Editing Chitin (section)

===Plants===
Plants also have receptors that can cause a response to chitin, namely chitin elicitor receptor kinase 1 and chitin elicitor-binding protein.<ref name=Komi2017rev/>  The first chitin receptor was cloned in 2006.<ref name=Sanchez2015rev>{{cite journal|last1=Sánchez-Vallet|first1=A|last2=Mesters|first2=JR|last3=Thomma|first3=BP|title=The battle for chitin recognition in plant-microbe interactions.|journal=FEMS Microbiology Reviews|date=March 2015|volume=39|issue=2|pages=171–83|doi=10.1093/femsre/fuu003|pmid=25725011|issn=0168-6445|doi-access=free|hdl=20.500.11850/97275|hdl-access=free}}</ref>  When the receptors are activated by chitin, genes related to plant defense are expressed, and [[jasmonate]] hormones are activated, which in turn activate systemic defenses.<ref name=Sharp2013rev/>  [[Commensalism|Commensal]] fungi have ways to interact with the host immune response that, {{as of|2016|lc=y}}, were not well understood.<ref name=Sanchez2015rev/>

Some pathogens produce chitin-binding proteins that mask the chitin they shed from these receptors.<ref name=Sharp2013rev>{{cite journal|last1=Sharp|first1=Russell G.|title=A Review of the Applications of Chitin and Its Derivatives in Agriculture to Modify Plant-Microbial Interactions and Improve Crop Yields|journal=Agronomy|date=21 November 2013|volume=3|issue=4|pages=757–793|doi=10.3390/agronomy3040757|language=en|doi-access=free}}</ref><ref>{{cite journal|last1=Rovenich|first1=H|last2=Zuccaro|first2=A|last3=Thomma|first3=BP|title=Convergent evolution of filamentous microbes towards evasion of glycan-triggered immunity.|journal=The New Phytologist|date=December 2016|volume=212|issue=4|pages=896–901|doi=10.1111/nph.14064|pmid=27329426|doi-access=free}}</ref> ''[[Zymoseptoria tritici]]'' is an example of a fungal pathogen that has such blocking proteins; it is a major pest in [[wheat]] crops.<ref name=Kettles2016rev/>
