Effect of Wolbachia Infection on Aging and Longevity-Associated Genes in Drosophila [chapter]

Oleksandr M. Maistrenko, Svitlana V. Serga, Alexander M. Vaiserman, Iryna A. Kozeretska
2015 Life Extension  
Microbiota is known to interact with metabolic and regulatory networks of the host affecting its fitness. The composition of microbiota was shown to change throughout the host aging. Such changes can be likely caused by aging process or, vice versa, changes in microbiota composition can impact the aging process. It is suggested that microbiota plays an important role in life span determination. Several species from the genus Drosophila, especially D. melanogaster, are powerful models to study

The host fitness can be substantially affected by endosymbiotic bacteria such as Wolbachia that infects up to two-thirds of insects taxa, including Drosophila. Wolbachia was shown to significantly affect Drosophila aging and life span. However, the molecular mechanisms underlying interactions between Wolbachia and Drosophila remain mostly unknown. In this chapter, we summarize data suggesting that Wolbachia-Drosophila molecular cross-talk associated with life span determination and aging can occur through the immune deficiency pathway, stress-induced JNK pathway, insulin/IGF signaling pathway, ecdysteroid biosynthesis and signaling pathway, as well as through the heat shock and autophagy-specific genes/proteins.

Colonization of a temperate-zone region by the fruit fly Drosophila simulans (Diptera: Drosophilidae)

Svitlana V. Serga, Oleksandr M. Maistrenko, Andrii I. Rozhok, Timothy A. Mousseau, Iryna A. Kozeretska
2015 Canadian Journal of Zoology  
Drosophila simulans Sturtevant, 1919 and Drosophila melanogaster Meigen, 1830 are sibling species that occupy similar niches. However, unlike D. simulans, D. melanogaster has spread far beyond tropical and subtropical regions deep into temperate climate zones. A number of invasion events by D. simulans into temperate climate zones have been reported, however its ability to overwinter and establish local populations in these areas is disputed. Here we report the wide dispersal of D. simulans in

D. simulans flies found in Ukraine belong to the siII mtDNA haplogroup and are infected with maternally inherited intracellular symbiotic bacteria of the genus Wolbachia sp. of the strain wRi. These genetic markers indicate a common origin of the Ukrainian D. simulans flies from a subgroup of the species found to invade other temperate climate areas worldwide. Here, we report for the first time detection of D. simulans flies early in the breeding season in a temperate climate area with severe winter conditions. We also report a moderate negative relationship between D. simulans relative abundance and average temperature in the month of sampling reflecting this species' known lower tolerance of high temperatures.
