Explanation:
PSTV stands for Potato virus X. It is a plant virus that infects potato plants. The structure of the virus is important to understand how it infects the host cell.
Structure of PSTV:
- PSTV has a single stranded RNA genome
- The RNA is not enclosed by a protein coat, which makes it naked
- The virus has a rod-shaped structure
- The size of the virus is approximately 750 nm x 12 nm
Infection Mechanism:
- PSTV enters the host cell through a receptor-mediated endocytosis mechanism
- The RNA genome of the virus is released into the host cell cytoplasm
- The RNA genome then undergoes translation to produce viral proteins
- The viral proteins then assemble to form new virus particles
- The new virus particles are then released from the host cell to infect new cells
Conclusion:
PSTV is a plant virus that has a single stranded RNA genome. The RNA is not enclosed by a protein coat, which makes it naked. The virus has a rod-shaped structure and enters the host cell through receptor-mediated endocytosis. The RNA genome of the virus is then released into the host cell cytoplasm and undergoes translation to produce viral proteins. The viral proteins then assemble to form new virus particles, which are released from the host cell to infect new cells.

The Potato Spindle Tuber Viroid ("PSTVd") was the first viroid to be identified. PSTVd is a small, circular RNA molecule closely related to the Chrysanthemum stunt viroid. All potatoes and tomatoes are susceptible to PSTVd and there is no form of natural resistance.
