NECROTROPH Meaning and
Definition
-
A necrotroph is a type of organism, typically a microorganism or fungus, that obtains its nutrients and energy by feeding on dead or dying organic matter. Unlike other types of organisms that rely on living organisms for sustenance, necrotrophs flourish by decomposing dead tissue or exploiting the weakened host.
Necrotrophs are most commonly found in the field of plant pathology, where they cause various plant diseases. They infiltrate plant cells, triggering a process called necrosis, which results in the death of plant tissues and cells. This occurs as the necrotroph derives nutrients from the decaying plant matter, essentially feeding off the host's remains.
This type of parasitic behavior distinguishes necrotrophs from other pathogens known as biotrophs, which rely on living host cells to survive. Unlike biotrophs, necrotrophs actively kill host cells. They release enzymes and toxins that break down the host's tissue and suppress the plant's defenses, ultimately leading to its demise.
Necrotrophs can be harmful to agriculture and ecosystems as they can cause significant damage to crops, trees, and other plants. The control and management of necrotrophic diseases play a crucial role in agriculture to protect crop yields and ensure sustainable food production.
Understanding the mechanisms employed by necrotrophs and developing strategies to mitigate their negative impacts is an ongoing focus of research in plant pathology and microbiology.

Etymology of NECROTROPH
The word "necrotroph" is derived from two Greek roots. The first part, "necro", comes from the Greek word "nekros" (νεκρός), which means "dead" or "corpse". The second part, "troph", is from the Greek word "trophē" (τροφή), which means "nourishment" or "food". Therefore, "necrotroph" literally translates to "nourishment from dead".
In the context of biology and pathology, the term "necrotroph" refers to a type of organism, typically a fungus or a plant pathogen, that derives its nutrients from dead or decaying material. Necrotrophic organisms invade and kill living tissues in order to feed on the dead cells, contrasting with biotrophic organisms that rely on living host cells for nutrition.
