Bacterial rhamnolipids are novel MAMPs conferring resistance to Botrytis cinerea in grapevine [PDF]

Plant, Cell & Environment, 2009
ABSTRACTRhamnolipids produced by the bacteria Pseudomonas aeruginosa are known as very efficient biosurfactant molecules. They are used for a wide range of industrial applications, especially in food, cosmetics and pharmaceutical formulations as well as in bioremediation of pollutants.

The plant pathogen Pseudomonas syringae pv. tomato is genetically monomorphic and under strong selection to evade tomato immunity.

PLoS Pathogens, 2011
Recently, genome sequencing of many isolates of genetically monomorphic bacterial human pathogens has given new insights into pathogen microevolution and phylogeography.

Quadrate orientation and joint reaction force underwent correlated evolution during suchian evolution

Journal of Anatomy, EarlyView.
The quadrate is the cranial bone of the nonmammalian jaw joint. The quadrate has long been hypothesized to mirror the direction of joint reaction forces (JRF) during feeding. This study uses 3D biomechanical modeling to reveal a striking evolutionary link between quadrate orientation and JRF direction, unlocking new insights into the dynamic forces ...

Analysis of Structures Containing Sharp Oblique Metal Edges in FDTD Using MAMPs [PDF]

IEEE Transactions on Antennas and Propagation, 2010
Previous enhancements to the finite difference time domain method have facilitated the analysis of structures such as those containing sharp metal edges which are aligned with the mesh or of smoothly curved metal objects. So far, however, there has been little work on the often encountered situation of thin metal edges which are inclined at an angle to

A Bacillus licheniformis Glycoside Hydrolase 43 Protein Is Recognized as a MAMP

International Journal of Molecular Sciences, 2022
Glycoside hydrolases from pathogens have often been reported as inducers of immune responses. However, the roles of glycoside hydrolase from plant-growth-promoting rhizobacteria (PGPR) in the resistance of plants against pathogens is not well studied.

Autoimmunity and Periodontitis

Journal of Periodontal Research, EarlyView.
In a microbe‐driven inflammatory environment, peptidyl‐arginine deiminase (PAD) enzymes from neutrophils and Porphyromonas gingivalis citrullinate both microbial and self‐antigens. B cell presentation of citrullinated or self‐mimicking epitopes activates T cells that assist B cells in antibody isotype switching, affinity maturation, epitope spreading ...

Quiescence of postharvest pathogens: a fungal inhibition process or an immune response of the unripe host fruit?

New Phytologist, EarlyView.
Summary Postharvest pathogens can infect fresh produce both before and after harvest, by direct or wound‐enhanced penetration, remaining quiescent until ripening. Biotrophic‐like postharvest pathogens persist beneath host cells and can remain in a state of quiescence.

Chitin and chitin-related compounds in plant–fungal interactions

Mycology, 2018
Chitin is the second abundant polysaccharide in the world after cellulose. It is a vital structural component of the fungal cell wall but not for plants.

XopR, a Type III Effector Secreted by Xanthomonas oryzae pv. oryzae, Suppresses Microbe-Associated Molecular Pattern-Triggered Immunity in Arabidopsis thaliana

Molecular Plant-Microbe Interactions, 2012
Xanthomonas oryzae pv. oryzae is the causal agent of bacterial blight of rice. The XopR protein, secreted into plant cells through the type III secretion apparatus, is widely conserved in xanthomonads and is predicted to play important roles in bacterial

Decoding plant defense signaling using the defenseless mutant

New Phytologist, EarlyView.
Summary Can plants live without defenses? Mutant analysis in Arabidopsis thaliana has identified numerous regulators of biotic, abiotic, and hormone‐based defenses, but the redundancy among separate defense pathways remains unexplored. We constructed an Arabidopsis mutant, defenseless, lacking six canonical defense pathways using abi1‐1 (abscisic acid),
