Plant pathologists detect syndromes directly with the naked eye. However, such detection usually requires continuous monitoring, which is time overwhelming and very expensive on large farms. The disease diagnosis is limited by the human’s visual abilities because most of the first symptoms are microscopic. Therefore, seeking rapid, automated, economical, and accurate methods of plant syndrome d...

The coevolution of interacting plants and microbes has given rise to a diverse array of exchanged signals and responses. Microbes that elicit a host response can be met variously with hospitable acceptance (as is the case with symbionts such as nitrogen-fixing Rhizobium bacteria), with tardy recognition and moderately effective defenses (as for most interactions that result in disease), or with...

Plant diseases cause significant reductions in agricultural productivity worldwide. Disease symptoms have deleterious effects on the growth and development of crop plants, limiting yields and making agricultural products unfit for consumption. For many plant-pathogen systems, we lack knowledge of the physiological mechanisms that link pathogen infection and the production of disease symptoms in...

Plant breeders have used disease resistance genes (R genes) to control plant disease since the turn of the century. Molecular cloning of R genes that enable plants to resist a diverse range of pathogens has revealed that the proteins encoded by these genes have several features in common. These findings suggest that plants may have evolved common signal transduction mechanisms for the expressio...

Transcriptional reprogramming is critical for plant disease resistance responses; its global control is not well understood. Salicylic acid (SA) can induce plant defense gene expression and a long-lasting disease resistance state called systemic acquired resistance (SAR). Plant-specific "Whirly" DNA binding proteins were previously implicated in defense gene regulation. We demonstrate that the ...

Bioassays are frequently used by plant pathologists for studies related to disease resistance. fungicides, nematicides, and biocontrol agents. Their use was perfected with the development of chemical control agents. Bioassays were standardized as a result of cooperation among individuals. committees, industry and professional societies. Bioassays for biocontrol of plant disease have not been ex...
