Thick-walled or double-walled asexual resting spore formed from hyphal cells (terminal or intercalary) or by transformation of conidial cells that can function as an overwintering stage.
holoparasite
Plants; Plant pathology
Parasitic flowering plant that lacks chlorophyll (nonphotosynthetic) and must rely totally on the contents of the xylem and the phloem of the host plant, e.g. broomrape (Orobanche spp. )
mosaic
Plants; Plant pathology
Disease symptom characterized by non-uniform coloration, with intermingled normal, light green and yellowish patches, usually caused by a virus; often used interchangeably with mottle.
incomplete dominance
Plants; Plant pathology

polymerase chain reaction (PCR)
Plants; Plant pathology
A technique used to amplify the number of copies of a specific region of DNA in order to produce enough of the DNA for use in various applications uch as identification and cloning.
electron microscope
Plants; Plant pathology
Microscope that uses a focused beam of electrons to produce a greatly enlarged image of minute objects, such as a virus, in the same way that light is used in a compound microscope.
incubation period
Plants; Plant pathology
The time between penetration of a host by a pathogen and the first appearance of disease symptoms; the time during which microorganisms inoculated onto a medium are allowed to grow.
