A botanist is studying the effects of different pathogens on potato plants. She exposes one set of plants to a pathogen having several AVR proteins. She exposes another set of plants to a pathogen having a single AVR protein. What do you expect will be the results of his experiment?

Question 1 options:

Mortality rates will be the same in both sets of plants.

Mortality will be higher in plants exposed to the pathogen having several AVR proteins.

Whichever set of plants has the thinner cuticle will have lower mortality.

Mortality will be higher in plants exposed to the pathogen having a single AVR protein.

Solution

Ans b mortality will be higher in plants exposed to the pathogen having several AVR proteins

Plant disease resistant gene (R) provides it immunity against virulent AVR genes. They recognise ans produce signals in response to them. Larger number of AVR genes will be affected severely.
