Comparative physical mapping of 18S rDNA in the karyotypes of six leafcutter ant species of the genera Atta and Acromyrmex (Formicidae: Myrmicinae)
Leafcutter ants of the Atta and Acromyrmex genera are important plagues in different cultures. Cytogenetic data on chromosome number, morphology, and chromosomal banding pattern are only available for 17 species of leafcutter ants.

| description | Leafcutter ants of the
Atta
and
Acromyrmex
genera are important plagues in different cultures. Cytogenetic data on chromosome number, morphology, and chromosomal banding pattern are only available for 17 species of leafcutter ants. Molecular cytogenetic data for the detection of ribosomal genes by the FISH technique are scarce, and only 15 Neotropical ant species have been studied. This study aimed to physically map the 18S ribosomal RNA genes (rDNA) of six leafcutter ants belonging to the genera
Atta
and
Acromyrmex
using FISH. The results were compared with data on the fluorochrome CMA
3
currently available for these species. All analyzed species presented the 18S rDNA on one pair of chromosomes. In
Acromyrmex subterraneus molestans
and
Ac. aspersus
, FISH signals were observed in the terminal region of the short arm of the largest subtelocentric pair, while in
Atta bisphaerica, A. laevigata
, and
A. sexdens
, FISH signals were observed in the interstitial region of the long arm of the fourth metacentric pair. In
Acromyrmex striatus
, 18S rDNA was located in the interstitial region of the second metacentric pair. The karyotypic formula for
Ac. aspersus
was 2n = 38 (8m + 10sm + 16st + 4a), representing the first report in this species. The observed 18S rDNA regions in
A. laevigata, A. sexdens, A. bisphaerica, Ac. aspersus
, and
Ac. subterraneus molestans
corresponded to the CMA
3
+
bands, while in
Ac. striatus
, several GC-rich bands and one pair of 18S rDNA bands were observed. No differential bands were visible using the DAPI fluorochrome. Karyotype uniformity with previously studied
Atta
spp. was also observed at the level of molecular cytogenetics using 18S rDNA FISH. A difference in the size of the chromosomal pair carrying the 18S rDNA gene was observed in
Ac. striatus
(2n = 22) and
Atta
spp. (2n = 22) highlighting the dissimilarity between these species. The results from the present study contribute to the description of 18S rDNA clusters in Neotropical ants. |
