnetosomes and magnetotaxis, the passive …

In response to iron starvation, Pseudomonas aeruginosa produces the siderophore
pyochelin. When secreted to the extracellular environment, pyochelin chelates iron and …

Iron is an essential nutrient for almost all bacteria; however, at neutral pH its bioavailability is
limited. Siderophores are iron-binding compounds of low molecular weight that enable the …

ABSTRACT A genetically tractable model plant pathosystem, Pseudomonas syringae pv.
tomato DC3000 on tomato and Arabidopsis thaliana hosts, was used to investigate the role …

Significant production of superoxide, a known reductant of both inorganic and organically
complexed iron (III), occurs in natural systems by both biotic and abiotic pathways. We have …
