Genomic Comparison of the Ants Camponotus floridanus and Harpegnathos saltator
TLDR
The genomes of two socially divergent ant species exhibiting differences in caste development are sequenced and used to compare gene expression and identify differences in epigenetic gene regulation that lead to the phenotypic differences. Expand
Surface hydrocarbons of queen eggs regulate worker reproduction in a social insect.
TLDR
Queen-derived hydrocarbon labels inform workers about the presence of a fertile queen and thereby regulate worker reproduction, which induces workers to refrain from reproducing. Expand
Genome-wide and Caste-Specific DNA Methylomes of the Ants Camponotus floridanus and Harpegnathos saltator
TLDR
These first ant methylomes and their intra- and interspecies comparison reveal an exonic methylation pattern that points to a connection between DNA methylation and splicing, suggesting roles in genome regulation in these social insects. Expand
Are variations in cuticular hydrocarbons of queens and workers a reliable signal of fertility in the ant Harpegnathos saltator?
TLDR
A striking correlation of ovarian activity with CHC variation and its correspondence with the observed recognition behavior exhibited by the workers toward egg-laying nestmates suggests that CHCs serve as a fertility signal in the ant H. saltator, a reliable basis for regulating reproduction. Expand
Phylogenetic and Transcriptomic Analysis of Chemosensory Receptors in a Pair of Divergent Ant Species Reveals Sex-Specific Signatures of Odor Coding
TLDR
This work defines and characterized the major chemoreceptor families in a pair of behaviorally and evolutionarily distinct ant species, Camponotus floridanus and Harpegnathos saltator, and reveals a large number of ant chemoreceptors exhibiting patterns of differential expression and evolution consistent with sex/species-specific functions. Expand
Molecular traces of alternative social organization in a termite genome.
TLDR
The genome and stage-specific transcriptomes of the dampwood termite Zootermopsis nevadensis (Blattodea) are sequence and similarities in the number and expression of genes related to caste determination mechanisms support a hypothesized epigenetic regulation of caste differentiation. Expand
Cuticular hydrocarbons mediate discrimination of reproductives and nonreproductives in the ant Myrmecia gulosa
TLDR
It is suggested that cuticular hydrocarbons function as pheromones allowing for recognition of the queen as well as egg-laying workers. Expand
Cuticular Hydrocarbons Reliably Identify Cheaters and Allow Enforcement of Altruism in a Social Insect
TLDR
In the ant Aphaenogaster cockerelli, it is suggested that even though cheaters would gain from suppressing these profiles, they are prevented from doing so through the mechanisms of hydrocarbon biosynthesis and its relation to reproductive physiology. Expand
Social insect genomes exhibit dramatic evolution in gene composition and regulation while preserving regulatory features linked to sociality.
TLDR
While the "socio-genomes" of ants and the honeybee are broadly characterized by a pervasive pattern of divergence in gene composition and regulation, they preserve lineage-specific regulatory features linked to eusociality, it is proposed that changes in gene regulation played a key role in the origins of insect eussociality. Expand
DNA methylation in social insects: how epigenetics can control behavior and longevity.
TLDR
Recent advances in DNA methylation research are summarized and its significance in understanding of the epigenetic underpinnings of behavior and longevity is discussed. Expand
