GEMINIVIRUSES Meaning and
Definition
-
Geminiviruses are a family of plant viruses that belong to the genus Begomovirus. They are characterized by their distinct geminate (twin) particle structure, which consists of two incomplete particles that combine to form a complete, icosahedral-shaped virus. These viruses have a small, circular, single-stranded DNA genome that is encapsidated within the particles.
Geminiviruses primarily infect plants, causing a wide range of diseases in both monocotyledonous (grasses) and dicotyledonous (non-grass plants) species. They are transmitted by insect vectors, such as whiteflies or leafhoppers, which feed on infected plants and acquire the virus particles. The virus particles can then be transmitted to healthy plants when the insect vectors feed on them.
The symptoms caused by geminiviruses vary depending on the viral species and the infected plant host. Common symptoms include stunted growth, leaf curling, chlorotic mottling (yellowing) of leaves, and abnormal development of flowers and fruits. These diseases can significantly reduce crop yield and quality, posing a threat to agricultural production.
Control measures for geminivirus infections include the use of resistant plant varieties, good management practices to prevent insect vectors, and the application of insecticides when necessary. Research efforts are ongoing to develop virus-resistant plant varieties and explore other strategies to manage geminivirus diseases effectively.
Overall, geminiviruses are an important group of plant viruses that can cause significant economic losses in agriculture. Understanding their biology, transmission, and management is essential for protecting crops and ensuring food security.

Etymology of GEMINIVIRUSES
The word "Geminiviruses" is derived from the Latin word "geminus", which means "twin" or "double". This name was chosen because the viruses in this family have a distinct twinned appearance under an electron microscope. The viruses exhibit a unique twinned particle structure consisting of two incomplete icosahedral capsids. Hence, the term "Geminiviruses" was coined to describe this family of plant viruses characterized by their twin-like structure.
