A physical map of the heterozygous grapevine 'Cabernet Sauvignon' allows mapping candidate genes for disease resistance
Whole-genome physical maps facilitate genome sequencing, sequence assembly, mapping of candidate genes, and the design of targeted genetic markers.

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.

Hawaii's anthurium growers cope with plant disease
A destructive pathogen is impacting Hawaii's production of anthuriums, a plant known for its heart-shaped flower and leaves

Plant pathologists fighting global threat to wheat supply
A new, highly destructive strain of wheat stem rust is continuing to evolve and has the potential to devastate wheat production worldwide

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.

UGA scientists engineer root-knot nematode resistance
Root-knot nematodes are the most economically important group of plant-parasitic nematodes worldwide.

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.

Disease damages wheat roots, thwarts water uptake
Alterations in irrigation schedules may be needed when wheat streak mosaic infection is suspected in winter wheat crops

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.

Hawaii's anthurium growers cope with plant disease
A destructive pathogen is impacting Hawaii's production of anthuriums, a plant known for its heart-shaped flower and leaves, say plant pathologists

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.

Genome info from 'plant destroyers' could save trees, beans and chocolate
Rapidly evolving genes encode substances that may debilitate plants

Balancing male fertility and disease resistance
An international collaboration of researchers, headed by Dr. Shiping Wang (Huazhong Agricultural University, China) has discovered that a single gene in rice regulates both male fertility and pathogen resistance
