Ectodini cichlid brain comparison of mating type

Project description: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.

Recombination suppression on fungal mating-type chromosomes without mating-type loci linkage and with loss of function of HD mating-type genes

Project description:So as to compare fungal mating-type chromosomes across a range of Microbotryum species, comparative genomics analyses were conducted, and were informed by RNASeq data. In this instance, different stages of the lifecycle of M. violaceum infecting D. pavonius were compared via RNASeq.

Epigenetic regulation of gonadal and brain aromatase expression in a cichlid fish with environmental sex determination

Project description:We examined the methylation state of upstream intergenic regions associated with two aromatase genes (cyp19a1A and cyp19a1B) in P. pulcher, a cichlid fish with pH-based sex and male morph determination. Methylation levels in fry head and trunk and adult brain and gonad samples were assessed with a bisulfite amplicon sequencing assay and sequence data was processed through two pipelines to determine % methylation of individual CpG sites and abundance of specific patterns of methylated and unmethylated CpGs (i.e., epialleles).

Mating-type specific gene expression in the filamentous ascomycete Neurospora tetrasperma

Project description:Neurospora tetrasperma is a pseudohomothallic filamentous ascomycete with a large (~ 7 Mbp) region of suppressed recombination surrounding its mating-type (mat) locus. The suppressed recombination has lead to sequence divergence between the two mating-type chromosomes of wild-type heterokaryotic strains, while the remaining genome is largely homoallelic. In this study, we use microarray technology to manifest expression divergence linked to mating type in N. tetrasperma. N. tetrasperma and N. crassa, were grown on agar regimes inducing sexual growth (Synthetic Crossing medium) and vegetative growth (Vogel's Medium), respectively.

Dynamic, mating-induced gene expression changes in female head and brain tissues of Drosophila melanogaster

Project description:Temporal gene expression changes in head tissues from mated females was determined at four time points post-mating, from 0-2 hours out to 72 hours. Each time point assayed post-mating showed a unique post-mating gene expression response, with 48 hours post-mating having the largest number of genes with expression changes. At most time points, a marked change in expression of genes expressed in the head fat body and encode products that function in metabolism was observed. Additionally, gene expression was analyzed at 24 hours post-mating in brain tissues, identifying the repressed expression of several genes encoding ion channels.

Mating response of three yeast species (S. cerevisiae, S. paradoxus and S. mikatae)

Project description:We examined the mating response of three yeast species, by subjecting a-type cells from each of them to alpha-factor (6uM). The expression of cells before and after (60min) addition of alpha-factor were compared using S. cerevisiae cDNA microarrays. In addition, we verified our results with a true mating experiment: the expression of a-type and alpha-type cells from S. cerevisiae were compared before and after mixing them for 90 minutes (i.e. allowing them to mate). Keywords: yeast mating response, comparison among species
