Cytokinins and auxins in plant-pathogen interactions – An overview

  • P.E. Jameson


Alterations in plant development are frequently observed following pathogen infection. Infection by virus frequently results in stunting of growth, and the chlorosis and abscission of leaves; infection by fungi is often notable for green island formation and growth malformations; and infection by some bacteria results in the formation of galls. While the area of plant-pathogen interactions is currently receiving considerable attention and some plant-pathogen interactions are well characterised with both cytokinins and auxins being implicated (infection by Agrobacterium tumefaciens being the obvious example), there has been relatively little published in the recent literature pertaining to the involvement of cytokinins and auxins in viral, fungal and other forms of bacterial pathogenesis. This overview focuses on what is known concerning the strategies utilised by gall-forming bacteria, and fungal and viral phytopathogens to manipulate the endogenous cytokinin and/or auxin content of their host plant.
