Everything about Budding totally explained
Budding (also called
burgeoning) is the formation of a new
organism by the protrusion of part of another organism. This is very common in
plants and
fungi, but may be found in animal as well, such as the
Hydra. Usually, the protrusion stays attached to the primary organism for a while, before becoming free. The new organism is naturally genetically identical to the primary one (a
clone). When
yeast buds, one
cell becomes two cells. When a
sponge buds, a part of the parent sponge falls off and starts to grow into a new sponge. These are examples of
asexual reproduction.
In virology
Budding is the process by which enveloped
viruses acquire their external envelope, often as fragment of the host
cell membrane, which bulges outwards and takes the
virion inside. Because viruses are not alive, the Gag protein is essential for this process. Some viruses hijack the host cell proteins normally involved in
endocytosis to facilitate this process.
This method helps the virus leave the cell without lysing the cell, thereby allowing the cellular machinery to produce more viruses.
In embryology
The term
budding is also applied to the process of
embryo differentiation in which old structures are formed in outgrowth from preexisting parts.
In horticulture
Budding is a process that consist of engrafting the
bud of a plant into another plant, see
Shield budding.
