Here, we examine resistance and infection costs of a generalist fungal pathogen (Metschnikowia bicuspidata) capable of infecting a number of host species. Costs were quantified as reductions in host lifespan, total reproduction, and mean clutch size as a function of pathogen exposure (resistance cost) or infection (infection cost).
species of fungal pathogen, Ophiostoma ulmi and O. novo-ulmi, respectively. Their geographic origins remain unknown, despite a number of expeditionary searches, but both species are believed to have come from Asia (Brasier 1990; Brasier and Mehrotra 1995). O. ulmi and O. novo-ulmi differ markedly in many important behavioural and genetical ...

We tested the effects of tree diversity and the proportion of neighbouring host and non-host species with respect to the foliar fungal pathogens of Tilia cordata and Quercus petraea in the Kreinitz tree diversity experiment in Germany. We hypothesized that fungal pathogen richness increases while infestation decreases with increasing local tree diversity.
Candida species cause infections in individuals with deficient immune systems. Th1-type cell-mediated immunity (CMI) is required for clearance of a fungal infection. Candida albicans is a kind of diploid yeast that commonly occurs among the human gut microflora. C. albicans is an opportunistic pathogen in humans. Abnormal over-growth of this fungus can occur, particularly in immunocompromised ...
The cucurbit vegetables, including cucumbers, melons and pumpkins, have been cultivated for thousands of years without fungicides. However, their seed germination stage is prone to be infected by soil-borne fungal and oomycete pathogens. Endophytes are symbionts that reside inside plant tissues including seeds. Seed endophytes are founders of the juvenile plant microbiome and can promote host ...
Investigating Host Induced Meiosis in a Fungal Plant Pathoge n 413 An overview of how meiosis proceeds in U. maydis was presented by Donaldson and Saville (2008). Since the early stages of meiosis occur in planta and meiosis is temporally linked to the formation of thick walled dormant teliospores, direct microscopic
