Show Hint
Stress-induced amino acids:
- Proline: Drought, salinity stress.
- Glycine betaine: Osmoprotectant.
- Glutamine: Nitrogen metabolism.
- Proline: Drought, salinity stress.
- Glycine betaine: Osmoprotectant.
- Glutamine: Nitrogen metabolism.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of plant stress physiology and osmoprotectants.
Step 2: Detailed Explanation:
Proline is an amino acid that accumulates in plants under moisture stress (drought, salinity).
It acts as an osmoprotectant and stress indicator.
It helps in osmotic adjustment, protects proteins, and scavenges reactive oxygen species.
Serine (A), Tryptophan (B), and Glycine (C) are not typically associated with moisture stress.
Thus, the correct answer is proline.
Step 3: Final Answer:
Thus, the amino acid induced during moisture stress is proline, which corresponds to option (D).
