Project description:Investigation of whole genome gene expression level changes of testes in the meiotic drive system in aedes aegypti during spermatogenesis compared to non drive strain. The meiotic drive system in Aedes aegypti causes the female determining chromosome to fragment during spermatogenesis. A six chip study using total RNA from three separately extracted non driving strain testes of Aedes aegypti and three separately extracted meiotic drive strain testes of Aedes aegypti.

Project description:We conducted a whole transcriptome analysis of testes from a meiotic drive-carrying strain (T37) in comparison with a drive-sensitive strain (RED) using microarrays based on the complete annotated Ae. aegypti gene set. The T37 strain, which carries a strong meiotic drive gene (Mori et al., 2004 (PMID 15605641)), was established from mosquitoes collected in Trinidad. The RED strain is highly sensitive to the meiotic drive gene (Hickey and Craig, 1966 (PMID ); Mori et al., 2004 (PMID 15605641)). A six-chip study using total RNA recovered from three biological samples of the T37 strain and another three biological samples of the Red strain of Aedes aegypti. Each chip measures the expression level of 16,092 genes annotated from the Aedes aegypti genome sequence, with twenty 60-mer probe pairs (PM/MM) per gene, with three-fold technical redundancy.

Project description:Female Aedes aegypti mosquitoes impose a severe global public health burden as primary vectors of multiple viral and parasitic pathogens. Under optimal environmental conditions, Aedes aegypti females have access to human hosts that provide blood proteins for egg development, conspecific males that provide sperm for fertilization, and freshwater that serves as an egg-laying substrate suitable for offspring survival. As global temperatures rise, Aedes aegypti females are faced with climate challenges, like intense droughts and intermittent precipitation, which create unpredictable and suboptimal conditions for the egg-laying step of their reproductive cycle. Aedes aegypti mosquitoes nonetheless show remarkable reproductive resilience, but how they achieve this is unknown. Here we show that under drought-like conditions simulated in the laboratory, mated, blood-fed Aedes aegypti females carrying mature eggs retain them in their ovaries for extended periods, while maintaining the viability of these eggs until they can be deposited in freshwater. Using transcriptomic and proteomic profiling of Aedes aegypti ovaries, we identify two previously uncharacterized genes – here named tweedledee and tweedledum – that show ovary-enriched, temporally-restricted expression during egg retention. These genes are mosquito-specific, linked within a syntenic locus, and rapidly evolving under positive selection, raising the possibility that they serve an adaptive function. Using loss-of-function mutagenesis to disrupt both genes, we show that, tweedledee and tweedledum, which encode secreted proteins, are specifically required for extended retention of viable eggs, such as during intermittent precipitation or drought. These results highlight an elegant example of taxon-restricted genes at the heart of an important adaptation that equips Aedes aegypti females with “insurance” to, when contextually appropriate, flexibly extend their reproductive sequence without losing reproductive capacity, thus allowing this species to exploit diverse and unpredictable habitats.
