Gene Symbol

  • Os03g0133400 <=> CEBiP


Function

  • The plasma membrane glycoprotein CEBiP, which possesses LysM domains, is a receptor for the chitin elicitor (CE) in rice.
  • Perception of CE by CEBiP contributes to disease resistance against the rice blast fungus, Magnaporthe oryzae, and that enhanced responses to CE by engineering CEBiP increase disease tolerance.


Expression

  • The expression of either CRXa1 or CRXa3, each of which contains the whole extracellular portion of CEBiP, the whole intracellular domain of XA21, and the transmembrane domain from either CEBiP or XA21, induced cell death accompanied by an increased production of reactive oxygen and nitrogen species after treatment with CE.


Evolution

  • Knockdown of CEBiP expression allowed increased spread of the infection hyphae. To enhance defense responses to CE, the researchers constructed chimeric genes composed of CEBiP and Xa21, which mediate resistance to rice bacterial leaf blight.
