Which are called as rusts and smuts?

Rusts and smuts are fungi belonging to the orders Urediniales (rusts) and Ustilaginales (smuts) which are basidiomycete fungi. The rusts have complicated life cycles which involve the infection of two different plant species.

How are Rusts and smuts different from other Basidiomycetes?

While rust fungi require two different hosts to complete their life cycle, smut fungi may complete their life cycle on only one host, which is always a flowering plant. Another difference between rust and smut fungi is seen in the way that they infect their host plants.

What is difference between rust and corrosion?

Corrosion is the process by which certain materials, metals and non-metals, deteriorate as a result of oxidation. Rusting is oxidation of iron in the presence of air and moisture. Corrosion can occur on materials such as ceramics or polymers. Rusting occurs on surfaces of iron and its alloys.

What is an example of rust?

Rust is a reddish-brown or reddish-yellow color that coats iron or steel when exposed to air and moisture. An example of rust is what happens to the chain on a bike that’s been left out in the rain all winter.

What is the difference between a Basidium and ascus?

The ascus is a sac-like structure that bears reproductive cells. These cells produce sexual spores. Basidium is a club-shaped structure having sexual cells that produce sexual spores.

What is rust botany?

Rusts are plant diseases caused by pathogenic fungi of the order Pucciniales (previously known as Uredinales). Rust fungi are obligate plant pathogens that only infect living plants. Infections begin when a spore lands on the plant surface, germinates, and invades its host.

What is corrosion Vedantu?

Hint: Corrosion is an irreversible reaction of a metal with the components of the environment. The corrosion of a metal is defined as a natural process that converts a refined metal into a more chemically stable form such as oxide, hydroxide, or sulphide.

What is corrosion BYJU’s?

The formation of this layer is the result of a chemical process known as rusting, which is a form of corrosion. Cossorion, in general, is a process through which refined metals are converted into more stable compounds such as metal oxides, metal sulfides, or metal hydroxides.

What is corrosion Byjus?

What is the common example of corrosion?

Rusting of iron and steel is perhaps the most common example of metallic corrosion. There are many well-known examples such as the rusting of exhaust systems and bodies of cars, water pipes and various types of structural steel-work. There are other examples of corrosion in everyday life.

What are Ascomycetes and Basidiomycetes?

Ascomycota (sac fungi) form spores in sacs called asci during sexual reproduction. Asexual reproduction is their most common form of reproduction. Basidiomycota (club fungi) produce showy fruiting bodies that contain basidia in the form of clubs. Spores are stored in the basidia.

What is Perithecium and Cleistothecium?

is that cleistothecium is (biology) a closed ascocarp, in some fungi, from which spores are released following decay or disintegration while perithecium is an ascocarp shaped like a skittle or ball, distinguished by a small pore, the ostiole, through which the spores are released one by one when ripe.

What is rust rusts?

Rusts: A plant disease caused by a fungus of the class uredinomycetes. The characteristic symptom is the development of spots or pustules bearing masses of powdery spores which are usually rust coloured, yellow, or brown. Infected plants may also show distortions or gall like also distortions or gall like swellings.

What is the life cycle of rusts?

The rusts have complicated life cycles which involve the infection of two different plant species. The most well-known members of these groups are wheat rust (Puccinia graminis tritici) and corn smut (Ustilago myadis). Rust fungi attack plants such as ferns, gymnosperms, and flowering plants.

What are some examples of Rust in plants?

Some of the examples of rust are wheat stem rust, white pine blister rust, soybean rust, coffee rust, etc.; these are economically important crops that are affected by rust. All of the rusts are parasites and they require a living host for completion of the life cycle and here, they can severely rescue the yield and growth of the host plant.

What is the nutrition intake for rust?

The nutrition intake for rust is intercellular using structures called haustoria. The intake of nutrition for smuts can either be intercellular or intracellular. Clamp connect is present but rare. Clamp connections are commonly observed in smuts.
