Ectodini cichlid brain comparison of mating type

ABSTRACT: Throughout the animal kingdom, we know many examples of mating system evolution that exemplify adaptive responses to changes in the environment, yet our understanding of the accompanying neural and molecular mechanisms that give rise to such behavioral changes remains understudied. In the present study we aimed to define the molecular basis of interspecific variation in social organization in Ectodini cichlids from Lake Tanganyika. We selected four closely related species that represent two independent evolutions of monogamy: the polygynous Xenotilapia ochrogenys, the monogamous Xenotilapia flavipinnis, the polygynous Microdontochromis tenuidentata and the monogamous Asprotilapia leptura. Using a single cichlid microarray platform, we conducted a total of 28 direct comparisons for neural gene expression level among males and 26 among females of four species that represent 2 independent evolutions of monogamy. Our results indicate the gene expression profiles display remarkable plasticity across different time scales because we find differences associated with sex, mating system, and lineage.

Conserved Transcriptomic Profiles Underpin Monogamy across Vertebrates

Project description:We compare fore- and mid-brain transcriptomes of reproductive males in monogamous and non-monogamous species pairs of Peromyscus mice, Microtus voles, parid songbirds, dendrobatid frogs, and Xenotilapia species of cichlid fishes. Our study provides evidence of a universal transcriptomic mechanism underlying the evolution of monogamy in vertebrates.

Dynamic co-evolution of transposable elements and the piRNA pathway in East African cichlid fishes

Project description:East African cichlid fishes have radiated in an explosive fashion. The (epi)genetic basis for the abundant phenotypic diversity of these fishes remains largely unknown. As transposable elements (TEs) contribute extensively to genome evolution, we reasoned that TEs may have fuelled cichlid radiations. While TE-derived genetic and epigenetic variability has been associated with phenotypic traits, TE expression and epigenetic silencing remain unexplored in cichlids. Here, we profiled TE expression in African cichlids, and describe dynamic expression patterns during embryogenesis and according to sex. Most TE silencing factors are conserved and expressed in cichlids. We describe an expansion of two truncated Piwil1 genes in Lake Malawi/Nyasa cichlids, encoding a Piwi domain with catalytic potential. To further dissect epigenetic silencing of TEs, we focused on small RNA-driven epigenetic silencing. We detect a small RNA population in gonads consistent with an active Piwi-interacting RNA (piRNA) pathway targeting TEs. We uncover fluid genomic origins of piRNAs in closely related cichlid species. This, along with signatures of positive selection in piRNA pathway factors, points towards fast co-evolution of TEs and the piRNA pathway. Our study is the first step to understand the contribution of ongoing TE-host arms races to the cichlid radiations in Africa.

Dynamic co-evolution of transposable elements and the piRNA pathway in East African cichlid fishes

Project description:East African cichlid fishes have diversified in an explosive fashion, but the (epi)genetic basis of the phenotypic diversity of these fishes remains largely unknown. Although transposable elements (TEs) have been associated with phenotypic variation in cichlids, little is known about their transcriptional activity and epigenetic silencing. Here, we describe dynamic patterns of TE expression in African cichlid gonads and during early development. Orthology inference revealed an expansion of piwil1 genes in Lake Malawi cichlids, likely driven by PiggyBac TEs. The expanded piwil1 copies have signatures of positive selection and retain amino acid residues essential for catalytic activity. Furthermore, the gonads of African cichlids express a Piwi-interacting RNA (piRNA) pathway that target TEs. We define the genomic sites of piRNA production in African cichlids and find divergence in closely related species, in line with fast evolution of piRNA-producing loci. Our findings suggest dynamic co-evolution of TEs and host silencing pathways in the African cichlid radiations. We propose that this co-evolution has contributed to cichlid genomic diversity.

Project description:This study examines genomic copy-number variation among African cichlids spanning multiple tribes and radiations. We map CNVs and hotspots throughout the Oreochromis niloticus reference genome, categorize gene ontology enrichment within CNV regions, and compare results with sequence-based cichlid phylogenies.

Post-mating expression of female D. melanogaster genomes experimentally evolved under different post-copulatory sexual selection regimes

Project description:By combining an experimental evolution approach with genomic techniques, we investigated the effects of seminal fluid on female gene expression. In our study, we experimentally manipulated the mating system in replicate populations of D. melanogaster, by removing post-copulatory sexual selection, with the aim of testing differences in short term post-mating reaction of females evolved under different mating strategies. We show that monogamous females suffer decreased fecundity, regardless of the type of male they were mated with, and that their post-mating gene expression profiles differ significantly from promiscuous females, involving 1141 transcripts (9% of the genes tested). These transcripts are active in several tissues, mainly ovaries, neural tissues, midgut and spermathecae, and are involved in metabolic processes, reproduction and signaling pathways. Our results provide a list of candidate genes responsible for the decrease in female fecundity in the absence of post-copulatory sexual selection, and demonstrate how the female post-mating response can evolve under different mating systems over relatively short time frames. From a LHM base population, we created 8 replicate populations and maintained them under experimental evolution: 4 populations were allowed to mate only once every generation (monogamy), and the other 4 were kept under the standard mating protocol (promiscuous). After 46 generation, we crossed males and females within the same population and with individuals of the opposite treatment. Mated female flies were frozen 6 h after mating and RNA extracted. Two biological replicates per cross per population (2x2x8=32 samples).

Mapping active promoters by ChIP-seq profiling of H3K4me3 in cichlid fish - a first step to uncover cis-regulatory elements in ecological model teleosts

Project description:Evolutionary alterations to cis-regulatory sequences are likely to cause adaptive phenotypic complexity, through orchestrating changes in cellular proliferation, identity and communication. For non-model organisms with adaptive key-innovations, patterns of regulatory evolution have been predominantly limited to targeted sequence-based analyses. Chromatin-immunoprecipitation with high-throughput sequencing (ChIP-seq) is a technology that has only been used in genetic model systems and is a powerful experimental tool to screen for active cis-regulatory elements. Here, we show that it can also be used in ecological model systems and permits genome-wide functional exploration of cis-regulatory elements. As a proof of concept, we use ChIP-seq technology in adult fin tissue of the cichlid fish Oreochromis niloticus to map active promoter elements, as indicated by occupancy of trimethylated Histone H3 Lysine 4 (H3K4me3). The fact that cichlids are one of the most phenotypically diverse and species-rich families of vertebrates could make them a perfect model system for the further in-depth analysis of the evolution of transcriptional regulation. examination of H3K4me3 in adult fin tissue of the Nile tilapia (Oreochromis niloticus)
