Research in our lab studies Ecological Evolutionary Developmental Biology (Eco-Evo-Devo), a field of research that integrates concepts such as developmental plasticity, robustness, and endosymbiosis into evolutionary theory. We focus on molecular mechanisms of endosymbiosis by studying bacterial endosymbiosis during early development in ants and true bugs. Endosymbiosis is a rule rather than an exception among multicellular organisms and both micro- and macro-evolutionary events have been shaped by endosymbiotic association, such as hybrid incompatibility and speciation in flies and evolution of eukaryotic cell by symbiogenesis of mitochondria. Molecular mechanisms of endosymbiosis have been treated at the inter-organismal level, our lab explores this phenomenon at the intracellular level during early development in case of endocytic symbionts.


System(s)

Ants of the genus Camponotus, commonly known as carpenter ants, are a hyperdiverse genus of ants with over 1500 species, which harbor the endosymbiotic bacteria Candidatus Blochmania. This bacteria colonizes specialized cells in the host that persist throughout development and adult life and are maternally transmitted to the next generation. Camponotus have acquired endocytic bacteria through a horizontal evolutionary transfer from true bugs by feeding on their honey dew, a nutrient rich substance they excrete. This has led to the evolution of a three-way symbiotic relationship: (1) between true bugs and bacterial endosymbionts, (2) between true bugs and ants, and (3) between ants and bacterial endosymbionts. We exploit this three-way symbiotic relationship to study the ontogeny of the cells and organs that harbour these endosymbionts, the genes that regulate the specification of these cells and the developmental program that mediates these associations in the ant and bug hosts and in the bacterial endosymbionts. By these studies we hope to address questions of developmental integration of endosymbiont within the host, questions of evolutionary origins of endosymbiotic associations, relevance of endosymbiotic associations to organismal biology in general and to ultimately reveal the steps towards the evolution of complexity in higher life forms.


Current Projects

Developmental basis of endosymbiosis: comparative developmental studies

This project involves comparative studies between true bugs and ants and between various ant genera. Bacterial endosymbiosis has independently evolved at least three times within ants in the genera CamponotusFormica and Polyrhachis. One the one hand the bacterial species associated with Camponotus and true bugs have a common origin but on the other hand the ones associated with Formica and Polyrhachis are independently evolved associations. At the same time the endosymbionts have diverged within each lineage together with their hosts. We exploit this phenomenon to study host-symbiont co-evolution and evolutionary divergence and evolutionary convergence of endosymbiosis. In this project we aim to sample carpenter ants and associated true bugs from Turkey and to survey the presence of endosymbionts in these organisms. Based on developmental gene expression and gene function studies, we wish to establish the genetic basis of the establishment of these associations to understand whether conserved, converged or parallel mechanisms exist in these separate lineages. Data from true bugs and our own data in ants suggest that the genes for patterning of the endosymbionts are similar providing a starting point for developmental genetic studies in these diverged lineages.

Human gut microbiome in Turkish populations

There is growing data about association between endosymbionts in the human body that appear to vary between individuals based on their geographical location, their lifestyle, prescription regimes, and most importantly their state of health. We are developing a comprehensive record of microbiome of human gut in Turkey. This database will be used to develop an association map of endosymbionts with disease and healthy state, geographical location, gender, age, and other biometric characteristics. The database aims to be used as a tool to develop microbes unique to Turkish populations for diagnostic and therapeutic purposes.
