Insights from the genome of the biotrophic fungal plant pathogen Ustilago maydis
Ustilago maydis is a ubiquitous pathogen of maize and a well-established model organism for the study of plant–microbe interactions. This basidiomycete fungus does not use aggressive virulenceExpand

Isolation and characterization from pathogenic fungi of genes encoding ammonium permeases and their roles in dimorphism
Nutrient sensing plays important roles in fungal development in general, and specifically in critical aspects of pathogenicity and virulence, for both animal and plant pathogens. Dimorphic pathogensExpand

Differentiation of Giardia duodenalis from other Giardia spp. by using polymerase chain reaction and gene probes.
Giardia spp. are waterborne organisms that are the most commonly identified pathogenic intestinal protozoans in the United States. Current detection techniques for Giardia species in water includeExpand

Group-beneficial traits, frequency-dependent selection and genotypic diversity: an antibiotic resistance paradigm
The evolution of group-beneficial traits potentially allows the survival of 'cheaters' that would otherwise be unfit. Here we describe experimental work on group-beneficial traits and theExpand

Genetics of morphogenesis and pathogenic development of Ustilago maydis.
Ustilago maydis has emerged as an important model system for the study of fungi. Like many fungi, U. maydis undergoes remarkable morphological transitions throughout its life cycle. Fusion ofExpand

Protection of Salmonella by ampicillin-resistant Escherichia coli in the presence of otherwise lethal drug concentrations
Microbial systems have become the preferred testing grounds for experimental work on the evolution of traits that benefit other group members. This work, based on conceptual and theoretical models ofExpand

Chaos of Rearrangements in the Mating-Type Chromosomes of the Anther-Smut Fungus Microbotryum lychnidis-dioicae
Sex chromosomes in plants and animals and fungal mating-type chromosomes often show exceptional genome features, with extensive suppression of homologous recombination and cytological differentiationExpand

The evolution of group-beneficial traits in the absence of between-group selection.
One specific prediction emerging from trait-group models of natural selection is that when individuals possess traits that benefit other group members, natural selection will favor "cheating" (i.e.Expand

Isolates of Microbotryum violaceum from North American host species are phylogenetically distinct from their European host-derived counterparts.
Microbotryum violaceum is a basidiomycete that infects the anthers of its Caryophyllaceae host species. Individual fungal isolates are host limited, though they are not morphologically distinct. ThisExpand

Evolution of altruists and cheaters in near-isogenic populations of Escherichia coli.
Emergence of antibiotic-resistant bacteria threatens the continued efficacy of many critical drugs used to treat serious infections. What if such resistant organisms could also act as altruists andExpand
