Comparative FISH-mapping of TTAGG telomeric sequences to the chromosomes of leafcutter ants (Formicidae, Myrmicinae): is the insect canonical sequence conserved? [PDF]
Comparative Cytogenetics, 2020 Telomeric sequences are conserved across species. The most common sequence reported among insects is (TTAGG)n, but its universal occurrence is not a consensus because other canonical motifs have been reported.

Chemical warfare between leafcutter ant symbionts and a co-evolved pathogen
Nature Communications, 2018 Acromyrmex ants cultivate fungus gardens that can be parasitized by Escovopsis sp., leading to colony collapse. Here, Heine et al. identify two secondary metabolites produced by Escovopsis that accumulate in Acromyrmex tissue, reduce behavioural defenses

Putting the waste out: a proposed mechanism for transmission of the mycoparasite Escovopsis between leafcutter ant colonies [PDF]
Royal Society Open Science, 2017 The attine ant system is a remarkable example of symbiosis. An antagonistic partner within this system is the fungal parasite Escovopsis, a genus specific to the fungal gardens of the Attini.
