Plant pathology

pH

Plants; Plant pathology

Negative logarithm of the effective hydrogen ion concentration; a measure of acidity (pH 7 is neutral; values less than pH 7, acidic; greater than pH 7, alkaline. )

area under disease progress curve (AUDPC)

Plants; Plant pathology

A measure of the total amount of disease over a period of time, determined from graphs of disease vs. time, which can be used to compare epidemics quantitatively.

secondary infection

Plants; Plant pathology

Infection resulting from the spread of infectious material produced after a primary infection or from secondary infections without an intervening inactive period.

quorum sensing

Plants; Plant pathology

The ability of bacteria to interact with each other through a variety of mechanisms; allows a population of bacteria to behave more like a multicellular organism.

secondary metabolite

Plants; Plant pathology

A compound produced in microbes (e.g., mycotoxins, syringomycins) or plants (e.g., caffeine or nicotine) that is not necessary for normal growth and development.

acid precipitation

Plants; Plant pathology

Precipitation (fog, rain, snow) with a low pH, due to the presence of nitric and sulfuric acid formed by the reaction of air pollutants (N0x and S02) with water.

hypersensitive reaction and pathogenicity (HRP) gene

Plants; Plant pathology

Gene required for elicitation of the hypersensitive (HR) response in resistant plants and causation of disease in susceptible plants; a type of avirulence gene.
