Project description:We create catalogues of genes showing significant strain, parent-of-origin, dominance, sex effect in inbreds and reciprocal F1 hybrids of three wild-derived strains (CAST, PWK, WSB) across 4 different tissues (brain, kidney, liver, and lung) We used microarrays to validate the Brain results of RNAseq from inbred and F1 of 3 by 3 diallel. Brain, liver, kidney and lung RNA from the same mice used for RNAseq were hybridized to Affymetrix Mouse Gene 1.1 ST 96-Array Plate arrays using a GeneTitan instrument from Affymetrix.

Project description:We used a reciprocal cross of Mus musculus and M. domesticus in which F1 males are sterile in one direction and fertile in the other direction, in order to associate expression differences with sterility. Four different crosses were performed. A cross between two strains within each mouse species (M. musculus, PWK/PhJ and CZECHII/EiJ; M. domesticus, LEWES/EiJ and WSB/EiJ). And two reciprocal crosses between a domesticus (LEWES/EiJ) and a musculus (PWK/PhJ) strain. The cross between a musculus female and a domesticus male produces sterile male offspring - whereas all other crosses produced fertile male offspring. Testis tissue from three male mice (60 days old) from all four crosses were analysed on the Affymetrix MG 430.2. Array.

Project description:Non-additive gene regulation has been recently suggested as an important factor promoting phenotypic variation and plasticity. In order to obtain a description of gene expression status at an early stage of ear development in a maize (Zea mays L.) F1 hybrid as relative to its parental inbreds, we compared gene expression profiles in immature ears of elite inbred lines B73 and H99 to one of their F1 hybrids (B73xH99) using cDNA microarray technology. Results show several genes expressed at a significantly different level between both inbred lines and their hybrid. In addition, gene expression non-additivity in the hybrid was detected on a broad scale, consisting of both dominance and over-dominance components, indicating that complex non-additive interactions at the molecular level exist in the developing ear of the studied maize hybrid. Non-additively regulated genes belong to a wide range of molecular functions, indicating that several regulatory and metabolic patterns are possibly affected during ear development in the investigated hybrid. We discuss the possibility that observed gene expression non-additivity in immature ear might be an early molecular manifestation of hybrid vigor, the most exploited factor for maize agronomic improvement.

We discuss the possibility that observed gene expression non-additivity in immature ear might be an early molecular manifestation of hybrid vigor, the most exploited factor for maize agronomic improvement. We directly contrasted both B73 and H99 inbred lines vs. their F1 heterotic hybrid transcriptomes in immature ear. Our experimental design consisted of 10 cDNA microarray hybridizations, 5 for each combination of hybrid vs. inbred genotypes, involving 20 separate labeling reactions. Labeling dyes were swapped in two of the five replicates for each combination. In each hybridization, control channel was assigned to the F1 hybrid, and differences in transcriptional levels between B73 and H99 were inferred using the hybrid as a common reference sample in an indirect experimental design. To take in account variability in transcript population among individuals, total RNA coming from different isolations, each collected on multiple individuals, were mixed before poly(A+) RNA purification. All hybridizations on microarray slides were then performed using cDNA independently labeled from the poly(A+) RNA purification product for each genotype. Base-two logarithms of expression ratios were subjected to one-class response significance analysis in SAM v. 2.20 software [Tusher et al. 2001]. For each EST the estimates of additive parameter "a" and dominance parameter "d" (middle-parent heterosis) were obtained as a = (L2 – L1)/2 d = (L1 + L2)/2 (where L1 and L2 are mean base-two logarithms of expression ratios of F1 vs. B73 and F1 vs. H99, respectively). Positive values of "a" indicate expression values bigger in B73 than in H99. The dominance/additivity ratio (d/|a|) was also calculated [Falconer 1989]. Evaluation of statistical significance of parameters was done by calculating standard errors of the estimates "a" and "d" as standard errors of linear functions of the means. Significance testing was done correspondingly, using an F-test for linear contrasts. P-values for the families of tests corresponding to each parameter were subjected to global error analyses using a method based on fitting mixture distribution [Allison et al. 2002], allowing to estimate the false discovery rates (FDR) and false negative rates (FNR). Confidence intervals for d/|a| ratios were obtained by Fieller’s method [Piepho and Emrich 2005], allowing to classify the genes into different dominance type classes.

Project description:We report 2,649 crossover breakpoints identified by single-cell DNA sequencing of 217 sperm in a B6xCAST F1 mouse, which is heterozygous at Prdm9, with one wild-type CAST allele and one allele found in human populations (bred from a genetically engineered mother, Davies et al Nature 2012). Separately, we have reported testis DMC1 enrichment in the same mouse (GSE124991). We also infer H3K4me3 intensities at DMC1 hotspots, based on the raw H3K4me3 ChIP-seq data published under GSE119727 (Li et al). We identify several factors, including PRDM9 binding on the repair-template homologue, telomere proximity and local GC-content, that affect the probability that a DSB is repaired as a crossover. We further show that these factors also influence the time it takes for the site of a DSB to find and engage its homologue, with rapidly-engaging sites being more likely to be repaired as crossovers.

Project description:We sought to evaluate the brain gene expression profiles of male courtship display. To assess male display and courtship behavior, we designed a courtship preference assay. We evaluated social interactions between males and females using a 40 gallon tank design with a ‘rock’ habitat at one end and ‘sand’ at the other, separated by glass bottom. When parental rock species (Petrotilapia nigra (TaxId 526958), Maylandia zebra (TaxId 106582), Labeotropheus feulliborni) are placed in this tank paradigm, males court females over the rocks. Males of sand species (Mchenga conophorus, Aulonocara baenschi (TaxId 143496), Tramitichromis intermedius (TaxId 323801)) court females over sand and construct species appropriate bowers. When single rock x sand F1 males were placed in this set up with F1 females, males invariably courted females over the ‘rock’ habitat, suggesting genetic dominance. When two rock x sand F1 males were allowed to compete for F1 females in this tank paradigm, something interesting happened. One male, typically the larger, courted females over the rock habitat, and the other simultaneously constructed bowers to court females in the sand. We detected no difference in GSI (gonadal somatic index) between F1 males behaving as ‘socially rock’ vs. ‘socially sand.’ This observation of divergent behavior among interacting F1 brothers suggests an interaction between the genome and the social environment in these males.
