What are the symptoms of virus in plants?

What are the symptoms of virus in plants?

Symptoms of virus infection include necrotic spots, abnormal dark green and light green mosaic and mottling of leaves, growth distortion, stunting, ring patterns or bumps on plant foliage, and abnormal flower coloration and formation. Plants may also be infected with more than one virus or viral strain.

What are the main characteristics of a plant virus?

Virus is a submicroscopic, transmissible, intercellular, obligate parasite and consists of nucleic acid (either RNA or DNA), which is typically surrounded by a protein coat. They are less than 200 millimicron and cannot be grown in artificial media and require living host cell for multiplication.

What are the possible signs of a virus and viroid in plants?

Expression of commonly observed symptoms of viroid infection — stunting, leaf epinasty and distortion, fruit distortion and color break, stem and leaf necrosis, and even death of the whole plant — is often dependent upon environmental conditions. Also, many viruses can cause very similar symptoms.

What are 5 characteristics of viruses?

These are: 1) attachment; 2) penetration; 3) uncoating; 4) replication; 5) assembly; 6)release. As shown in , the virus must first attach itself to the host cell. This is usually accomplished through special glycoprotiens on the exterior of the capsid, envelope or tail.

Who is the father of viruses?

Martinus Beijerinck
Martinus Beijerinck is often called the Father of Virology. Beijerinck’s laboratory grew into an important center for microbiology.

Which disease is caused by virus?

Viruses cause familiar infectious diseases such as the common cold, flu and warts. They also cause severe illnesses such as HIV/AIDS, Ebola, and COVID-19. Viruses are like hijackers. They invade living, normal cells and use those cells to multiply and produce other viruses like themselves.

What are examples of symptoms?

A physical or mental problem that a person experiences that may indicate a disease or condition. Symptoms cannot be seen and do not show up on medical tests. Some examples of symptoms are headache, fatigue, nausea, and pain.
