Project description:Investigation of whole genome transcription expression level changes in Drosophila mojavensis wild-type populations (1 Punta Onah: PO, 2 Organ Pipe National Monument: OPNM, 3 Punta Prieta:PP, and 4 San Quintin: SQ). The experiment was designed to investigate functional genomic responses to temperature variation (15, 25, and 35 °C) in adult Drosophila mojavensis wild populations. For each treatment 1-5 replicates were used (R1, R2, R3, R4 & R5). SO and BC represents Sonora deserts and Baja California region respectively.

The experiment was designed to investigate functional genomic responses to temperature variation (15, 25, and 35 °C) in adult Drosophila mojavensis wild populations. For each treatment 1-5 replicates were used (R1, R2, R3, R4 & R5). SO and BC represents Sonora deserts and Baja California region respectively. A total of 97 hybridizations were performed in this entire experiment. We used 135K 12-plex NimbleGen arrays. Total RNA was recovered from each sample listed below. The experimental design consisted a total of four populations (Punta Onah:PO; Organ Pipe National Manument:OPNM, Punta Prieta:PP and San Quintin:SQ), two host diets (Agria:AG and Organ pipe:OP) and three temperature treatments (15, 25 and 35 °C). Each chip measures the expression level of 14528 transcripts. One to 5 replicates were used for each type (R1, R2, R3, R4 and R5). Fly source details are as follows: Punta Onah 2007:PO07; Organ Pipe National Monument 2008:OPNM08; Punta Prieta 2008:PP08; San Quintin 2008:SQ08.

Project description:It is unclear how epigenetic changes regulate the induction of erythroid-specific genes during terminal erythropoiesis. Here we use global mRNA sequencing (mRNA-seq) and chromatin immunoprecipitation coupled to high-throughput sequencing (CHIP-seq) to investigate the changes that occur in mRNA levels, RNA Polymerase II (Pol II) occupancy and multiple post-translational histone modifications when erythroid progenitors differentiate into late erythroblasts. Among genes induced during this developmental transition, there was an increase in the occupancy of Pol II, the activation marks H3K4me2, H3K4me3, H3K9Ac and H4K16Ac, and the elongation methylation mark H3K79me2. In contrast, genes that were repressed during differentiation showed relative decreases in H3K79me2 levels yet had levels of Pol II binding and active histone marks similar to those in erythroid progenitors. We also found that relative changes in histone modification levels-in particular, H3K79me2 and H4K16ac-were most predictive of gene expression patterns. Our results suggest that in terminal erythropoiesis both promoter and elongation-associated marks contribute to the induction of erythroid genes, while gene repression is marked by changes in histone modifications mediating Pol II elongation. Our data maps the epigenetic landscape of terminal erythropoiesis and suggests that control of transcription elongation regulates gene expression during terminal erythroid differentiation. Mouse fetal liver cells are double-labeled for erythroid-specific TER119 and non erythroid-specific transferrin receptor (CD71) and then sorted by flow-cytometry. E14.5 fetal livers contain at least five distinct populations of cells (R1 through R5); as they progressively differentiate they gain TER119 and then gain and subsequently lose CD71. CFU-E cells and proerythroblasts make up the R1 population; R2 consists of proerythroblasts and early basophilic erythroblasts; R3 includes early and late basophilic erythroblasts; R4 is mostly polychromatophilic and orthochromatophilic erythroblasts; and R5 is comprised of late orthochromatophilic erythroblasts and reticulocytes. We have sorted for R2-R5 cells for RNA-seq experiment.

Project description:Rhombomeres serve to position neural progenitors in the embryonic hindbrain, thereby ensuring appropriate neural circuit formation, but the molecular identities of individual rhombomeres and the mechanism whereby they form have not been fully established. Here we apply scMultiome analysis in zebrafish to molecularly resolve all rhombomeres for the first time. We find that rhombomeres become molecularly distinct between 10hpf (end of gastrulation) and 13hpf (early segmentation). While the mature hindbrain consists of alternating odd- versus even-type rhombomeres, our scMultiome analyses do not detect extensive odd versus even characteristics in the early hindbrain. Instead, we find that each rhombomere displays a unique gene expression and chromatin profile. Prior to the appearance of distinct rhombomeres, we detect three hindbrain progenitor clusters (PHPDs) that correlate with the earliest visually observed segments in the hindbrain primordium and that represent prospective rhombomere r2/r3 (possibly including r1), r4 and r5/r6, respectively. We further find that the PHPDs form in response to Fgf and RA morphogens and that individual PHPD cells co-express markers of multiple mature rhombomeres. We propose that the PHPDs contain mixed-identity progenitors and that their subdivision into individual mature rhombomeres requires resolution of these mixed-identity cell states.

Project description:To characterize the sequence of events associated with RasV12 immortalization of Drosophila embryonic cells, we generated transcriptional time series during cell line establishment, from primary cultures until passage (P) 19. We generated three transcriptional time series from three cell lines (R1, R4 and R5) by sampling the cultures at successive stages, early (P2-4), intermediate (P4-11), and late (P16-19), characterized by different passage times. Time points for the R1 time-series were: P2, P3, P4, P5, P7, P8, P10, P11, P16, P17 and P19; for the R4 time-series: P2, P3, P4, P5, P6, P7, P9, P11, P12, P16, P17 and P19; and for the R5 time-series: P2, P3, P4, P6, P7, P8, P16, P17 and P19

Project description:Maize kernels are susceptible to infection by the opportunistic pathogen Aspergillus flavus. Infection results in reduction of grain quality and contamination of kernels with the highly carcinogenic mycotoxin, aflatoxin. To understand host response to infection by the fungus, transcription of approximately 9,000 maize genes were monitored during the host-pathogen interaction with a custom-designed Affymetrix GeneChip® DNA array. More than 1,000 maize genes were found differentially expressed at a fold change of 2 or greater. This included the up regulation of defense-related genes and signaling pathways. Transcriptional changes also were observed in primary metabolism genes. Starch biosynthetic genes were down regulated during infection, while genes encoding maize hydrolytic enzymes, presumably involved in the degradation of host reserves, were up regulated. These data indicate that infection of the maize kernel A. flavus induced metabolic changes in the kernel, including the production of a defense response, as well as a disruption in kernel development. Maize kernels were mock inoculated at the blister (R2) or dough (R4) stage or inoculated with A. flavus at the blister (R2), milk (R3), dough (R4), or dent (R5) stage, and harvested 4 days later. Each treatment consisted of three biological replications. For each biological replication, 8 kernels were ground and RNA was isolated and further processed.
