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 ...

Sclerotia Questions
... answer here Submit Answer 2 Answer 2 Very little difference exists. Stromata commonly form in host tissue, and therefore may incorporate plant cells. However, all stromata form fruiting bodies at the completion ... fungi require moisture, while some plant pathogens require a specific molecule released by a potential host plant. Top Question 4 There are no further questions for this topic. Type your ...
