Tetraponera ants have gut symbionts related to nitrogen-fixing root-nodule bacteria.
Some Tetraponera ants (Formicidae, Pseudomyrmecinae) subsist almost entirely on amino acid deficient honeydew secretions of pseudococcids and harbour a dense aggregation of bacterial symbionts in a unique pouch-shaped organ at the junction of the midgut and the intestine. The organ is surrounded by a network of intruding tracheae and Malpighian tubules, suggesting that these bacteria are involv...
متن کاملBacterial gut symbionts are tightly linked with the evolution of herbivory in ants.
Ants are a dominant feature of terrestrial ecosystems, yet we know little about the forces that drive their evolution. Recent findings illustrate that their diets range from herbivorous to predaceous, with "herbivores" feeding primarily on exudates from plants and sap-feeding insects. Persistence on these nitrogen-poor food sources raises the question of how ants obtain sufficient nutrition. To...
متن کاملInvestigation of the Effect of Exhaust Gas Recirculation (EGR) on pollutants Emission From Si Engine Exhaust Gasese (RESEARCH NOTES)
This paper reports the results of an experimental investigation on the effect of the EGR on the pollutants emission, especially on oxides of nitrogen, from the exhaust gases and performance of the spark ignition engine. Also along with experimental work, a mathematical model for the determination of the effect of EGR on the peak cycle temperature and for the prediction of its effect on the NOx ...
متن کاملAncient tripartite coevolution in the attine ant-microbe symbiosis.
The symbiosis between fungus-growing ants and the fungi they cultivate for food has been shaped by 50 million years of coevolution. Phylogenetic analyses indicate that this long coevolutionary history includes a third symbiont lineage: specialized microfungal parasites of the ants' fungus gardens. At ancient levels, the phylogenies of the three symbionts are perfectly congruent, revealing that ...
متن کاملCloning of conserved regions of nontypeable Haemophilus influenzae hmw1 core binding domain
Colonization of nontypeable Haemophilus influenzae (NTHi) in nasopharynx causes respiratory tract disease. In 80% of clinical isolates, HMW proteins are the major adhesions and induce protective antibodies in the hosts. Therefore, it can be used as a vaccine candidate. The aim of this study is designing and cloning of the conserved regions of NTHi hmw1 core binding domain.In this study, the sta...
