Abstract:

The presented study focuses on the biosynthesis and distribution of lipopeptides in the context of evolutionary history and life strategies of cyanobacteria. Cyanobacteria are ancient organisms often naturally exposed to situations in which other bacteria, such as Bacillus or Pseudomonas, were shown to employ lipopeptides to facilitate colony expansion or iron acquisition. The study explores these analogies and maps the distribution and diversity of lipopeptides across cyanobacteria with various lifestyles. Furthermore, the study provides evidence that widespread cyanobacterial lipopeptides containing a particular structural motif with two -hydroxy aspartate residues are a part of iron stress response and likely facilitate iron acquisition. The gathered information aims to integrate and deepen our knowledge of the ecophysiological roles of cyanobacterial lipopeptides.
