Q. With reference to Southern Rice Black-Streaked Dwarf Virus (SRBSDV) seen in the news recently consider the following statements:
1.The virus is spread by the white-backed plant hopper.
2.The virus is found in the seeds of the infected plants and it is transmitted by seeds.
Which of the statements given above is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: A
Notes:

Statement 1: The mysterious disease resulting in “dwarfing” of rice plants, reported mainly from Punjab and Haryana, has been caused by the Southern Rice Black-Streaked Dwarf Virus (SRBSDV). The virus is spread by the white-backed plant hopper, an insect pest, which injects it while sucking the sap from mostly young plants.

Statement 2: The statement is incorrect. The virus is not found in the seeds collected from the infected plants. The virus is specific to the phloem (plant tissues that transport sugar and organic nutrients from the leaves to other parts) and is not transmitted by seed or grain.
