Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
The question asks to identify the specific host tree of the "Spike Disease," a significant pathological condition in forestry.
Detailed Explanation:
• Sandal Spike Disease (SSD):
Spike disease is a devastating condition affecting Santalum album (Indian Sandalwood).
It is caused by Phytoplasmas, which are specialized bacteria without cell walls that live in the plant phloem.
• Symptoms:
The disease causes a severe reduction in leaf size, shortening of internodes, and a "spiky" or "broom-like" appearance of the branches. The affected trees usually die within 1-3 years.
• Analyzing other options:
Tectona grandis is Teak.
Cedrus deodara is Deodar Cedar.
Corymbia citriodora is Lemon-scented Gum (Eucalyptus).
Step 2: Final Answer:
Spike disease is a characteristic and destructive disease of the Sandalwood tree (Santalum album).

- Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): The disruption of $\beta$-oxidation of fatty acids in plants can potentially reduce stress-induced ROS accumulation and improve its stress tolerance.
Reason (R): In plants, $\beta$-oxidation of fatty acids takes place predominantly in peroxisomes, where first enzyme of $\beta$-oxidation viz. fatty acyl CoA oxidase produces large amounts of hydrogen peroxide.
