Effector identification in the pine pathogen Dothistroma septosporum

L. Hunziker, C.H. Mesarich, R.L. McDougal and R.E. Bradshaw


Effectors are molecules produced by plant-associated organisms, such as fungal pathogens, that facilitate infection of specific plant hosts. Some effectors directly or indirectly suppress host defence responses while others help to mask the foreign invader from recognition by the plant. Plants can also recognise and respond to specific effectors to mount a resistance response. Thus the study of effectors is important for an understanding of plant-pathogen interactions. Dothistroma septosporum causes Dothistroma needle blight (DNB), a conifer disease of worldwide importance. In this study, effector genes specific to the D. septosporum-Pinus radiata interaction were identified. A bioinformatics pipeline was employed to predict effector candidates on the basis of characteristics such as secretion from the fungus and expression in planta. Using this pipeline, 55 effector candidates for future analysis were identified.

Keywords: bioinformatics pipeline, forest pathogen, Pinus radiata, secreted proteins, in planta expression.
