Comparative sociogenomics has the potential to provide important insights into how social behaviour evolved. We examined brain gene expression profiles of the primitively eusocial wasp Polistes metricus and compared the results with a growing base of brain gene expression information for the advanced eusocial honeybee, Apis mellifera. We studied four female wasp groups that show variation in foraging/provisioning behaviour and reproductive status, using our newly developed microarray representin ...[more]

Polistes_metricus_dominance_arrays

Project description:This experiment examined brain gene expression differences between females in primitively eusocial Polistes metricus paper wasps. Specifically, we compared expression patterns between groups of females that differed in their reproductive dominance status. We compared dominant and subordinate foundresses, dominant and subordinate workers, and egg-laying queens. The purpose was to investigate how the social environment and dominance status affect brain gene expression in individual females, and to compare these results to previous studies on dominance and aggression on other animals.

Social Regulation of Maternal Traits in Nest-Founding Bumble Bee (Bombus terrestris) Queens

Project description:During the nest-founding phase of the bumble bee colony cycle, queens undergo striking changes in maternal care behavior. Early in the founding phase, prior to the emergence of workers in the nest, queens are reproductive and also provision and feed their offspring. However, later in the founding phase, queens cease feeding offspring and become specialized on reproduction. This transition is synchronized with the emergence of workers in the colony, who assume the task of feeding their siblings. Using a social manipulation experiment, we tested the hypothesis that workers socially regulate the transition from feeding brood to specialization on reproduction in nest-founding bumble bee queens. Consistent with this hypothesis, we found that early-stage queens with workers prematurely added to their nests reduce their brood-feeding behavior and increase egg-laying, and likewise, late-stage queens increase their brood-feeding behavior and decrease egg-laying when workers are removed from their nests. Further, brood-feeding and egg-laying behavior were negatively correlated in these queens. We used an Agilent brain EST-based microarray to explore a second hypothesis, that workers alter brain gene expression in nest-founding queens. We found evidence that brain gene expression in nest-founding queens is altered by the presence of workers, with the effect much stronger in late-stage founding queens. Additionally, expression levels of some genes were correlated with quantitative differences in brood-feeding and egg-laying behavior. This study provides new insights into how the transition from feeding brood to specialization on reproduction in bumble bee queens is regulated during the nest initiation phase of the colony cycle.

The molecular basis and evolution of cooperative brood care in bumblebees

Project description:Sibling care is a hallmark of the social insects, but its evolution remains challenging to explain. The hypothesis that sibling care evolved from ancestral maternal care in the primitively eusocial insects has been elaborated to involve heterochronic changes in gene expression. This elaboration leads to the prediction that workers in these species will show patterns of gene expression more similar to foundress queens, who express maternal care behavior, than to established queens engaged solely in reproductive behavior. We tested this idea in the bumblebee Bombus terrestris using a microarray platform with ca. 4,500 genes. Unlike in the wasp Polistes metricus, in which support for the above prediction has been obtained, we found that patterns of brain gene expression in foundress and queen bumblebees were more similar to each other than to workers. However, comparisons of lists of differentially expressed genes derived from this study and gene lists from microarray studies in Polistes and the honeybee Apis mellifera suggest that there is a shared set of genes involved in the regulation of related social behaviors across independent eusocial lineages. Together, these results suggest that the multiple independent evolutions of eusociality in the insects involved a combination of shared and different mechanisms.

Genomics of colony founding in fire ants - pleo2

Project description:This experiment was performed to investigate the effect of the manipulation of social rank on gene expression. Fire ants newly mated queens were paired and placed in nesting chambers. After emergence of workers, queensM-^R behavior was monitored. Once the behavioral observation revealed the social rank of the two cofoundresses (winners and losers), queens were weighed again and re-paired with a different partner. We created the following three groups of queens: a) winner + winner (similar weight), b) loser + loser (similar weight), and c) winner + loser (different weights). Again, we monitored the behavior until the social rank of the newly coupled specimens was evident and we collected 4 new behavioral phenotypes in the same way as above: a) winners switched into losers (win/los), b) losers switched into winners (los/win), c) continuing winners (win/win) and d) continuing losers (los/los).

Timecourse of gene expression after oprhaning of virgin Solenopsis invicta fire ant queens

Project description:In species with social hierarchies, the death of dominant individuals typically upheaves the social hierarchy and provides an opportunity for subordinate individuals to become reproductives. Such a phenomenon occurs in the monogyne form of the fire ant, Solenopsis invicta, where colonies typically contain a single wingless reproductive queen, thousands of workers and hundreds of winged non-reproductive virgin queens. Upon the death of the mother queen, many virgin queens shed their wings and initiate reproductive development instead of departing on a mating flight. Workers progressively execute almost all of them over the following weeks. To identify the molecular changes that occur in virgin queens as they perceive the loss of their mother queen and begin to compete for reproductive dominance, we collected virgin queens before the loss of their mother queen, six hours after orphaning and 24 hours after orphaning. Their RNA was extracted and hybridized against microarrays to examine the expression levels of approximately 10,000 genes. We identified 297 genes that were consistently differentially expressed after orphaning. These include genes that are putatively involved in the signaling and onset of reproductive development, as well as genes underlying major physiological changes in the young queens. 3 samples: 0h, 6h, 24; five queens pooled per samples; each replicate loop of 3 samples was taken from an independent colony; 8 biological replicates (colonies) used. Hybridization according to a Dye-balanced loop design (no technical replication)

Caste-specific expression patterns of olfactory related genes in the leaf-cutting ant, Atta vollenweideri

Project description:To allow estimation of the complexity and gene expression differences of the antennal transcriptome between sexes as well as between castes, microarrays were designed based on an assembly of A. vollenweideri antennal sequence data from all sexes and castes. The microarrays were hybridized with samples generated from the respecitve antennal tissues, with four independent sample pools per sex and caste. Custom 2x105 k Agilent microarrays (Agilent Technologies, Palo Alto, CA) were designed based on the antennal transcriptome data of A.vollenweideri. For all contigs with an identified ORF by automatic annotation, two 60mer oligo probes were designed, with two additional 60mer oligo probes for opposite reading direction for those with unknown ORF, thus resulting in 4 oligo probes per contig. Additionally, we added three 60mer oligo probes for each identified and revised OR coding gene, resulting in a total of 5 oligo probes per OR coding contig. For design and arrangement of the Agilent microarrays, the eArray software (Agilent Technologies, Palo Alto, CA) was used. For sex- and caste-specific antennal microarray hybridizations, RNA from antennae of 50 (Males) to 300 (Tiny Workers) individuals was pooled per preparation, and four pools (replicates) each were dissected per sex and caste, respectively. Double purified total RNA was added to Agilent Technologies spike-in RNA and labeld using QuickAmp Amplification kit (Agilent Technologies) and the Kreatech ULS Fluorescent Labeling Kit with cyanine 3-CTP dye following the manufacturerÂ´s instructions. Amplified cRNA samples were used for microarray hybridization, scanned with the Agilent Microarray Scanner and data was extracted from TIFF images with Agilent Feature Extraction software version 9.1. Raw data output files were analyzed using the GeneSpring GX11 and GeneSifter microarray analysis softwares.

Transcription profiling of honeey bee to assess the effects of mating and instrumental insemination on honey bee behavior physiology and brain gene expression

Project description:Mating is fundamental to the success and reproduction of most organisms, although the physiological and transcriptional changes associated with this process have been largely characterized only in Drosophila. In this study, we use honey bees as a model system since their queens undergo massive and permanent physiological and behavioral changes following mating. Previous studies have identified changes associated with the transition from a virgin queen to a fully-mated, egg-laying queen. Here, we further uncouple the mating process to examine the effects of natural mating vs. instrumental insemination and saline vs. semen insemination. We observed significant overlap between our study and analogous studies in Drosophila, suggesting that some post-mating mechanisms are conserved across insect orders.
