Project description:In the fire ant Solenopsis invicta, a colony queen number is determined by the founding queen's genotypes at the 13 Mb supergene with the non-recombining variants SB and Sb. Single-queen colonies are always headed by SB/SB queens while multiple-queens colonies are always headed by SB/Sb queens. The two variants of the supergene, SB and Sb are completely linked to the two alleles (B and b) of the gene Gp-9. SB/SB and SB/Sb queens differ in many physiological traits including their maturation rate and odor. To explain why SB/SB and SB/Sb queens have different odors, and why SB/SB virgins mature faster and accumulate more fat, we measured expression of ~6000 genes in virgin queens 1 and 11 days after eclosion and in reproductive queens. Keywords: fire ants, Solenopsis invicta, Supergene, queen, Gp-9, social form, maturation, fat storage, queen odor, cuticular hydrocarbon, worker discrimination, monogyne, polygyne, transposon, chemical signaling

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.

Biological replicates: 8 for 1-day-old SB/SB virgins and 1-day-old SB/Sb virgins that were collected in 2008; 8 for 1-day-old SB/SB virgins, 1-day-old SB/Sb virgins that were collected in 2009; 7 for 11-day-old SB/SB virgins and 11-day-old SB/Sb virgins that were collected in 2008; 8 for 11-day-old SB/SB virgins and 11-day-old SB/Sb virgins that were collected in 2009; 8 for SB/SB and SB/Sb reproductive queens (only collected in 2009). Samples were labeled with Cy3 and were compared to the same common reference RNA labeled with Cy5. Samples from 2008 were hybridized on the microarrays batch I and samples from 2009 were hybridized on the microarrays batch J.

Project description:Honeybees are very important eusocial insects and are involved in the pollination of many plants. Queen bees and worker bees develop from the same fertilized eggs, and are thus genetically identical despite their substantial behavioural and physiological differences. The mechanism governing developmental differences between worker and queen bees has always attracted much interest. While there are several reports on mRNA expression related to caste differentiation, no systematic investigation of small RNAs has thus far been carried out. Results: Using deep sequencing we systematically profiled small RNA expression in 4th-6th day worker larvae and queen larvae (the critical stages at which the fates of workers and queens are determined), and found that 38 miRNAs were differentially expressed between worker and queen larvae. In addition, 639 mature miRNA candidates were identified in our work for the first time, of which, 526 were expressed only in workers (318) or queens (208). Conclusion: We present the first profile of honeybee small RNAs and explore the mechanism of caste differentiation between worker and queen bees. Caste-specific expression patterns and large discrepancies in small RNA profiles between worker and queen bees indicate that small RNAs may be related to the differential development of worker and queen bee larvae. Results presented here will make a valuable contribution to understanding the caste switch between worker and queen bees.

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:Female honeybees are specified as workers or queens based on diet during early development. Workers are essentially sterile with a reduced number of ovarioles and no spermatheca. In the presence of the queen (queen mandibular pheromone) and her brood, worker ovaries are kept in an inactive quiescent state. If the queen is removed, or lost, worker bees are able to sense this change in their environment and their ovaries undergo complete remodeling producing unfertilized haploid eggs that will produce male (drone bees). In this study we analyze gene expression in queen, worker, and laying worker ovaries using RNA-seq and explore differences in the chromatin landscape (focusing on H3K27me3).
