Cooperation, conflict, and coevolution in the attine ant-fungus symbiosis [PDF]

Behavioral Ecology, 2005
Fungus-growing ants in the tribe Attini represent a classic example of a mutualism. These ants obligately depend on fungus as their major food source, while the fungus receives both vegetative substrate (nourishment) from the ants and protection from pathogens. Here, we try to identify both benefits and costs of the association by using cultivar switch

Genome analysis of two Pseudonocardia phylotypes associated with Acromyrmex leafcutter ants reveals their biosynthetic potential [PDF]

, 2016
The attine ants of South and Central America are ancient farmers, having evolved a symbiosis with a fungal food crop >50 million years ago. The most evolutionarily derived attines are the Atta and Acromyrmex leafcutter ants, which harvest fresh leaves to

Chemical ecology of antibiotic production by actinomycetes [PDF]

, 2017
Actinomycetes are a diverse family of filamentous bacteria that produce a plethora of natural products relevant for agriculture, biotechnology and medicine, including the majority of the antibiotics we use in the clinic.

Antagonistic bacterial interactions help shape host-symbiont dynamics within the fungus-growing ant-microbe mutualism. [PDF]

PLoS ONE, 2007
Conflict within mutually beneficial associations is predicted to destabilize relationships, and theoretical and empirical work exploring this has provided significant insight into the dynamics of cooperative interactions. Within mutualistic associations,

Expansion of the geographic range of Cyatta abscondita Sosa-Calvo et al., 2013 (Hymenoptera: Formicidae) [PDF]

, 2016
The presence of the recently described fungus-farming ant genus and species Cyatta abscondita is reported in the northwestern region of Misiones Province in Argentina. A single worker of C.

Quality and quantity: transitions in antimicrobial gland use for parasite defense [PDF]

, 2015
Parasites are a major force in evolution, and understanding how host life history affects parasite pressure and investment in disease resistance is a general problem in evolutionary biology.

Eggs of the Blind Snake, Liotyphlops albirostris, Are Incubated in a Nest of the Lower Fungus-Growing Ant,  Apterostigma cf. goniodes

Psyche: A Journal of Entomology, 2012
Parental care is rare in most lower vertebrates. By selecting optimal oviposition sites, however, mothers can realize some benefits often associated with parental care. We found three ovoid reptilian eggs within a mature nest of a relatively basal fungus-

Leaf-cutting ant fungi produce cell wall degrading pectinase complexes reminiscent of phytopathogenic fungi

BMC Biology, 2010
Background Leaf-cutting (attine) ants use their own fecal material to manure fungus gardens, which consist of leaf material overgrown by hyphal threads of the basidiomycete fungus Leucocoprinus gongylophorus that lives in symbiosis with the ants ...

Chemical warfare between leafcutter ant symbionts and a co-evolved pathogen [PDF]

, 2018
Acromyrmex leafcutter ants form a mutually beneficial symbiosis with the fungus Leucoagaricus gongylophorus and with Pseudonocardia bacteria. Both are vertically transmitted and actively maintained by the ants.

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.
