Sentinels of disease. Plant resistance genes.
Successful defense against an enemy requires perception of his whereabouts. In the last few years, much progress has been made in delineating the plant molecular sentinels that participate in pathogen identification. This ability is encoded by genetically “hard-wired” information, and is called “innate immunity”. It draws its origins from a phylogenetically ancient form of immunity that is comm...
متن کاملHyperspectral monitoring of chemically sensitive plant sentinels
Automated detection of chemical threats is essential for an early warning of a potential attack. Harnessing plants as bio-sensors allows for distributed sensing without a power supply. Monitoring the bio-sensors requires a specifically tailored hyperspectral system. Tobacco plants have been genetically engineered to de-green when a material of interest (e.g. zinc, TNT) is introduced to their im...
متن کاملBioassays - Critical to Biocontrol of Plant Disease
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...
متن کاملPLANT PATHOGENS AS BIOCONTROL AGENTS INNATn7EHAWAIIANECOSY~S
Several examples, some spectacular, are available of successful applications of weed biocontrol approaches with plant pathogenic agents in agricultural and rangeland situations. The overall percentage rate of success of all such programs attempted cannot yet be documented, however. Both the "mycoherbicide" method, in which large quantities of inoculum are directly applied to target plants, and ...
متن کاملInteractions Between Myxobacteria, Plant Pathogenic Fungi, and Biocontrol Agents
Myxobacteria are gram-negative, unicellular bacteria with rod-shaped vegetative cells. They are unique among prokaryotes for using intercellular communication to engage in cooperative morphogenesis from which they produce fruiting bodies bearing resistant myxospores (5). Thick-walled myxospores are responsible for the survival of myxobacteria under unfavorable conditions such as desiccation, hi...
