How do plant viruses replicate?
Many plant viruses replicate in association with the cortical ER-actin network that is continuous between cells through plasmodesmata. The replication complexes can be highly organized and supported by network interactions between the viral genome and the virus-encoded proteins.
What are the 2 types of replication in viruses?
There are two processes used by viruses to replicate: the lytic cycle and lysogenic cycle. Some viruses reproduce using both methods, while others only use the lytic cycle. In the lytic cycle, the virus attaches to the host cell and injects its DNA.
What are the 4 steps for active virus replication?
Step 1: Attachment: The virus attaches itself to the target cell. Step 2: Penetration: The virus is brought into the target cell. Step 3: Uncoating and Replication: The enveloped virus loses its envelope, and viral RNA is released into the nucleus, where it is replicated. Step 4: Assembly: Viral proteins are assembled.
How are plant viruses adapted to their hosts?
Viruses adapt to their hosts by evading defense mechanisms and taking over cellular metabolism for their own benefit. Alterations in cell metabolism as well as side-effects of antiviral responses contribute to symptoms development and virulence.
How do plant viruses get multiplied in plants?
Viruses replicate using both their own genetic information and host cell components and machinery. The different genome types have different replication pathways which contain controls on linking the process with translation and movement around the cell as well as not compromising the infected cell.
Do all viruses replicate the same way?
Replication between viruses is greatly varied and depends on the type of genes involved in them. Most DNA viruses assemble in the nucleus while most RNA viruses develop solely in cytoplasm.
Can you get a virus from eating plants?
Eating or touching infected plants or their parts would not likely infect us with the same pathogen that is making the plant sick.
