Cornichon Proteins: Unexpected Roles in Plant Pathogen Infection, ER Morphology Maintenance and Pollen Development
… of viral replication proteins and thus, viral infection, by manipulating the required host proteins. Brome mosaic virus (BMV) is a model of positive-strand RNA viruses and its replication can be recapitulated in yeast. Importantly, BMV replication protein 1a is the only required viral protein …

Systems View Of The Soybean Genetic Mechanisms Involved In The Response To Plant Pathogen Infection
… geneticists working towards improving traits for pathogen resistance.Results reported here provide a systemic view at both the genetic and biochemical level, and were generated by data-mining gene expression data from soybean cultivars inoculated with plant pathogens and also recombinant inbred …

Characterization of the Pathway Leading to the Synthesis of Salicylic Acid in Plants Resisting Pathogen Infection.
… is a plant hormone that accumulates with plant-pathogen interaction. This accumulation corresponds to the plant being resistant to infection and without it the plant is susceptible. In this study, primers of genes involved in the normal synthesis of SA were used in RT-PCR to compare gene …

Tetrodotoxin, fungal pathogen infection, and bacterial microbiome associations are variable in the skin microecosystems of two Taricha Newt species
… and species extinctions, caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd). While chytridiomycosis can result in host death, some amphibians are less susceptible to severe infections through intrinsic factors including host-associated skin microbes aiding defense through …

The effects of salinity on the cutaneous microbiome and pathogen infection on the Pacific Tree frog (Pseudacris regilla) in Monterey Bay, California, USA
… saline environments may reduce susceptibility to pathogens such as Batrachochytrium dendrobatidis (Bd). The Moro Cojo Slough State Marine Reserve (MCSSMR) (California, USA) is known as an abundant breeding ground for endangered/threatened amphibian species. To test and expand the salt refuge …

IMPACTS OF BLOODBORNE PATHOGEN INFECTIONS ON BREEDING ECOLOGY AND SUCCESS IN WHITE-THROATED SPARROWS (Zonotrichia albicollis)
<p>Bloodborne pathogens have significant and persistent impacts on avian populations worldwide, including decreased long-term survival and population size. Existing research indicates that chronic pathogen infections may have negative impacts on nesting success, such as decreased numbers of …

Soybean aphid intra-biotype variability based on colonization of specific soybean genotypes, resistance responses of soybean genotypes to pathogen infection after the application of chemical elicitors, and resistance to charcoal rot identified in ancestral soybean germplasm
… under constant threat of disease from invading pathogens and pests. One potential management method is to treat plants with elicitors to induce host resistance. The objective of this research was to determine if elicitors, previously shown to elicit defense responses in other host-pathogen …

Histone Variant H2A.Z Substitution Mediated by the SWR1-like Complex is a Novel Transcriptional Regulatory Mechanism Controlling Defense Genes and Immunity in Plants
… arms race between the host and various pathogens. One of the most vigorous immune responses in plants involves resistance (R) proteins, which detect the presence of effector molecules from pathogens and trigger a large-scale reprogramming in RNA transcription of defense genes. MORC1 is …

Neuronal Regulation of the Innate Immune Response in Caenorhabditis elegans
… the front line of host defense against microbial infections, but its rapid and uncontrolled activation elicits microbicidal mechanisms that have deleterious effects. Increasing evidence indicates that the metazoan nervous system, which responds to stimuli originating from both the internal and the …

Soybean Seed Quality Studies (Scanning Electron-Microscopy, Phomopsis Spp., Alternaria Sp.)
… openings on the seed surface play in field pathogen infection of the seed? (3) Why do male sterile soybeans have poor seed quality? (4) What is the relationship and genetics of reproductive growth stages and specific soybean seed quality traits?

Reversible Germline Dynamics of Caenorhabditis elegans During Exposure to Pathogenic Bacteria
Little is known of how pathogen infection affects reproductive fitness and fecundity in metazoa. Caenorhabditis elegans is a free-living nematode and well-characterized animal model that encounters pathogenic microbes in its natural environment. How these pathogens affect the reproductive capacity …

Pseudoalteromonas sp. strain C4 as a probiotic for farmed South African abalone, Haliotis midae
… the susceptibility of farmed abalone to pathogenic bacterial infection. The mechanism by which the probiotic is able to increase growth rates and reduced susceptibility to pathogen infection was investigated. A number of bacterial strains were isolated from the digestive tract of Haliotis …

The Impact of Iron Deficiency on Plant-Oomycete Interactions
… simultaneously with biotic threats such as pathogens and herbivores. Oomycete pathogens represent a significant threat to global food production and natural ecosystems. Novel modes of oomycete disease control could increase crop yield and reduce pesticide application. Overlaps between the …

HOOKLESS1 REGULATES RESPONSES TO PATHOGENS AND ABSCISIC ACID THROUGH INTERACTION WITH MEDIATOR18 AND ACETYLATION OF WRKY33 AND ABI5 CHROMATIN
… enhanced susceptibility to the necrotrophic pathogen Botrytis cinerea and the hemi-biotrophic pathogen Pseudomonas syringae DC3000 strain expressing the effector protein AvrRpm1 strain. We show that HLS1 modulates the expression of WRKY33 gene, a known defense regulator, as well as ABI5 in …

Determination of class II peptide-MHC repertoires and recognition via large yeast-displayed libraries
… outcomes across diverse maladies including pathogen infection, cancer, autoimmunity, allergies, and transplant rejection. Yet, when properly directed, T cells drive potent protective and therapeutic responses in prophylactic vaccinations and novel immunotherapies. Therefore, understanding …

The role of autophagy in arabidopsis thaliana during biotrophic and hemibiotrophic fungal infections
A plant's response to pathogen infection is tailored dependent on infection strategy. Successful plant pathogens employ various infection strategies to avoid or reduce plant defense responses for the establishment of host compatibility. Autophagy is a non-selective degradation pathway conserved in …

Genetic analysis of innate immunity in Caenorhabditis elegans
Pathogen resistance in Caenorhabditis elegans is a model for studying innate immunity. Several conserved activators in the p38 PMK-1 pathway have been identified and are required for pathogen resistance to the bacterium Pseudomonas aeroginosa. Thus far, screens have been performed to identify …

An investigation into the role of the ubiquitin-proteasome system in plant defence
… response of AtUBP12 and AtUBP13 during pathogen infection. Furthermore, a transient over expression approach was used to investigate possible gain of function phenotypes associated with NtUBP12 (tobacco homologue of AtUBP12 and AtUBP13) activity during Cf-9 triggered HR in tobacco. The …
