The Synthetic Elicitor DPMP (2,4-dichloro-6-{(E)-[(3-methoxyphenyl)imino]methyl}phenol) Triggers Strong Immunity in Arabidopsis thaliana and Tomato

چکیده
Synthetic elicitors are drug-like compounds that are structurally distinct from natural defense elicitors. They can protect plants from diseases by activating host immune responses and can serve as tools for the dissection of the plant immune system as well as leads for the development of environmentally-safe pesticide alternatives. By high-throughput screening, we previously identified 114 synthetic elicitors that activate expression of the pathogen-responsive CaBP22(-333)::GUS reporter gene in Arabidopsis thaliana (Arabidopsis), 33 of which are [(phenylimino)methyl]phenol (PMP) derivatives or PMP-related compounds. Here we report on the characterization of one of these compounds, 2,4-dichloro-6-{(E)-[(3-methoxyphenyl)imino]methyl}phenol (DPMP). DPMP strongly triggers disease resistance of Arabidopsis against bacterial and oomycete pathogens. By mRNA-seq analysis we found transcriptional profiles triggered by DPMP to resemble typical defense-related responses.

The title Schiff base compound, C(10)H(10)Cl(3)NO, was prepared by the condensation of 1-(3,5-dichloro-2-hy-droxy-phen-yl)ethanone with chloro-ethyl-amine. The imine adopts an E configuration with respect to the C=N bond. The H atom of the phenolic OH group is disordered over two positions with site occupation factors of 0.52 (7) and 0.48 (7), respectively, and the major occupancy component is ...
متن کاملThe Arabidopsis receptor kinase FLS2 binds flg22 and determines the specificity of flagellin perception.
Flagellin, the main building block of the bacterial flagellum, acts as a pathogen-associated molecular pattern triggering the innate immune response in animals and plants. In Arabidopsis thaliana, the Leu-rich repeat transmembrane receptor kinase FLAGELLIN SENSITIVE2 (FLS2) is essential for flagellin perception. Here, we demonstrate the specific interaction of the elicitor-active epitope flg22 ...

The asymmetric unit of the title compound, [Co(C(9)H(8)Cl(2)NO)(3)], contains three independent mol-ecules. In each mol-ecule, the Co(III) ion is coordinated by an O atom and an N atom from three bidentate 2,4-dichloro-6-(ethyl-imino-meth-yl)phenolate ligands in a slightly distorted octa-hedral environment. In the crystal, a weak C-H⋯Cl hydrogen bond is observed.
