Early Behavioral and Molecular Events Leading to Caste Switching in the Ant Harpegnathos
Downloaded from genesdev.cshlp.org on September 25, 2021 - Published by Cold Spring Harbor Laboratory Press Early behavioral and molecular events leading to caste switching in the ant Harpegnathos Comzit Opachaloemphan,1,5 Giacomo Mancini,2,5 Nikos Konstantinides,2,5 Apurva Parikh,2 Jakub Mlejnek,2 Hua Yan,1,3,4 Danny Reinberg,1,3,6 and Claude Desplan2,6 1Department of Biochemistry and Molecular Pharmacology, New York University School of Medicine, New York, New York 10016, USA; 2Department of Biology, New York University, New York, New York 10003, USA; 3Howard Hughes Medical Institute, New York University School of Medicine, New York, New York 10016, USA Ant societies show a division of labor in which a queen is in charge of reproduction while nonreproductive workers maintain the colony. In Harpegnathos saltator, workers retain reproductive ability, inhibited by the queen phero- mones. Following the queen loss, the colony undergoes social unrest with an antennal dueling tournament. Most workers quickly abandon the tournament while a few workers continue the dueling for months and become gamergates (pseudoqueens). However, the temporal dynamics of the social behavior and molecular mechanisms underlining the caste transition and social dominance remain unclear. By tracking behaviors, we show that the gamergate fate is accurately determined 3 d after initiation of the tournament. To identify genetic factors responsible for this commitment, we compared transcriptomes of different tissues between dueling and nondueling workers. We found that juvenile hormone is globally repressed, whereas ecdysone biosynthesis in the ovary is increased in gamergates. We show that molecular changes in the brain serve as earliest caste predictors compared with other tissues.

This is due to a variety of features: highly cooperative behavior performed by colony members and their specialization on a variety of tasks. Diverse physiological and behavioral specializations are regulated not only by the genetic system, but also by the epige- netic system which alters gene expressions without modifying the genetic code. This review will summarize recent advancements in such studies in eusocial insects. Abstract: Eusocial insects, such as bees, ants, and wasps of the Hymenoptera and termites of the Blattodea, are able to generate remarkable diversity in morphology and behavior despite being genetically uniform within a colony. Most eusocial insect species display caste structures in which reproductive ability is possessed by a single or a few queens while all other colony members act Citation: Sieber, K.R.; Dorman, T.; as workers. However, in some species, caste structure is somewhat plastic, and individuals may Newell, N.; Yan, H.

Social Stress Increases the Susceptibility to Infection in the Ant Harpegnathos Saltator Received: 19 February 2016 Sebastian A
www.nature.com/scientificreports OPEN Social stress increases the susceptibility to infection in the ant Harpegnathos saltator Received: 19 February 2016 Sebastian A. Schneider1, Charlotte Scharffetter2, Anika E. Wagner2, Christine Boesch2, Accepted: 18 April 2016 Iris Bruchhaus3, Gerald Rimbach2 & Thomas Roeder1,4 Published: 10 May 2016 Aggressive interactions between members of a social group represent an important source of social stress with all its negative follow-ups. We used the ponerine ant Harpegnathos saltator to study the effects of frequent aggressive interactions on the resistance to different stressors. In these ants, removal or death of reproducing animals results in a period of social instability within the colony that is characterized by frequent ritualized aggressive interactions leading to the establishment of a new dominance structure. Animals are more susceptible to infections during this period, whereas their resistance against other stressors remained unchanged. This is associated with a shift from glutathione- S-transferase activities towards glutathione peroxidase activities, which increases the antioxidative capacity at the expense of their immune competence. Stress is usually defined as an alteration that perturbs organismic homeostasis. In order to re-establish a home- ostatic equilibrium, organisms are able to launch stress responses1,2. Strong and prolonged confrontation with stressors is believed to be negatively correlated with the immune system’s performance and therewith with the resistance towards infections3,4. Although the existence of this relationship between stress and immunity is com- monly accepted, the underlying molecular mechanisms are not fully understood5,6. Stress can be physical or behavioural in nature. Behaviourally induced stress results from interactions with conspecifics and individuals from other species, primarily with potential predators and with prey.

Molecular Pharmacology and Toxinology of Venom from Ants
Chapter 8 Molecular Pharmacology and Toxinology of Venom from Ants A.F.C. Torres, Y.P. Quinet, A. Havt, G. Rádis-Baptista and A.M.C. Martins Additional information is available at the end of the chapter http://dx.doi.org/10.5772/53539 1. Introduction In the last decades, poisonous animals have gained notoriety since their venoms (secreted or injected) contain several of potentially useful bioactive substances (polypeptide toxins), which are mostly codified by a single gene or, in the case of venom organic compounds, by a given enzymatic route presented in a specialized tissue where the biosynthesis occur – the venom gland. In this context, in the age of genomic sciences, sequencing the entire genome or portion of it, can be thought as the straightforward step to understand a given venom composition. Particularly because, in many cases, the venom is produced in so small quantities, requiring great challenge (natural and bureaucratic) to obtain biological material for its investigation or the necessity of sacrifice the animal to get samples for analysis by conventional biochemical methods. Genome sequencing allows us the identification of mRNAs, as well as prediction of protein structure and function. In addition, the construction of cDNA libraries is useful to clone, catalog and identify genes, and subsequently express the proteins of interest from these libraries. By this approach, we can have adequate amounts of polypeptide toxins for functional analysis and application, by which otherwise would be difficult to isolate. According to [1], venoms’ complexity in terms of peptide and protein contents, together with the number of venomous species indicate that only a small proportion (less than 1%) of the all bioactive molecules has been identified and characterized to date, and little is known about the genomic background of the venomous organisms.
