Plant innate immunity: perception of conserved microbial signatures

Annu Rev Plant Biol. 2012;63:451-82. doi: 10.1146/annurev-arplant-042811-105518. Epub 2012 Feb 9.

Abstract

Plants and animals sense conserved microbial signatures through receptors localized to the plasma membrane and cytoplasm. These receptors typically carry or associate with non-arginine-aspartate (non-RD) kinases that initiate complex signaling networks cumulating in robust defense responses. In plants, coregulatory receptor kinases have been identified that not only are critical for the innate immune response but also serve an essential function in other regulatory signaling pathways.
