Project description:Transcriptomes of dissected brains from alate virgin and de-alate mated queens from polygyne fire ants were analyzed and compared. Four replicates of each condition were obtained. Thirteen genes were upregulated in mated queen brain and nine were downregulated. We found that for four differentially expressed genes in brain selected for qPCR analyses, changes in gene expression were most likely driven by the changes in physiological state (i.e. age, nutritional status or dominance rank) or in social environment (released from influence of primer pheromone).

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).

Project description:The goal of this study was to assay the extent of variation in chromatin organization between 3 ant castes (major and minor female workers and males) in one colony of Camponotus floridanus carpenter ant using ChIPseq. 45 samples total: 30 ChIP samples and 3 inputs for total histone H3, 7 histone H3 PTMs and RNA Pol II in major, minor, and male ants; CBP in major and minor ants; the major H3K27ac sample was replicated. 4 ChIP samples for H3 and H3K27ac in brains of majors and minors, and 2 inputs. 2 RNAseq samples for major and minor ants head+thorax; 4 RNAseq samples for brain (majors and minors with 2 replicates each).

Project description:Social plasticity is a pervasive feature of animal behavior. Animals adjust the expression of their social behavior to the daily changes in social life and to transitions between life-history stages, and the ability to change in these ways impacts their Darwinian fitness. This behavioral plasticity may be achieved either by rewiring or by biochemically switching nodes of the neural network underlying the social behavior in response to perceived social information. Independent of the proximate mechanisms, at the neuromolecular level social plasticity relies on the regulation of gene expression, such that different neurogenomic states emerge in response to different social stimuli and the switches between states are orchestrated by signaling pathways that interface the social environment and the genotype. Here, we test this hypothesis by characterizing the changes in the brain profile of gene expression in response to social odors in the Mozambique Tilapia, Oreochromis mossambicus. This species has a rich repertoire of social behaviors during which both visual and chemical information are conveyed to conspecifics. Specifically, dominant males increase their urination frequency during agonist encounters and during courtship to convey chemical information reflecting their dominance status. We recorded electro-olfactograms to test the extent to which the olfactory epithelium can discriminate between olfactory information from dominant and subordinate males as well as from pre- and post-spawning females. We then performed a genome-scale gene expression analysis of the olfactory bulb and the olfactory cortex homolog in order to identify the neuromolecular systems involved in processing these social stimuli. Our results show that different olfactory stimuli from conspecificsM-bM-^@M-^Y have a major impact in the brain transcriptome, with different chemical social cues eliciting specific patterns of gene expression in the brain. These results confirm the role of rapid changes in gene expression in the brain as a genomic mechanism underlying behavioural plasticity and reinforce the idea of an extensive transcriptional plasticity of cichlid genomes, especially in response to rapid changes in their social environment. Brain samples from 40 African cichlid males, Oreochromis mossambicus were collected after stimulation with different social olfactory stimuli. Samples were collected from 2 brain areas: BO and Dp after males were exposed to dominant (DOM) and subordinate (SUB) male urine and pre- (PRE) and post-ovulatory (POST) female scent. In OB 5 replicates were collected from males exposed to DOM and 6 to the other stimuli. For Dp 5 replicates were collected from males exposed to DOM and POST, 4 to SUB and 6 to PRE.

Project description:Hemizygous ato[1]/Df(3R)p[13] null mutants lack Johnston organ (JO) in their 2nd antennal segment. We screened for genes that are expressed in JO by comparing the 2nd antennal segment transcriptomes between ato[1]/Df(3R)p[13] mutants and balanced Df(3R)p[13]/TM3 and ato[1]/TM3 controls. To assess transcriptomes, we isolated the 2nd antennal segments of ~50 flies per strain and extracted their total RNA. Because about half of the JO cells are sensory neurons, we also isolated RNA from the brains of ato[1]/TM3 controls to delineate neuronal JO genes. cRNA was hybridized to Affymetrix Drosophila Genome 2.0 arrays. For each experiment, three biological replicates were run.

Project description:In fire ants, a complex colony level phenotype, colony queen number, is completely associated with a single Mendelian factor marked by the gene Gp-9. The first aim of this study was to investigate whether variation in the genomic region marked by Gp-9 is associated with differences in patterns of expression of genes other than Gp-9 in workers. The second aim was to study how the social environment (i.e., presence or absence of nestmate workers with the b allele) can alter individual gene expression patterns.

Project description:Animal longevity widely differs across species, and even individuals from the same species may exhibit different rates of ageing. In different species, the rate at which individuals actually age is related to the level of their social interactions, but this was still not known in ants. In a given colony, ant individuals are close genetic relatives, exhibit very different behaviours and a contrasted lifespan according to the Caste. Such characteristics constitute main advantages to study relationships between sociality and ageing. Therefore, the aim of this study was to characterize differences in the proteome of Lasius niger queens versus that of domestic and foraging workers. Proteomic data were put in relation with the behaviour of individuals from the three Castes. Hence, it was found that sociality correlates with ant longevity, with i) social immunity enabling the queen to mainly invest in soma protection, and ii) marked exposition of workers to the environment and nutrients inducing metabolic pathways that reduce their lifespan.
