Abstract
Many plantassociated microbes are pathogens that impair plant growth and reproduction. Plants have evolved a series of complicated defense mechanism against pathogens during their long term process of coevolution. Plants innate immune system efficiently detects and wards off potentially dangerous microbes. A first layer of this system is based on sensitive perception of pathogenor microbeassociated molecular patterns (PAMPs) through pattern recognition receptors (PRRs) at the plants cell surface,which would active mitogenactivated protein kinase(MAPK) signaling cascade and burst early responses in plant resistance to pathogen attacks. The first layer recognizes and responds to many classes of microbes, including nonpathogens. With pathogens produce effectors to inhibit PTI, plants can perceive such effectors through additional receptors, typically nucleotide binding leucinerich repeat (NBLRR) proteins, to mount a second layer of defense called effect or triggered immunity (ETI). Here, we highlight recent literature on plants innate immune system, and based on a detailed understanding of plant immune function, we should focus on the combination of the use of PTI and ETI to expand the antimicrobial spectrum of plant effectively and improve plantss diseaseresistance.
