Which of the following mechanisms can be used to develop insect-resistant plants by inducing changes in plant epigenetic modifications?

Option: 1

DNA methylation

Option: 2

RNA editing

Option: 3

Histone modification


Option: 4

Protein phosphorylation

Answers (1)


Histone modification refers to the chemical modifications made to histone proteins, which help in regulating gene expression. Epigenetic modifications, such as histone modifications, can play a crucial role in developing insect-resistant plants. By inducing changes in the epigenetic marks on histones, the expression of specific genes involved in plant defense mechanisms can be altered. This can result in increased resistance to insect pests.Hence, option 3 is the correct answer. 

Option 1) is incorrect because  DNA methylation is another epigenetic modification, but it is more commonly associated with gene silencing rather than insect resistance in plants.

Option 2) is incorrect because RNA editing involves altering the nucleotide sequence of RNA molecules, and it is not directly related to inducing changes in plant epigenetic modifications for insect resistance.

Option 4) is incorrect because Protein phosphorylation is a post-translational modification that affects protein function but is not directly linked to plant epigenetic modifications for insect resistance.
