Comparative analyses of caste, sex, and developmental stage‐specific transcriptomes in two Temnothorax ants

Abstract: Social insects dominate arthropod communities worldwide due to cooperation and division of labor in their societies. This, however, makes them vulnerable to exploitation by social parasites, such as slave‐making ants. Slave‐making ant workers pillage brood from neighboring nests of related host ant species. After emergence, host workers take over all nonreproductive colony tasks, whereas slavemakers have lost the ability to care for themselves and their offspring. Here, we compared transcriptomes of different … Show more

“…In part, these transcriptomic differences might not only reflect variation in the regulation of fecundity and aging, but simply tissue composition in the gaster of queens and workers with queens exhibiting for example much larger ovaries relative to workers. Previous studies on T. longispinosus contrasting transcriptomes of queens and workers of different fertility status or developmental stages also showed highly divergent gene expression profiles in queens [ 68 , 69 ]. Moreover, queens of T. longispinosus upregulate genes with functions in DNA replication, which is similar to what we find here for T. nylanderi [ 69 ].…”

This is in accordance with comparative work showing that functionalities are conserved in castes of different species [ 70 ].…”

“…If molecules dealing with oxidative stress, or beneficial products of metabolism (nutrient storage proteins) can be spread over the circulatory system, as our results show, certain individuals may bear the costs that others in the network incur. This could account for some of the puzzling results on the plasticity of senescence in social insects ( Kramer et al, 2021 ; Heinze and Giehr, 2021 ; Lucas et al, 2019 ), and provides a new perspective to analyze the regulatory changes of social insect reproductive castes with regard to ageing ( Korb et al, 2021 ; Negroni et al, 2019 ; Elsner et al, 2018 ; Corona et al, 2005 ; Gstöttl et al, 2020 ; Corona et al, 2016 ; von Wyschetzki et al, 2015 ). While most previous work has focused almost exclusively on gene expression, we show that for species that engage in trophallaxis, expression studies are necessary but insufficient to understand where in the colony the relevant genes act.…”

“…If molecules dealing with oxidative stress can be spread over the circulatory system, certain individuals may bear the costs that others in the network incur. This could potentially account for some of the puzzling results of previous studies on senescence in social insects, especially in relation to its apparent plasticity (50)(51)(52), and provides a new perspective to analyze the regulatory changes of social insect reproductive castes with regard to aging (34,(53)(54)(55)(56).…”
