Which of the following are produced by plants for defense through an increase in gene expression in response to the presence of a pathogen?

Question

Quizplus · Accepted Answer

PR (pathogenesis-related) proteins are produced by plants in response to the presence of a pathogen, and their expression is increased through upregulation of specific genes.

Answer: B
 Elicitors are molecules produced by pathogens that trigger a plant's defense response, including an increase in gene expression for defense-related proteins.

Answer: C
 Enzymes, such as proteases and chitinases, are produced by plants in response to pathogen attack, and their expression is upregulated through an increase in gene expression.

Answer: D
 PAMPs (pathogen-associated molecular patterns) are molecules produced by pathogens that are recognized by a plant's immune system, leading to an increase in gene expression for defense-related proteins.

Answer: E
 Heat shock proteins are not typically produced by plants in response to pathogen attack. They are instead produced in response to heat stress or other environmental stresses.
