The first peptide to be produced after wounding in the tomato plant is __________.
Show answer & explanation
Correct answer: A
Explanation
Correct Answer:
Systemin
Explanation:
In tomato plants, systemin is the first peptide produced after wounding. It plays a key role in activating the plant’s defense response by triggering the synthesis of defense-related compounds, especially against herbivore attack. Systemin is part of the signaling pathway that leads to the production of jasmonic acid, which further strengthens the plant’s wound response mechanism.
Key Points:
Systemin is the first wound-induced peptide in tomato plants.
It activates plant defense mechanisms.
It triggers the jasmonic acid signaling pathway.
It helps protect plants from herbivore damage.
Additional Facts:
Systemin was one of the first plant peptides discovered to function in signaling.
It is mainly studied in tomato and related species.
Jasmonic acid works downstream of systemin in defense signaling.
Important Questions:
Q1: What is systemin?
Ans: A wound-induced signaling peptide in plants
Q2: Which hormone is activated by systemin?
Ans:Jasmonic acid
Q3: What is the role of systemin?
Ans: To activate plant defense responses after wounding
