What are role of toxins in plant disease?

The toxin (com- posed of ten linear polyketols) affects leaf func- tion, including photosynthesis and respiration, and inhibits closure of stomata. In addition, membrane permeability is increased, resulting in leakage of potassium, and root growth is also impared.

Which virulent fungal disease affects wheat?

Wheat leaf rust is a fungal disease that affects wheat, barley and rye stems, leaves and grains. In temperate zones it is destructive on winter wheat because the pathogen overwinters. Infections can lead up to 20% yield loss, which is exacerbated by dying leaves, which fertilize the fungus.
