Specialized Fungal Parasites and Opportunistic Fungi in Gardens of Attine Ants

Psyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
Ants in the tribe Attini (Hymenoptera: Formicidae) comprise about 230 described species that share the same characteristic: all coevolved in an ancient mutualism with basidiomycetous fungi cultivated for food. In this paper we focused on fungi other than the mutualistic cultivar and their roles in the attine ant symbiosis.

Bacterial extracts for the control of Atta cephalotes (Hymenoptera: Formicidae) and its symbiotic fungus Leucoagaricus gongylophorus (Agaricales: Agaricaceae)

Revista de Biología Tropical, 2019
Leaf-cutting ants (Atta cephalotes Linnaeus) are one of the main insect pests in Latin America; these ants (along with Acromyrmex sp.) present a unique characteristic amongst ants – the cultivation of the Leucoagaricus gongylophorus Möller (Singer) fungus as a food source.

Escovopsioides as a fungal antagonist of the fungus cultivated by leafcutter ants

BMC Microbiology, 2018
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 ...

Gene expression analysis of carbohydrate catabolism in Leucoagaricus gongylophorus LEU18496

Molecular Omics
Abstract Transcriptomic profiles were obtained by RNA-seq of Leucoagaricus gongylophorus growing on two carbon sources (glucose and cellulose) during different growth phases (exponential and stationary) with the aim of analyzing the variations in metabolism depending on the ...

A mixed community of actinomycetes produce multiple antibiotics for the fungus farming ant Acromyrmex octospinosus

BMC Biology, 2010
Background Attine ants live in an intensely studied tripartite mutualism with the fungus Leucoagaricus gongylophorus, which provides food to the ants, and with antibiotic-producing actinomycete bacteria.

Do Atta sexdens rubropilosa workers prepare leaves and bait pellets in similar ways to their symbiotic fungus?

Sociobiology, 2015
Leaf-cutting ants rely on the obligate symbiosis with a fungus, Leucoagaricus gongylophorus, on which they feed. This fungus garden is maintained preferentially with green leaves in combination with other tissues of plant origin.

Desenvolvimento in vitro do fungo simbionte de Atta sexdens rubropilosa Forel, 1908 (Hymenoptera: Formicidae) em meio de cultura com diferentes extratos vegetais Development in vitro of the symbiotic fungus of Atta sexdens rubropilosa Forel, 1908 (Hymenoptera: Formicidae) in culture medium with different plant extracts

Ciência Rural, 2012
O objetivo deste estudo foi avaliar o desenvolvimento in vitro de Leucoagaricus gongylophorus, fungo simbionte de Atta sexdens rubropilosa, em meio de cultura acrescido com extratos de 24 espécies vegetais.

A Brazilian population of the asexual fungus-growing ant Mycocepurus smithii (Formicidae, Myrmicinae, Attini) cultivates fungal symbionts with gongylidia-like structures.

PLoS ONE, 2014
Attine ants cultivate fungi as their most important food source and in turn the fungus is nourished, protected against harmful microorganisms, and dispersed by the ants.
