Most of the phylogenetic diversity of life is found in bacteria and archaea, and is reflected in
the diverse metabolism and functions of bacterial and archaeal polyamines. The polyamine …

Plant growth-promoting rhizobacteria (PGPR) are members of the plant rhizomicrobiome
that enhance plant growth and stress resistance by increasing nutrient availability to the …

Ralstonia solanacearum thrives in plant xylem vessels and causes bacterial wilt disease
despite the low nutrient content of xylem sap. We found that R. solanacearum manipulates …

Summary The polyamine putrescine (1, 4‐diaminobutane) contributes to cellular fitness in
most organisms, where it is derived from the amino acids ornithine or arginine. In the …

Despite the abundance of iron in nature, iron acquisition is a challenge for life in general
because the element mostly exists in the extremely insoluble ferric (Fe3+) form in oxic …

Amino groups derived from naturally abundant amino acids or (di) amines can be used as
“shuttles” in nature for oxygen transfer to provide intermediates or products comprising NO …

Ubiquitous polyamine spermidine is not required for normal planktonic growth of Bacillus
subtilis but is essential for robust biofilm formation. However, the structural features of …

Polyamines such as spermidine and spermine are primordial polycations that are
ubiquitously present in the three domains of life. We have found that Gram‐positive bacteria …

Siderophores produced via nonribosomal peptide synthetase (NRPS) pathways serve as
critical virulence factors for many pathogenic bacteria. Improved knowledge of siderophore …

The siderophore synthetic system in Shewanella species is able to synthesize dozens of
macrocyclic siderophores in vitro with synthetic precursors. In vivo, however, although three …
