- the
aeciospores penetrate the gr****,
leading to the
production of
uredia. The
uredia produce urediniospores capable of
infecting more gr**** plants. Ultimately...
- turn a reddish-brown color. The
uredia develop underneath the
epidermis where the leaf
spots are present. When the
uredia become big enough, they break...

infect the
primary host. II-Urediniospores from
Uredia (Uredinia).
These serve as

- wind-blown
aeciospores infect Ribes spp. and the
fungus quickly develops uredia in less than a few w****s.
Uredospores produced in this

spores can
either reinfect gr****es by
spreading uredospores that
become uredia which leads to more
uredospores and a
likely epidemic; or they can become...
