Epigenetic changes and an extensive rewiring of the transcriptome underlie worker size distribution in the Florida carpenter ant [RNA-seq]

Project description:Variation in continuous traits, such as height, is a complex output of genetic and environmental factors. In the Florida carpenter ant, workers are 75% genetically related but exhibit a wide range of lengths that broadly categorizes them into minor or major subcastes with specific roles within the colony. While initial studies have suggested that epigenetic changes can mediate the influence of the environment in the differential development of minor and major ants, no study has comprehensively studied ant size as a continuous phenotype with genome-wide approaches. Here, we exploit the entire continuous spectrum of ant size, mRNA expression, microRNA expression, and DNA methylation – in combination with genomic sequencing – to identify the molecular and epigenetic factors driving the determination of body size. We report dramatic changes in gene expression in key genes linked to sugar metabolism as well as the correlation of expression of a large proportion of the transcriptome to size, involving pathways related to DNA replication, muscle growth, and neuronal development. We further identify and investigate the correlation of the expression of microRNAs and levels of DNA methylation with size, as well as their link to histone modifications, which together, might sculpt differential gene expression profiles. Together, this study unveils a coordinated molecular and epigenetic regulatory network determining body size, offering valuable insights into developmental biology and the molecular contributions to body size in the context of C. floridanus and beyond.

Size and shape in the evolution of ant worker morphology.

Project description:Morphological evolution in ants has been traditionally thought as being strongly influenced by selection for colony ergonomic efficiency. Although many studies have focused on the evolution of social characteristics in ants, little is known about the evolution of worker morphology at a macroevolutionary scale. In this study, we investigate the tempo and mode of the evolution of worker morphology, focusing on changes in size and shape. Our datasets included a large sample of species from different ant genera, as well as variation within the hyperdiverse genus Pheidole, for a total of 1650 measurements. The rate of size evolution was at least five times faster than the rate of shape evolution. The fit of alternative models of morphological evolution indicated statistically significant phylogenetic signal in both size and shape and in all datasets. Finally, tests of rate heterogeneity in phenotypic evolution among lineages identified several shifts in rates of evolution in both datasets, although the timing of shifts in size and shape was usually not concordant.
