DESCRIPTION:One of the most spectacular phenomena in biology is the comple
 te hijacking of hosts by pathogens such that hosts become ‘zombies’ de
 stined to maximize pathogen survival. Phytoplasmas induce dramatic changes
  in plant development\, including proliferation of stems (witches’ broom
 s) and the reversion of flowers into leafy structures. These bacterial pat
 hogens produce small virulence proteins (effectors) that promote the degra
 dation of TCP and MADS-box transcription factors in plants resulting in al
 tered leaf development\, reduced jasmonate (JA) synthesis and the conversi
 on of flowers into leaves. Both effectors promote bacterial growth and ins
 ect vector colonization. This is important\, because phytoplasmas depend o
 n insect vectors for transmission to a diverse range of plant species. Thu
 s\, bacterial effectors can reach beyond the host-pathogen interface to af
 fect a third organism in a biological interaction. \n
