Plant Pathogens Many of the fungi are pathogens that infect plants and animals causing diseases of many kinds. The  life cycles of many of these are complex and involve two or more host plants. Rusts The  rusts  are specialized basidiomycetes that are parasites on plants. They have complex life  cycles, and some produce five different kinds of spores in addition to basidiospores. Many rusts are  heteroecious  and complete their life cycles on two different kinds of host plants whereas  autoecious  parasites produce all of their different kinds of spores on a single host species. Well- known examples of heteroecious rusts are wheat rust, white pine blister rust, and cedar-apple rust.  Smuts Smuts are parasitic basidiomycetes that produce powdery masses of black spores enclosed in a

Unformatted text preview: membrane. This membrane is often found in the ovaries of species of grasses, or on their leaves. The smut life cycle is less complex than that of the rusts, and only one other kind of spore in addition to basidiospores is produced. All smuts complete their life cycle on only one kind of plant. Smuts live as saprobes in the soil, however, and readily attack developing seedlings planted in infected soil. Corn smut is common in the Midwest. Despite the unappetizing appearance of the spore masses and their dust-like texture, membrane-enclosed corn smut spore masses are considered delicacies in some cultures and are eaten either boiled or fried....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
