The presence of protease activity in the rectal fluid of attine ants [PDF]

Journal of Insect Physiology, 1970
The rectal fluid of twenty-two species of ants, including seven species of Attini, seven species of non-attine Myrmicinae, and eight species of Formicinae was assayed for proteolytic enzyme activity. Significant activity was present in the rectal fluid of all of the attines and only in the attines. Some implications of these results are discussed.

AN EVALUATION OF THE POSSIBLE ADAPTIVE FUNCTION OF FUNGAL BROOD COVERING BY ATTINE ANTS

Evolution; International Journal of Organic Evolution, 2012
Fungus-growing ants (Myrmicinae: Attini) live in an obligate symbiotic relationship with a fungus that they rear for food, but they can also use the fungal mycelium to cover their brood. We surveyed colonies from 20 species of fungus-growing ants and show that brood-covering behavior occurs in most species, but to varying degrees, and appears to have ...

Evolutionary patterns of proteinase activity in attine ant fungus gardens [PDF]

BMC Microbiology, 2011
Background Attine ants live in symbiosis with a basidiomycetous fungus that they rear on a substrate of plant material. This indirect herbivory implies that the symbiosis is likely to be nitrogen deprived, so that specific mechanisms may have evolved to ...

Interactions among Escovopsis, Antagonistic Microfungi Associated with the Fungus-Growing Ant Symbiosis [PDF]

Journal of Fungi, 2021
Fungi in the genus Escovopsis (Ascomycota: Hypocreales) are prevalent associates of the complex symbiosis between fungus-growing ants (Tribe Attini), the ants’ cultivated basidiomycete fungi and a consortium of both beneficial and harmful microbes found ...

More diverse than previously thought: a novel Hypocreaceae symbiont from Apterostigma fungus-farming ants [PDF]

IMA Fungus
Fungi in the family Hypocreaceae colonize a wide range of habitats, including the nests of fungus-farming ants (Attini, the “attines”). Although several Hypocreaceae genera are known from attine ant nests, recent studies indicate an even greater ...

Digging into the evolutionary history of the fungus-growing-ant symbiont, Escovopsis (Hypocreaceae) [PDF]

Communications Biology
Symbiotic relationships shape the evolution of organisms. Fungi in the genus Escovopsis share an evolutionary history with the fungus-growing “attine” ant system and are only found in association with these social insects. Despite this close relationship,

Novel killer yeasts and toxins from the gardens of fungus-growing ants [PDF]

Applied and Environmental Microbiology
Killer toxins are proteinaceous antifungal molecules produced by yeasts, with activity against a wide range of human and plant pathogenic fungi. Fungus gardens of attine ants in Brazil were surveyed to determine the presence of killer toxin-producing ...

Male‐biased dispersal in a fungus‐gardening ant symbiosis

Ecology and Evolution, 2021
For nearly all organisms, dispersal is a fundamental life‐history trait that can shape their ecology and evolution. Variation in dispersal capabilities within a species exists and can influence population genetic structure and ecological interactions. In

The molecular phylogenetics of Trachymyrmex Forel ants and their fungal cultivars provide insights into the origin and coevolutionary history of ‘higher‐attine’ ant agriculture

Systematic Entomology, 2019
The fungus‐growing ants and their fungal cultivars constitute a classic example of a mutualism that has led to complex coevolutionary dynamics spanning c. 55–65 Ma.

Embryogenesis in Myrmicine Ants Combines Features of Short Germ-Band Development With a Progressive Mode of Segmentation. [PDF]

J Exp Zool B Mol Dev Evol
Different insect species exhibit remarkable diversity in the developmental trajectories from fertilized eggs to hatching larvae. For three myrmicine ant species, we observe a novel combination of a developmental features: small embryonic primordia, a mode of embryogenesis termed short/intermediate germ‐band development, and progressive establishment of
