Credit: HHU \/ Christoph Kawan<\/figcaption><\/figure>\n<p>Behavioural interactions between organisms are fundamental and often inherited. Every human being and every animal interacts with other individuals in its social group in one way or another through its behaviour. In the animal kingdom, this has considerable advantages in collective foraging for food, defence against predators and the rearing of offspring.<\/p>\n<p>In some animals, such as honeybees, the social behaviour bonds are so strong that the individual members form a tight-knit society that function collectively as a single \u201csuperorganism\u201d. Through their individual behaviour, thousands of worker bees protect the entire colony, feed it and care for the brood.<\/p>\n<p>Professor Dr Martin Beye, who heads the Institute of Evolutionary Genetics at HHU and is the corresponding author of the study that has now been published in Science Advances, emphasises: \u201cThe behavioural repertoire of the individual bees and their function in the colony are not learned, but rather inherited. Until now, it was not known how such complex behaviours were genetically encoded.\u201d<\/p>\n<p>Together with colleagues from the universities in Frankfurt\/Main, Oxford and W\u00fcrzburg, the team of researchers at HHU led by Beye and first author Dr Vivien Sommer has now discovered that a special gene known as\u00a0<em>dsx\u00a0<\/em>specifies worker bee-specific behaviour.<\/p>\n<p>Sommer: \u201cThe gene programmes whether a worker bee takes up a task in the colony and for how long. This includes collective tasks such as caring for the larvae or foraging for food and social exchanges on food sources, for example.\u201d<\/p>\n<p>The biologists used the CRISPR\/Cas9 genetic scissors in their investigations to modify or switch off the\u00a0<em>dsx\u00a0<\/em>gene in selected bees. They attached a QR code to the manipulated bees, then monitored their behaviour in the hive with cameras.<\/p>\n<p>The resulting video sequences were analysed with the support of artificial intelligence to determine the bees\u2019 individual behavioural patterns.<\/p>\n<p>Sommer: \u201cOur central question was whether and how the inherited behavioural patterns changed as a result of the gene modification. Such changes must be reflected in the nervous system of the worker bees where the specific behaviour is controlled.\u201d<\/p>\n<p>The researchers introduced green fluorescent protein (GFP) into the\u00a0<em>dsx\u00a0<\/em>sequence so that GFP was produced together with the dsx protein. The neuronal circuits could then be viewed using fluorescence microscopy, in both the unmodified bees and in those with genetic modifications.<\/p>\n<p>\u201cWe were able to use these tools to see exactly which neural pathways the\u00a0<em>dsx\u00a0<\/em>gene creates in the brain and how this gene in turn specifies the inherited behavioural patterns of honeybees,\u201d explains doctoral researcher Jana Seiler, who is also a co-author of the study.<\/p>\n<p>\u201cOur findings indicate a fundamental genetic programme that determines the neuronal circuitry and behaviour of worker bees,\u201d says Professor Dr Wolfgang R\u00f6ssler from the Department of Behavioural Physiology and Sociobiology, who led the study at the University of W\u00fcrzburg.<\/p>\n<p>In the next step, the researchers now want to move from the level of the individual honeybee to the bee colony superorganism.<\/p>\n<p>Alina Sturm, who is also a doctoral researcher at HHU and study co-author, adds: \u201cWe hope to find the link between individual programming and the coordinated behaviour of many individuals.\u201d<\/p>\n<h2 class=\"wp-block-heading\">About this genetics and behavioral neuroscience research news<\/h2>\n<p class=\"has-background\" style=\"background-color:#ffffe8\"><strong>Author: <\/strong><a href=\"http:\/\/neurosciencenews.com\/cdn-cgi\/l\/email-protection#3c5d4e5259125f505d494f4f59527c545449125859\" target=\"_blank\" rel=\"noreferrer noopener\">Arne Claussen<\/a><br \/><strong>Source: <\/strong><a href=\"https:\/\/hhu.de\" target=\"_blank\" rel=\"noreferrer noopener\">HHU<\/a><br \/><strong>Contact: <\/strong>Arne Claussen \u2013 HHU<br \/><strong>Image: <\/strong>The image is credited to HHU \/ Christoph Kawan<\/p>\n<p class=\"has-background\" style=\"background-color:#ffffe8\"><strong>Original Research: <\/strong>Open access.<br \/>\u201c<a href=\"https:\/\/www.science.org\/doi\/10.1126\/sciadv.adp3953\" target=\"_blank\" rel=\"noreferrer noopener\">Dedicated developmental programing for group-supporting behaviors in eusocial honeybees<\/a>\u201d by Martin Beye et al. <em>Science Advances<\/em><\/p>\n<hr class=\"wp-block-separator has-text-color has-pale-cyan-blue-color has-alpha-channel-opacity has-pale-cyan-blue-background-color has-background\"\/>\n<p><strong>Abstract<\/strong><\/p>\n<p><strong>Dedicated developmental programing for group-supporting behaviors in eusocial honeybees<\/strong><\/p>\n<p>The evolutionary changes from solitary to eusocial living in vertebrates and invertebrates are associated with the diversification of social interactions and the development of queen and worker castes.<\/p>\n<p>Despite strong innate patterns, our understanding of the mechanisms manifesting these sophisticated behaviors is still rudimentary.<\/p>\n<p>Here, we show that\u00a0<em>doublesex<\/em>\u00a0(<em>dsx<\/em>) manifests group-supporting behaviors in the honeybee (<em>Apis mellifera<\/em>) worker caste.<\/p>\n<p>Computer-based individual behavioral tracking of worker bees with biallelic stop mutations in colonies revealed that the\u00a0<em>dsx<\/em>\u00a0gene is required for the rate and duration of group-supporting behavior that scales the relationship between bees and their work.
