Atta cephalotes Assembly and Gene Annotation
About Atta cephalotes
Leaf-cutter ants, such as Atta cephalotes, are among the most important herbivorous insects in the neotropics. These ants harvest vast quantities of fresh leaf material, which is used to cultivate a fungus that serves as the colony's primary food source. This obligate ant-fungus mutualism is one of the few occurrences of farming by non-humans and likely enabled the formation of their massive colonies. Leaf-cutter ant colonies display one of the most complex polymorphic caste systems, with workers ranging from small garden workers to large soldiers.

The genome of Atta cephalotes was assembled (to a coverage depth of ~18-20x) using genomic DNA from an alate male ant, collected from a mature colony in Panama. The sequencing was performed with 454 Titanium technology, allied with shotgun 8-kbp and 20-kbp paired-end sequencing datasets . Ensembl Metazoa contains the Attacep1.0(2) version of the assembly, which adds the mitochondrial chromosome to the Attacep1.0 version.
The annotations displayed in Ensembl Metazoa are the NCBI Atta cephalotes Annotation Release 100 set. This set is based on the Official Gene Set v1.2, from the Ant Genomes Portal ; that original gene set is available as a separate track in the genome browser.
