NOTEWORTHY PLANT DISEASE NOTES. New Cross-Domain Bacterial Pathogen. Enterobacter sakazakii is a human pathogen that causes infections of the bloodstream and central nervous system in infants. It has been found as a contaminant in powdered infant formula. In the March issue of Plant Disease, R. Keith and co-workers report the first plant disease caused by E. sakazakii, an atypical internal yellowing of papaya fruit. Read the Note.

Plant Disease Editor's Pick by Dr. Anthony Keinath, Editor-in-Chief 

 

Not again?!? When native redbay (Persea borbonia) began dying in the southeastern USA, scientists, foresters, and the public were puzzled. Fraedrich, Harrington, and co-authors have identified the culprits and completed Koch's postulates for a Raffaelea sp. Read A Fungal Symbiont of the Redbay Ambrosia Beetle Causes a Lethal Wilt in Redbay and Other Lauraceae in the Southeastern United States, to see how the epidemiology of laurel wilt parallels Dutch elm disease.

MPMI

Editor's Pick by Dr.

Jonathan Walton, Editor-in-Chief

 

In the February issue of MPMI, Rico and Preston show that Pseudomonas syringae DC3000 is quite well adapted metabolically to the nutrients found in the apoplast of its host, tomato. Some other species and strains of Pseudomonas that grow on different hosts have quite different nutrient assimilation profiles.

Phytopathology

Editor's Pick by Dr. Robert Gilbertson, Editor-in-Chief 
 

New insight into the mechanism by which the vascular pathogen, Eutypa lata, infects and causes disease is revealed by examining the grapevine wood polymers degraded and enzymes and secondary metabolites produced by the fungus. The results revealed a possible mechanism of disease tolerance in grapevine, and raised important new questions about fungal colonization of woody hosts.Read more: Pathogenesis of Eutypa lata in Grapevine: Identification of Virulence Factors and Biochemical Characterization of Cordon Dieback.
