Question

In Puccinia graminis tritici , Teleutospores and Pycniospores are produced on plants respectively
a) Wheat and Barberry
b) Barberry and Wheat
c) Wheat and Barley
d) Barberry and Barley

Answer 1

The fungus Puccinia graminis causes stem, black, and cereal rusts, which are serious diseases that damage cereal crops. Cereal farming has been afflicted by these diseases for millennia.

Complete answer:
The wheat plant is a primary host for Teleutospores.
Pycniospores' primary host is the barberry plant, which occurs in late winter.
Rhynchospora has an impact on Barley.
As a result, the correct answer is 'Wheat and Barberry.'
Puccinia graminis causes stem rust in a variety of oats, including wheat, rye, and oat. Wheat confinement cannot contaminate oat or another host, and vice versa, demonstrating their host specificity. Organic specialisation refers to the phenomenon in which a specific microorganism contaminates only one host. The species graminis is divided into various natural strains, natural structures, and subspecies based on the aforementioned phenomenon.
Mycelium is the vegetative body. Mycelia are classified into two types: dikaryotic and monokaryotic. Both types are septate, much larger, develop intercellularly, and produce exceptional haustoria that enter the host cell.
The dikaryotic mycelium occurs in the wheat plant, which serves as the microbe's essential host, and the monokaryotic mycelium occurs in the barberry plant, which serves as the microbe's substitute host.

Note:
If present in the septum, the basic pore maintains protoplasmic progression between neighbouring cells. Chitin and glucan are used to make the cell divider. The cytoplasm also contains vacuoles, oil globules, glycogen bodies, and other structures.
