Genotype-phenotype associations in a nonmodel prokaryote

Measuring growth of tranpsoson mutants under a variety of nutrition and stress conditions helped define the biological functions of nonessential genes of Francisella novicida

Coordinated host responses during pyroptosis

Two conserved secretion pathways are shown to be initiated by caspase-1, lysosome exocytosis, and a parallel pathway resulting in cytokine release, and both enhance the antimicrobial nature of pyroptosis.

Evolution of Burkholderia pseudomallei

Whole genome comparisons of isolates from patients with recurring meliodosis infection identify deletions and deleterious mutations associated with increased antibiotic resistance

Highlights from Recent Publications
	Functional genetic screen of human diversity reveals that a methionine salvage enzyme regulates inflammatory cell death Proc Natl Acad Sci U S A. 2012 Jul 25 Dennis Ko It is shown that common human variation affecting expression of a single gene can alter susceptibility to two distinct cell death programs, and the same allele that promotes cell death is associated with improved survival of individuals with systemic inflammatory response syndrome. Commentary: Balancing resistance and infection tolerance through metabolic means
	Genotype-phenotype associations in a nonmodel prokaryote MBio. 2012 Mar 20 M Enstrom To help define the biological functions of nonessential genes of Francisella novicida, the growth of arrayed members of a comprehensive transposon mutant library were measured under a variety of nutrition and stress conditions. The greatest surprise of the analysis was the large number of genotype-phenotype relationships that were not predictable from studies of Escherichia coli and other model species.
	A Widespread Bacterial Type VI Secretion Effector Superfamily Identified Using a Heuristic Approach Cell Host Microbe. 2012 May 17 A Russell A type VI secretion system (T6SS) of Pseudomonas aeruginosa was shown to deliver cell wall-targeting effectors to neighboring cells. Using parameters derived from experimentally validated bacterial T6SS effectors a phylogenetically disperse superfamily of T6SS-associated peptidoglycan-degrading effectors was identified.
