Same tune, different song-cytokinins as virulence factors in plant-pathogen interactions?

Abstract:

:Virulence factors are molecules that enable plant pathogens to infect and colonize host tissues successfully. These molecules co-evolve with host genes to ensure functionality and to avoid recognition by the host immune system. Some pathogens also produce the plant growth hormone cytokinin (CK) and other plant hormones that contribute to virulence without being subjected to the molecular arms race. Here, we summarize recent findings regarding the role of CKs during infection and the establishment of plant diseases. We discuss commonalities and differences in CK biosynthesis, perception, and activity in infections by different phytopathogenic bacteria, fungi, nematodes and parasitic plants. Finally, we attempt to answer the question if CKs can be classified as bona fide virulence factors.

  • The perception of gibberellins: clues from receptor structure.

    abstract::The discovery of GID1, a soluble receptor for gibberellins (GAs), has revealed new insights into how GA is perceived. X-ray analysis has demonstrated similarities in the tertiary structure of GID1 to hormone sensitive lipase (HSL), and the GA-binding pocket of GID1 corresponds to the active site of HSL. X-ray analysis...
