Escovopsioides As a Fungal Antagonist of the Fungus Cultivated by Leafcutter Ants Julio Flavio Osti1 and Andre Rodrigues1,2*
Osti and Rodrigues BMC Microbiology (2018) 18:130 https://doi.org/10.1186/s12866-018-1265-x RESEARCHARTICLE Open Access Escovopsioides as a fungal antagonist of the fungus cultivated by leafcutter ants Julio Flavio Osti1 and Andre Rodrigues1,2* Abstract Background: Fungus gardens of fungus-growing (attine) ants harbor complex microbiomes in addition to the mutualistic fungus they cultivate for food. Fungi in the genus Escovopsioides were recently described as members of this microbiome but their role in the ant-fungus symbiosis is poorly known. In this study, we assessed the phylogenetic diversity of 21 Escovopsioides isolates obtained from fungus gardens of leafcutter ants (genera Atta and Acromyrmex) and non-leafcutter ants (genera Trachymyrmex and Apterostigma) sampled from several regions in Brazil. Results: Regardless of the sample locality or ant genera, phylogenetic analysis showed low genetic diversity among the 20 Escovopsisoides isolates examined, which prompted the identification as Escovopsioides nivea (the only described species in the genus). In contrast, one Escovopsioides isolate obtained from a fungus garden of Apterostigma megacephala was considered a new phylogenetic species. Dual-culture plate assays showed that Escovopsioides isolates inhibited the mycelium growth of Leucoagaricus gongylophorus, the mutualistic fungus cultivated by somes species of leafcutter ants. In addition, Escovopsioides growth experiments in fungus gardens with and without ant workers showed this fungus is detrimental to the ant-fungus symbiosis. Conclusions: Here, we provide clues for the antagonism of Escovopsioides towards the mutualistic fungus of leafcutter ants. Keywords: Hypocreales, Attine ants, Escovopsis,Symbiosis Background garden. In fact, a diverse and rich microbial community Fungus-growing ants in the tribe Attini are found only on consisting of bacteria, yeasts, and filamentous fungi are also the American continent [1]. -

Etolog{a, Vol. 5, 1997 Behavioral ecology of mating and colony founding in the grass-cutting ant, Acromyrmex balzani (Hymenoptera: Formicidae) Harold G. Fowler* Reproductive behavior of Acromyrmex balzani ABSTRACT. Behavioral ecology of mating and colony founding in the grass-cutting ant, Acromyrmex balzani (Hymenoptera: Formicidae). - The grass-cutting ant Acromyrmex balzani conducts nuptial flights at dusk, often during light rain. The daily timing of flights is invariant, but annual occurrence is dependent upon meterological conditions. Males form aggregations over shrubs or other prominent objects, into which females fly to be mated. These aggregation sites are used perennially. Sexual com petition among males is intense, with an average of 4 males simultaneously competing foraccess to each female in a mating ball. Multiple matings of females are common. The male genetial capsule is detat ched and retained in the female genetalia upon mating, and femalesremove these prior to flying to mate again. Females found colonies independently and are not claustral. KEY WORDS: Acromyrmex balzani; behaviour; mating; sexual competition; haplometrosis; colony founding; sex-ratio Introduction formation of leks in the male-aggregation syndrome is also common (Holldobler & Wilson, 1990). Boomsma and Leusink ( 1981) demonstrated that, in Mating behaviour in ants is still poorly spite of the diel rhythmicity of nuptial flights, cli documented.

Antagonistic Bacterial Interactions Help Shape Host-Symbiont Dynamics Within the Fungus-Growing Ant-Microbe Mutualism

Within mutualistic associations, the expression and regulation of conflict is likely more complex than in intraspecific cooperative relationship, because of the potential presence of: i) multiple genotypes of microbial species associated with individual hosts, ii) multiple species of symbiotic lineages forming cooperative partner pairings, and iii) additional symbiont lineages. Here we explore complexity of conflict expression within the ancient and coevolved mutualistic association between attine ants, their fungal cultivar, and actinomycetous bacteria (Pseudonocardia). -
Population Genetic Signatures of Diffuse Co-Evolution Between Leaf
Molecular Ecology (2007) 16, 209–216 doi: 10.1111/j.1365-294X.2006.03134.x PopulationBlackwell Publishing Ltd genetic signatures of diffuse co-evolution between leaf-cutting ants and their cultivar fungi A. S. MIKHEYEV,* U. G. MUELLER* and J. J. BOOMSMA† *Section of Integrative Biology, 1 University Station C0930, University of Texas, Austin, TX 78712, USA, †Institute of Biology, Department of Population Biology, University of Copenhagen, Universitetsparken 15, DK-2100 Copenhagen, Denmark Abstract Switching of symbiotic partners pervades most mutualisms, despite mechanisms that appear to enforce partner fidelity. To investigate the interplay of forces binding and dissolving mutualistic pairings, we investigated partner fidelity at the population level in the attine ant–fungal cultivar mutualism. The ants and their cultivars exhibit both broad-scale co-evolution, as well as cultivar switching, with short-term symbiont fidelity maintained by vertical transmission of maternal garden inoculates via dispersing queens and by the elimination of alien cultivar strains. Using microsatellite markers, we genotyped cultivar fungi associated with five co-occurring Panamanian attine ant species, representing the two most derived genera, leaf-cutters Atta and Acromyrmex. Despite the presence of mech- anisms apparently ensuring the cotransmission of symbiont genotypes, different species and genera of ants sometimes shared identical fungus garden genotypes, indicating wide- spread cultivar exchange. The cultivar population was largely unstructured with respect to host ant species, with only 10% of the structure in genetic variance being attributable to partitioning among ant species and genera. Furthermore, despite significant genetic and ecological dissimilarity between Atta and Acromyrmex, generic difference accounted for little, if any, variance in cultivar population structure, suggesting that cultivar exchange dwarfs selective forces that may act to create co-adaptive ant–cultivar combinations. -

The leaf-cutting ants of the genus Acromyrmex attack mainly leaves of vegetables and fruit trees exposing not only to the agrochemicals used for their control as well as to those used for the control of other pests. Due to the bioindicator potential of environmental quality of the ants and their frequent exposure to agrochemicals such as organophosphates, neonicotinoids and growth regulators insecticide used for pest control, it is necessary to study the sublethal effects that these pesticides may cause. -
