Brassicales have more recently diverged from the other core eudicot lineages, the rosids, than from asterids, which have a fully elaborated MAMP system. Although the receptors share many structural and biochemical similarities with animal receptors, they may have a different downstream signaling network due to their evolutionary history.
Within the order Brassicales, SGI and RGI play a role in plant defense. thaliana undergo rapid evolution, and suggest that this may have played a role in the ability of this plant to develop resistance to Pseudomonas strains. Eleven genotypes from two populations were able to induce only barely detectable levels of the elf18- or flagellin-triggered immune response, whereas one genotype from population FL-6 was consistently unable to mount a defense response to elf18 and flagellin. We found significant differences in the magnitude of the immune response to different MAMP variants among the tested Pseudomonas strains. thaliana, suggesting that MAMP receptors are under selection. Our phylogenetic analyses of MAMP receptor sequences revealed genetic differentiation and short-term evolution in A. We determined the response to different MAMP variants using the synthetic peptide elf18 or flagellin in two species of Pseudomonas bacteria which were previously isolated from A. thaliana and tested if it affects their ability to mount a defense response to MAMP-triggered immunity (MTI). Here, we assessed differentiation of the MAMP response among natural populations of the model plant species A. It remains unclear, however, if the ability of plant organisms to mount an adequate immune response to their microbial threat is affected by evolutionary changes in their MAMP receptors. The MAMP-evoked defense response of the host plant is coordinated by receptors that detect MAMPs, which are evolutionarily conserved structural components of microorganisms, and in turn perceive them.
