हिन्दीA crop plant exhibits severe developmental abnormalities including leaf rolling, curling, yellowing, vein clearing, dwarfing, and stunted growth. What is the pathogen responsible for these symptoms, and what is its chemical composition?
Correct answer · Option 4
A nucleoprotein virus composed of genetic material surrounded by a protective protein coat
