Which flagellate found in the gut of termites?
Trichonympha is a genus of single-celled, anaerobic parabasalids of the order Hypermastigia that is found exclusively in the hindgut of lower termites and wood roaches. Trichonympha’s bell shape and thousands of flagella make it an easily recognizable cell.
What flagellate exists in a symbiotic relationship with termites?
What type of symbiotic relationship do the two species have? Termites and intestinal flagellates have a mutualistic relationship. The flagellates digest the cellulose in the termites diet. This allows the termites to absorb nutrients, which benefits the termites.
What are termite flagellates?
Abstract. Symbiotic flagellates play a major role in the digestion of lignocellulose in the hindgut of lower termites. Many termite gut flagellates harbour a distinct lineage of bacterial endosymbionts, so-called Endomicrobia, which belong to the candidate phylum Termite Group 1.
What protist lives in the guts of termites?
Trichonympha
Trichonympha is only one of several such protists found in the guts of termites.
How do termites get Trichonympha?
Termites have a symbiotic relationship with Protozoa of the Genus Trichonympha, belonging to the Phylum Parabasalia. The termite by itself could not break down the cellulose in the wood that it ingests since it does not produce enzymes to do this.
What is the relationship between termites and wood?
Termites thrive on a diet of wood thanks to a remarkable biological coexistence involving two other organisms. A symbiotic protist that lives in the guts of these wood-eating insects breaks down cellulose found in plant cell walls. And inside each protist lives beneficial bacteria that assist the metabolic process.
How do termites benefit from protozoa?
The termite benefits from the ability of bacterial symbionts within the protozoa to digest cellulose. The protozoa and the bacterial symbionts benefit by having a protective environment and a constant supply of food from the wood chewing actions of the termite.
What lives inside a termites stomach?
Though termites do feed on cellulose within wood, the termites themselves do not actually digest the wood. Instead, there are microorganisms living inside the termite’s digestive system called protozoa. These protozoa actually break down the wood inside the termite, producing by-products that both organisms can digest.
What lives inside the intestines of termites?
Endosymbionts that live within the intestines of the termite assist in converting the wood into nutrients that the termite is able to digest. One of the several types of endosymbionts that lives inside the termite are single-celled organisms called Trichonympha.
What are 2 examples of commensalism?
Examples of Commensalism
- Remora fish have a disk on their heads that makes them able to attach to larger animals, such as sharks, mantas, and whales.
- Nurse plants are larger plants that offer protection to seedlings from the weather and herbivores, giving them an opportunity to grow.
- Tree frogs use plants as protection.
What was the role of the flagellated protist in the termite gut?
The historic literature is dominated by the role of the flagellated protists in the termite gut and their influence on termite social behavior.
How are Cryptocercus and lower termites related?
Only Cryptocercus and lower termites have a collaborative relationship with flagellates for lignocellulose digestion. The flagellates and their prokaryotic symbionts orchestrate a microbial feeding chain driven by the primary fermentations of carbohydrates to short-chain fatty acids, the major source of energy for the host.
How did proctodeal trophallaxis change the evolution of termites?
From the flagellate point of view, proctodeal trophallaxis was a shift from horizontal to vertical transmission, pushing them from the parasitic to the mutualistic end of the symbiotic spectrum, arguably making this host behavioral change the most critical juncture in the evolutionary trajectory of the termite lineage.
What was the origin of mutualism between termites?
This mandatory interdependence between hosts led to the proposal that termites originated as feeding communities bound by the necessity of exchanging flagellates and only later evolved social care of the brood ( Cleveland, 1926; Cleveland et al., 1934; Lin and Michener, 1972; Wilson, 1975 ).
