Two modes of pathogen recognition by plants.
M ore than 50 years ago, J. B. S. Haldane (1) presciently predicted that polymorphism in proteins governing host–pathogen interactions was driven by the rapid rates of microbial evolution. He suggested that slowly evolving host species could only manage to dodge microbial infection by generating high levels of polymorphism in the relevant immune system genes. These ideas were in part inspired b...
متن کاملTwo Modes of Ligand Recognition by TLRs
Toll-like receptors (TLRs) are membrane-bound sensors that detect and respond to microbial infection. Two studies in Cell, one in this issue, reveal how TLRs recognize their ligands. Kim et al. (2007) recently reported the structure of TLR4 bound to the accessory protein MD-2 and its antagonist, the drug eritoran. In this issue, Jin et al. (2007) describe the crystal structure of a complex betw...
متن کاملFungal Peptide Elicitors: Signals Mediating Pathogen Recognition in Plants
Highly sensitive and specific recognition systems for microbial pathogens are essential for disease resistance in plants. Proteinaceous elicitors activating plant pathogen defense have been identified in numerous antagonistic plant/fungus interactions. Precisely defined signal structures required for elicitor-mediated activation of plant defense are indicative of the involvement of receptors in...
متن کاملRecognition of pathogens by plants
Plants must respond appropriately to a broad array of abiotic and biotic factors in the attempt to accumulate nutrient reserves and reach reproductive maturity. To complicate matters, their stockpile of nutrients makes them prime targets for pathogen attack. Phytopathogenic bacteria, fungi, and viruses all make raids on the stockpile, yet most plants are able to remain disease free. Plants have...
متن کاملModulation of Pathogen Recognition by Autophagy
Autophagy is an ancient biological process for maintaining cellular homeostasis by degradation of long-lived cytosolic proteins and organelles. Recent studies demonstrated that autophagy is availed by immune cells to regulate innate immunity. On the one hand, cells exert direct effector function by degrading intracellular pathogens; on the other hand, autophagy modulates pathogen recognition an...
