Journal ArticleDOI
Type III Secretion Machines: Bacterial Devices for Protein Delivery into Host Cells
Jorge E. Galán,Alan Collmer +1 more
TL;DR: Several Gram-negative pathogenic bacteria have evolved a complex protein secretion system termed type III to deliver bacterial effector proteins into host cells that then modulate host cellular functions.
Journal ArticleDOI
The complete genome sequence of the Arabidopsis and tomato pathogen Pseudomonas syringae pv. tomato DC3000

Lazarowitz,Gregory B. Martin,David J. Schneider,Xiaoyan Tang,Carol L. Bender,Owen White,Claire M. Fraser,Alan Collmer +43 more
TL;DR: The complete genome sequence of the model bacterial pathogen Pseudomonas syringae pathovar tomato DC3000 (DC3000), which is pathogenic on tomato and Arabidopsis thaliana, is reported and 1,159 genes unique to DC3000 are revealed, of which 811 lack a known function.
Journal ArticleDOI
Harpin, elicitor of the hypersensitive response produced by the plant pathogen Erwinia amylovora
Zhong-Min Wei,Ron Laby,Cathy H. Zumoff,David W. Bauer,Sheng Yang He,Alan Collmer,Steven V. Beer +6 more
TL;DR: A proteinaceous elicitor of the plant defense reaction known as the hypersensitive response was isolated from Erwinia amylovora, the bacterium that causes fire blight of pear, apple, and other rosaceous plants.
Journal ArticleDOI
TYPE III SECRETION SYSTEM EFFECTOR PROTEINS: Double Agents in Bacterial Disease and Plant Defense
James R. Alfano,Alan Collmer +1 more
TL;DR: Investigations of the functions of effectors within plant cells have demonstrated the plasma membrane and nucleus as subcellular sites for several effectors, revealed some effectors to possess cysteine protease or protein tyrosine phosphatase activity, and provided new clues to the coevolution of bacterium-plant interactions.
Journal ArticleDOI
The type III (Hrp) secretion pathway of plant pathogenic bacteria: trafficking harpins, Avr proteins, and death.
James R. Alfano,Alan Collmer +1 more
TL;DR: The ability of plant pathogenic bacteria to deliver deathtriggering proteins to the interior of plant cells was revealed in a rapid succession of papers in 1996 that transformed the concepts of bacterial plant pathogenicity and is being studied as an entry to the larger problem of pathogenesis.
