Plant Pathology

Plant pathology or Phytopathology is the scientific study of plant diseases caused by pathogens or noninfectious agents (e.g. air pollutants, inadequate oxygen, and nutrient excesses and deficiencies). It is concerned with the identification, etiology, disease cycle, economic impact, epidemiology, pathosystem genetics and management of plant diseases.

Host-plant-mediated effects of Nadefensin on herbivore and pathogen resistance in Nicotiana attenuata
The adage from Shakespeare, "troubles, not as single spies, but in battalions come," holds true for "Nicotiana attenuata" (coyote tobacco).

Roles of Arabidopsis WRKY3 and WRKY4 Transcription Factors in Plant Responses to Pathogens
Plant WRKY DNA-binding transcription factors are involved in plant responses to biotic and abiotic responses.

Plant diseases threaten chocolate production worldwide
Chocolate lovers, beware. Each year 20 percent of the cacao beans that are used to make chocolate are lost to plant diseases, but even greater losses would occur if important diseases spread.

Why does an anti-anthrax drug kill plants too?
Scientists at the John Innes Centre (JIC), Norwich (1) have today reported that a very successful antibiotic, which is harmless to humans but lethal to most bacteria, also kills plants.

Food safety begins as vegetables grow
Monitoring vegetables while they are growing is crucial in the prevention of contamination of fresh produce with harmful bacteria such as E. coli and Salmonella.

Shade trees getting 'scorched' by plant disease
Bacterial leaf scorch is severely affecting urban shade trees grown not only to provide shade, but to help clear the air, reduce noise, and improve the aesthetics in many U.S. communities.

Isolation and characterization of a Vitis vinifera transcription factor, VvWRKY1, and its effect on responses to fungal pathogens in transgenic tobacco plants
The aim of this study was to identify components of the grape defence mechanisms, and we focus on a WRKY transcription factor expressed in grape berries because fruits, rich in sugar and other nutrients, provide an ideal target for pathogens.

Elicitor-Mediated Oligomerization of the Tobacco N Disease Resistance Protein
Plant nucleotide binding site–leucine-rich repeat (NBS-LRR) proteins are similar to the nucleotide binding oligomerization domain (NOD) protein family in their domain structure.

Leaf scorch symptoms are not correlated with bacterial populations during Pierce's disease
Xylella fastidiosa (Xf) is a xylem-limited bacterium that lives as a harmless endophyte in most plant species but is pathogenic in several agriculturally important crops such as coffee, citrus, and grapevine

Building disease-beating wheat
Disease resistance genes from three different grass species have been combined in the world's first 'trigenomic' chromosome, which can now be used to breed disease resistant wheat varieties.

Malaria, potato famine pathogen share surprising trait
Two wildly different pathogens — one that infects vegetables, the other infecting humans—essentially use the same protein code to get their disease-causing proteins into the cells of their respective hosts.
