Project description:The use of statistical tools established for the genetic analysis of quantitative traits can be applied to gene expression data. Quantitative trait loci (QTL) analysis can associate expression of genes or groups of genes with particular genomic regions and thereby identify regions that play a role in the regulation of gene expression. A segregating population of 41 doubled haploid (DH) lines from the hard red spring wheat cross RL4452 x AC Domain was used. This population had previously been mapped with microsatellites and includes a full QTL analysis for agronomic and seed quality traits. Expression analysis from 5 day post anthesis developing seed was conducted on 36 of the 41 DH lines using the Affymetrix wheat array. Expression analysis of developing seeds from field grown material in location 2 identified 10,280 sequences represented by Affymetrix probe sets whose expression varied significantly between genotypes of the population. Of these 1,455 were identified in the point location as well. A sub-set of 542 transcripts were identified that each mapped to a single chromosome interval illustrating that major expression QTLs can be found in wheat. Genomic regions corresponding to multiple expression QTLs were identified that were coincident with previous identified seed quality trait QTL. These regions may be important regulatory regions governing economically important traits. Comparison of expression mapping data with physical mapping for a sub-set of sequences showed that both cis and trans acting expression QTLs were present. Experiment Overall Design: Parental genotypes of mapping population RL4452 x AC Domain with 2 biological replicates per genotype. Grown in the field in a lattice design at SB location with the 41 DH progeny lines.

Project description:In the fire ant Solenopsis invicta, a colony queen number is determined by the founding queen's genotypes at the 13 Mb supergene with the non-recombining variants SB and Sb. Single-queen colonies are always headed by SB/SB queens while multiple-queens colonies are always headed by SB/Sb queens. The two variants of the supergene, SB and Sb are completely linked to the two alleles (B and b) of the gene Gp-9. SB/SB and SB/Sb queens differ in many physiological traits including their maturation rate and odor. To explain why SB/SB and SB/Sb queens have different odors, and why SB/SB virgins mature faster and accumulate more fat, we measured expression of ~6000 genes in virgin queens 1 and 11 days after eclosion and in reproductive queens. Keywords: fire ants, Solenopsis invicta, Supergene, queen, Gp-9, social form, maturation, fat storage, queen odor, cuticular hydrocarbon, worker discrimination, monogyne, polygyne, transposon, chemical signaling

Biological replicates: 8 for 1-day-old SB/SB virgins and 1-day-old SB/Sb virgins that were collected in 2008; 8 for 1-day-old SB/SB virgins, 1-day-old SB/Sb virgins that were collected in 2009; 7 for 11-day-old SB/SB virgins and 11-day-old SB/Sb virgins that were collected in 2008; 8 for 11-day-old SB/SB virgins and 11-day-old SB/Sb virgins that were collected in 2009; 8 for SB/SB and SB/Sb reproductive queens (only collected in 2009). Samples were labeled with Cy3 and were compared to the same common reference RNA labeled with Cy5. Samples from 2008 were hybridized on the microarrays batch I and samples from 2009 were hybridized on the microarrays batch J.

Project description:Recent epidemiological studies suggest that hyponutritional stress during fetal period increase risks of adult-onset diseases, such as type 2 diabetes and mental diseases. Rodent models have demonstrated that hyponutrition during pregnancy alters epigenetic status of neuronal genes in the fetal brains; this implicate fatal environment contributes to susceptibility to mental disorders. However, in these studies, progenies were generated with natural mating and effects of hyponutrition during egg formation have not been eliminated. Therefore, we conducted experiments in order to finely evaluate the hyponutritional effects during fatal life using in vitro fertilization. We divided three experimental groups such as control diet (CD (AIN93G)), protein-restricted diet (PR), and PR diet with supplemental folic acid (FA) and compared body weight of mother and progenies, clinical-blood biochemistry, DNA methylation and gene-expression pattern in adult brain of the progenies, behavioral phenotypes of the progenies, and DNA methylation profile in brain of the progenies. The progenies of the PR group and the FA group exhibited increased activity in the home cage, decreased contact to a novel object, and decreased social behavior compared with the CD group. Increased home-cage activity in the PR group was rescued in the FA group. The progenies of the PR group and the FA group showed different patterns of mRNA expression and genomic methylation in the brain compared with the CD group. These results suggest that hyponutrition after insemination sufficiently induced phenotypic and epigenetic changes in the progenies. In addition, supplemental nutrition to mothers should rescue the epigenetic and phenotypic changes induced with hyponutrition.
