Plant Pathology: Plant Diseases Overview
... host tissue, wilting, abnormal growth and differentiation and discolouration of host tissue. Some parasites, called necrotrophs, secrete enzymes that kill host tissue, extract nutrients from the cells and then live in the dead tissue ... with water conduction within the plant (i.e. infection of the vascular tissue), or loss of control of transpiration. Abnormal growth and differentiation results from ...

Plant Pathology: Infection Process
... host tissue, a spore must germinate and grow on the surface of the plant. In the case of motile pathogens, they must find the host and negotiate its surface before entering the host ... all tissues. Some downy mildews can also systemically infect their host by invading the vascular tissue and growing throughout the host, causing deformation, rather than necrosis. Finally, there are some pathogens ...

Verticillium Wilt of Strawberry, HYG-3012-95
... to differentiate from those caused by other root infecting fungi. Isolation from diseased tissue and culturing the fungus in the laboratory are necessary for positive disease identification ... tissue. The destruction of water-conducting tissue results in reduced water uptake by the plant; thus, the plants wilt and wither. As fungal colonies get older they produce microsclerotia in infected host tissue ...

Black Root Rot of Greenhouse Floral Crops, HYG-3066-96
... There are also methods to culture the fungus from the tissue. Since the pathogen grows slowly onto the culture plate, ... the fungus is very common and widespread. It has a wide host range and affects many other hosts besides greenhouse floral crops ... or nearly so. Thielaviopsis produces resistant "resting" spores on infected host tissue in tremendous numbers. These spores can be splashed about or ...
