Fire ant alate virgin and de-alate mated queen brain transcriptomes

ABSTRACT: 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).

DNA methylomes of the fire ant Solenopsis invicta.

Project description:We used whole bodies of four different adult fire ant morphs (alate queens, workers, haploid males, and diploid males) from a single polygyne colony to generate single-base resolution DNA methylation maps. DNA was extracted from whole bodies of individual males, individual queens, and pooled workers. Bisulfite conversion and sequencing was performed by Beijing Genomics Institute (Shenzhen, China). Unmethylated enterobacteria phage lambda DNA (GenBank accession: J02459.1) was added to each genomic DNA sample as a control for bisulfite conversion efficiency.

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.

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).

Comparison of fire ant adult queens with different supergene genotypes (SB/SB and SB/Sb) and different age classes (1-day-old virgins, 11-day-old virgins and reproductive queens) from 2008 and 2009

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 Six-condition experiment: 1-day-old SB/SB virgins, 1-day-old SB/Sb virgins, 11-day-old SB/SB virgins, 11-day-old SB/Sb virgins, SB/SB reproductive queens, SB/Sb reproductive queens. 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.

Comparison of fire ant adult workers with different Gp-9 (BB and Bb) genotypes and from monogyne and polygyne colonies.

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. Keywords: Genotype comparison and social form comparison Three-condition experiment: Gp-9 BB monogyne, Gp-9 BB polygyne, and Gp-9 Bb polygyne. Biological replicates: 8 of each sample type from 2004 compared to common reference RNA batch 2004, and 12 of each sample type from 2006 compared to common reference RNA batch 2006. A fourth condition, Gp-9 bb polygyne with 1 biological replicate from 2004 and 1 from 2006, was compared to the respective reference RNA batch. One replicate per array.
