Signaling mechanisms in pattern-triggered immunity (PTI)

Mol Plant. 2015 Apr;8(4):521-39. doi: 10.1016/j.molp.2014.12.022. Epub 2015 Jan 9.


In nature, plants constantly have to face pathogen attacks. However, plant disease rarely occurs due to efficient immune systems possessed by the host plants. Pathogens are perceived by two different recognition systems that initiate the so-called pattern-triggered immunity (PTI) and effector-triggered immunity (ETI), both of which are accompanied by a set of induced defenses that usually repel pathogen attacks. Here we discuss the complex network of signaling pathways occurring during PTI, focusing on the involvement of mitogen-activated protein kinases.

Keywords: MAPKs; PTI; plant defenses; plant immunity; signaling mechanisms.
