Gymnosporangium juniperi-virginianae is a plant pathogen that causes cedar-apple rust. [1] In virtually any location where apples or crabapples and eastern red cedar (Juniperus virginiana) coexist, cedar apple rust can be a destructive or disfiguring disease on both the apples and cedars.
In other species, such as in G. clarvariforme, the telia are produced directly from the bark of the juniper with no obvious gall formation or swelling. [4] The basidiospores are released and travel on the wind until they infect an apple, pear, hawthorn or suitable tree. On the secondary hosts, the fungus produces yellowish depressions on the ...
Gymnosporangium sabinae is a species of rust fungus in the subdivision Pucciniomycotina.Known as pear rust, European pear rust, or pear trellis rust, it is a heteroecious plant pathogen with Juniperus sabina (savin juniper) as the main primary host and Pyrus communis (common pear) as the main secondary host.
However, leaf spots may, in advanced stages, expand to kill entire areas of leaf tissue and thus exhibit blight symptoms. Blights are often named after their causative agent. For example, Colletotrichum blight is named after the fungus Colletotrichum capsici, and Phytophthora blight is named after the water mold Phytophthora parasitica. [11]
