Phylogenomic reconstruction reveals new insights into the evolution and biogeography of Atta leaf‐cutting ants (Hymenoptera: Formicidae)

open access: yesSystematic Entomology, Volume 47, Issue 1, Page 13-35, January 2022., 2022
We employ phylogenomic markers (UCEs) to reconstruct the most extensively sampled phylogeny to date for the ecologically dominant leaf‐cutting ant genus Atta, the major herbivore of the New World tropics. The ancestor of Atta arose 8.5 Ma in the North/Central America + NW South America range, and its descendant species rapidly radiated into Neotropical

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

open access: yesPLoS 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.

Three phylogenetically distinct and culturable diazotrophs are perennial symbionts of leaf‐cutting ants

open access: yesEcology and Evolution, Volume 11, Issue 24, Page 17686-17699, December 2021., 2021
In leaf‐cutting ant pests, an obligate mutualistic basidiomycete mediates the ants’ nutrition with carbons from vegetal matter using a fermenter‐like system inside the nest, called a “fungus garden.” Diazotrophs such as Enterobacteriales in the fungus garden and intestinal Rhizobiales were proposed to mediate the incorporation of atmospheric nitrogen ...

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

open access: yesBMC 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.

Disease management in two sympatric Apterostigma fungus‐growing ants for controlling the parasitic fungus Escovopsis

open access: yesEcology and Evolution, Volume 11, Issue 11, Page 6041-6052, June 2021., 2021
We studied two sympatric Apterostigma fungus‐growing ants (Attini) species and their symbiotic fungal cultivars which are attacked by multiple morphotypes of parasitic fungi in the genus, Escovopsis. We assessed in vitro and in vivo interactions of these parasites with their hosts to understand, in the context of a multihost, multiparasite system, the ...

Reconstructing the functions of endosymbiotic Mollicutes in fungus-growing ants

open access: yeseLife, 2018
Mollicutes, a widespread class of bacteria associated with animals and plants, were recently identified as abundant abdominal endosymbionts in healthy workers of attine fungus-farming leaf-cutting ants.

Development, characterization, and cross-amplification of polymorphic microsatellite markers for North American Trachymyrmex and Mycetomoellerius ants

open access: yesBMC Research Notes, 2020
Objective The objective of this study is to develop and identify polymorphic microsatellite markers for fungus-gardening (attine) ants in the genus Trachymyrmex sensu lato.

New light on the systematics of fungi associated with attine ant gardens and the description of Escovopsis kreiselii sp. nov. [PDF]

open access: yesPLoS ONE, 2015
Since the formal description of fungi in the genus Escovopsis in 1990, only a few studies have focused on the systematics of this group. For more than two decades, only two Escovopsis species were described; however, in 2013, three additional Escovopsis ...

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

open access: yesBehavioral 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

Yet more "weeds" in the garden: fungal novelties from nests of leaf-cutting ants. [PDF]

open access: yesPLoS ONE, 2013
Symbiotic relationships modulate the evolution of living organisms in all levels of biological organization. A notable example of symbiosis is that of attine ants (Attini; Formicidae: Hymenoptera) and their fungal cultivars (Lepiotaceae and Pterulaceae ...
