Foliar Pine Pathogens From Different Kingdoms Share Defence-Eliciting Effector Proteins.

ABSTRACT: Dothistroma needle blight, Cyclaneusma needle blight and red needle cast are devastating foliar pine diseases caused by the fungi Dothistroma septosporum and Cyclaneusma minus and the oomycete Phytophthora pluvialis, respectively. These pathogens colonise the host apoplast, secreting effector proteins to promote infection and disease. If these effectors are recognised by corresponding host resistance proteins, they activate the plant immune system to stop pathogen growth. We aimed to identify and characterise effectors that are common to all three pathogens. Using D. septosporum as a starting point, three candidate effectors (CEs) were investigated: Ds69335 (a CAP protein) and Ds131885, both of which have sequence and structural similarity to CEs of C. minus and P. pluvialis, and Ds74283,
