BEGOMOVIRUSES Meaning and
Definition
-
Begomoviruses are a group of plant viruses that belong to the family Geminiviridae. These viruses are known to infect a wide range of plants, particularly dicotyledonous plants, and can cause significant damage to agricultural crops worldwide. The name "Begomovirus" is derived from the first identified virus in this group, the Tomato yellow leaf curl virus (TYLCV), which was initially discovered in the begomovirus-infested tomato plants.
Begomoviruses are transmitted from plant to plant by a specific group of insect vectors known as whiteflies, mainly species from the Bemisia tabaci complex. These viruses have a small, circular, single-stranded DNA genome, which is encapsulated in a twinned icosahedral capsid. The genome consists of two components, called DNA-A and DNA-B, which together are required for successful infection and replication.
Symptoms of begomovirus infection vary depending on the host plant species and the specific virus involved. However, common symptoms include stunted growth, yellowing and curling of leaves, vein thickening, fruit deformities, and reduced yield. Begomoviruses are known to cause severe epidemics in many economically important crops, such as tomatoes, peppers, cotton, and beans.
Management of begomoviruses involves various strategies, including the use of insecticides to control the whitefly vectors, planting resistant crop varieties, and practicing good cultural practices, such as crop rotation and removal of infected plants. Ongoing research efforts are focused on understanding the biology and molecular interactions of begomoviruses, as well as developing better control strategies to mitigate their impact on crop production.

Etymology of BEGOMOVIRUSES
The word "Begomoviruses" is a scientific term coined to describe a genus of plant viruses belonging to the family Geminiviridae. The etymology of "Begomoviruses" can be traced back to its Latin roots.
The genus name "Begomovirus" comes from the Latin word "Bego", which means "twins" or "two", and the Latin word "virus", which refers to a poisonous liquid or venom. The term "Begomovirus" was chosen because these viruses possess geminate or twin particles, as they have twinned capsids.
The suffix "-virus" is commonly used in virology to denote a class of viruses. Hence, with the combination of "Bego" and "virus", the term "Begomovirus" was formed to represent the distinguishing characteristics of these plant viruses.
