Metabolism of Plant Polysaccharides by Leucoagaricus gongylophorus , the Symbiotic Fungus of the Leaf-Cutting Ant Atta sexdens L [PDF]

Applied and Environmental Microbiology, 1998
Atta sexdens L, ante feed on the Fungus they cultivate on cut leaves inside their nests. The fungus, Leucoagaricus gongylophorus, metabolizes plant polysaccharides, such as xylan, starch, pectin, and cellulose, mediating assimilation of these compounds ...

Correction: Enrichment and Broad Representation of Plant Biomass-Degrading Enzymes in the Specialized Hyphal Swellings of Leucoagaricus gongylophorus, the Fungal Symbiont of Leaf-Cutter Ants. [PDF]

PLoS ONE, 2015
Leaf-cutter ants are prolific and conspicuous constituents of Neotropical ecosystems that derive energy from specialized fungus gardens they cultivate using prodigious amounts of foliar biomass.

In vitro culture of Leucoagaricus gongylophorus (Agaricaceae), symbiont fungus of the leaf-cutting ant Atta mexicana (Hymenoptera, Formicidae), using solid and plant-supplemented culture media

Acta Botanica Mexicana
Background and Aims: The mutualism between leaf-cutting ants and the fungus Leucoagaricus gongylophorus is a remarkable instance of insect-fungus symbiosis. In this study, we aimed to make a molecular identification of the L.

Leafcutter ants enhance microbial drought resilience in tropical forest soil. [PDF]

Environ Microbiol Rep
We carried out an eight‐month investigation on a tropical soil microbial community in the aftermath of a severe drought event, which resulted in changes to soil moisture levels and methane emissions. Our study reveals that the leafcutter ant, Atta cephalotes, plays a crucial role in stabilizing the microbial community and enhancing its resilience by ...

Ants manage polyol production to fight fungal antagonists [PDF]

Microbiology Spectrum
The attinas, ants of the Attina subtribe (Formicidae: Myrmicinae), colonize vast areas in the American continent. This impressive fitness depends on culturing mutualistic fungi in their “fungus gardens” to digest biomass.

Low Virulence of the Fungi Escovopsis and Escovopsioides to a Leaf-Cutting Ant-Fungus Symbiosis [PDF]

Frontiers in Microbiology, 2021
Eusocial insects interact with a diversity of parasites that can threaten their survival and reproduction. The amount of harm these parasites cause to their hosts (i.e., their virulence) can be influenced by numerous factors, such as the ecological ...

Beyond defense: microbial modifications of plant specialized metabolites alter and expand their ecological functions. [PDF]

New Phytol
Summary Plant specialized metabolites (PSMs) are compounds that are not involved in primary metabolism but instead confer other roles for the plant host, often related to ecological interactions. In the field of plant–microbe interactions, many PSMs have traditionally been considered for their roles in shaping interactions with pathogens.

Selectively Targeting of Gardeners and Symbiotic Fungus in Leaf-Cutting Ant Colonies Using Essential Oils [PDF]

Insects
Social insect pests such as leaf-cutting ants challenge conventional pest management because effective control must disrupt colony-level organization rather than target individual insects. Colony persistence depends on the mutualistic association between
