Signaling compound involved in SAR is

A. Jasmonic acid

B. Ethylene

C. Salicyclic acid

D. Both A and B

Answer: Option D

Solution(By Examveda Team)

The signaling compound involved in SAR is Jasmonic acid and Ethylene.
SAR requires the signal molecule salicylic acid (SA) and is associated with the accumulation of pathogenesis-related proteins, which are thought to contribute to resistance.
SA signaling confirmed the role of SA as an important signal in SAR. In addition, in transgenic tobacco and Arabidopsis plants, overproduction of SA enhanced the resistance to pathogens.
