NO signal at the crossroads: polyamine-induced nitric oxide synthesis in plants?
Polyamines, such as spermine, spermidine and putrescine, are ubiquitous polycationic compounds that are produced by almost all living organisms, including plants, animals, fungi and bacteria. Polyamines are multifunctional and interact with polyanionic biomolecules such as DNA or protein. However, despite their potential significance, the polyamine-dependent signal transduction system has not been revealed yet. Ni Ni Tun and colleagues have recently reported a possible linkage between polyamine and nitric oxide (NO), another ubiquitous signalling molecule.
