Expression data from D. melanogaster pupal wings

ABSTRACT: The goal of this gene expression profiling experiment was to identify the entire set of transcription factors expressed during late pupal wing development (~80h APF) when pigmentation genes are expressed We used Affymetrix microarrays to profile the expression of the transcription factors in late pupal wings of Oregon R flies. The staging of the flies was made by eye, based on the extent of wing pigmentation. RNA was extracted from batches of 40 flies and three biological replicates were analyzed.

The typical pattern of morphological evolution associated with the radiation of a group of related species is the emergence of a novel trait and its subsequent diversification. Yet the genetic mechanisms associated with these two evolutionary steps are poorly characterized. Here, we show that a spot of dark pigment on fly wings emerged from the assembly of a novel gene regulatory module in which a set of pigmentation genes evolved to respond to a common transcriptional regulator determining thei ...[more]

Project description:Hox genes regionalize the animal body axis by modifying complex morphogenetic and differentiation processes during development. The transformation of wings into halteres by the Hox gene Ultrabithorax (Ubx) in Drosophila melanogaster presents an excellent model system to study the transcriptional networks that control such complex developmental programmes. We have employed an inducible misexpression system to switch on Ubx in the wing epithelium at successive larval, prepupal and pupal stages, and have used microarray expression profiling to identify the primary transcriptional responses to Ubx. We find that Ubx regulates hundreds of downstream genes, mostly in a subtle manner. These targets are largely distinct at the different stages of appendage development and diversification. We have generated an experimental fly line combining the nabGal4NP3537-driver, a tub-GAL80ts transgene, and a UAS-UbxIa transgene (the control line was carrying a UAS-eGFP transgene instead). Our core microarray analysis has involved comparison of the transcriptional profile of experimental wings carrying the UAS-UbxIa transgene with that of control wings carrying the UAS-eGFP transgene. Pairwise comparisons have been carried out at three successive developmental stages, in particular at (i) the third instar larval wandering stage, about 4hrs before puparium formation at 29˚C, (ii) the prepupal stage, 6hrs after puparium formation (APF) at 29˚C, and (iii) the early pupal stage, 16hrs APF at 29˚C. Moreover, pairwise comparisons have been carried out with samples developed exclusively at 19˚C (UbxIa or eGFP expression OFF), as well as with samples collected at 16hrs after the temperature shift from 19 to 29˚C (UbxIa or eGFP expression ON). This has allowed us to distinguish the Ubx-dependent effects from the intrinsic expression differences between the fly lines used, and from the temperature-induced responses. We have carried out 4 biological replicates for each condition making a total of 48 hybridizations to Affymetrix Drosophila Genome 2.0 arrays.

Project description:We generated RNA-seq data of Drosophila simulans and Drosophila mauritiana developing male genitalia in order to identify expression level differences between these species. These species are closely related, yet have dramatic differences in their male genital morphologies. Three independent RNA-seq library replicates were generated for Dsim w501 and Dmau D1 developing male genitalia. Flies were reared under the above conditions, and white pre-pupae collected. Males were selected using gonad size and allowed to develop in a humid container at 25ºC until stages 2 and 4.5 (see staging guide in (Hagen et al., 2019); tartan underlies the evolution of Drosophila male genital morphology). Between these stages, the claspers develop from a ridge structure to a distinct appendage separate from the surrounding tissue, and the posterior lobe has begun to extend outwards from the lateral plate primordia (Hagen et al., 2019). The heads of pupae were impaled with a needle onto a charcoal agar plate and submerged in 1xPBS. Dissection scissors were used to remove the distal tip of the pupal case and the outer membrane, and pressure applied to the abdomen to allow the developing genitalia to be quickly expelled from the pupal case and dissected away from the abdomen. Note that the entire genital arch, including internal genital organs (but not including abdominal tissue), was isolated for RNA extraction. The genitalia from fifteen males from each stage were collected and placed directly into TRIzol. RNA was then extracted using standard procedures. Quality and quantity of RNA was verified using a Qubit, and samples were sent to the Centre for Genomic Research at the University of Liverpool where dual-indexed, strand-specific RNA-seq libraries were prepared using NEBNext polyA selection and Ultra Directional RNA preparation kits. Samples were then sequenced using Illumina HiSeq 4000 (paired-end, 2x150 bp sequencing). Dsim w501 and Dmau D1 reads were mapped against reannotated reference coding sequences (Torres-Oliva et al., 2016).

Project description:We investigated gene expression levels in Heliconius erato butterflies with divergent wing patterns across a 656KB genomic interval linked to the red color pattern wing polymorphism. This included comparison of expression between two H. erato color pattern populations (H. e. petiverana and a H.e. etylus x H. himera hybrid) across three sections of the forewing that differed in pigmentation (the basal, mid, and distal wing sections) and five different stages of pupal development (Day 1, 3, 5 pupae and ommochrome and melanin pigmentation stages). These results allowed us to determine whether certain genes in this interval were differentially expressed between the wing pattern elements, and, therefore, potentially responsible for adaptive color pattern variation in these butterflies. Forewings from a total of 29 individuals, covering three biological replicates of five developmental time points for each of the two H. erato distinct phenotypes were dissected, with the only exception being that there were only two replicates of the day 1 hybrid phenotype. Individuals were reared at 25˚C and dissected at the following stages: a) day 1 = 12 hr after pupation; b) day 3 = 60 hr after pupation; c) day 5 = 108 hr after pupation; d) early ommochrome = ~ 156 hr after pupation when red scales in forewing partially mature, showing a pale orange color; and e) early melanin = ~ 180 hr after pupation melanic scales begin to turn black and are present primarily at the center of the wing. Using wing veins as landmarks, each forewing was cut into three sections corresponding to the color pattern boundaries: basal (F1), middle (F2), and apical (F3). A eight custom-designed Roche NimbleGen 12x135K format microarrays with probes spanning a 656,307bp genomic region (Roche NimbleGen Inc., Madison, Wisconsin, United States) were used to hybridize double stranded cDNA from 87 tissue samples. Repetitive sequence elements found more than five times across all currently available H. erato genomic sequences, including the probed region as well as additional genomic BAC sequences, were masked from the tiling region. The remaining unmasked non-repetitive genomic sequences were tiled using 60 bp probes staggered every 13 bp on average, with slight modifications to ensure probe quality, for a total of 48,547 probes. Microarry design and printing was performed by Roche NimbleGen. cDNA labeling, hybridization, and array scanning was performed by the City of Hope Microarray Facility (Duarte, California, United States). In addition to the probes from the red color pattern intervals, the arrays also include 40,763 probes across two other genomic intervals not addressed in this study, 45,046 probes representing 12450 transcripts from a recent transcriptome assembly at 1-6X coverage, and 3248 random probes. Results from the transcriptome and other color pattern intervals will be published separately, however, we analyzed all probes together for array normalization and quality control.

Project description:In the eastern United States the buckeye butterfly, Junonia coenia, shows a seasonal wing color polyphenism where adults emerging in the spring are pale brown, while those emerging in the autumn are dark red. This variation can be artificially induced in laboratory colonies, thus making J. coenia a useful model system to examine the developmental basis of phenotypic plasticity. We used RNA-seq to generate the first set of assembled transcripts for this species while simultaneously quantifying relative gene expression associated with development of alternative seasonal color morphs. The assembled consolidated wing transcriptome was 77.55 Mb. 16,251 contigs of over 1000bp in length were assembled, of which 3,145 were differentially expressed between stages and/or color morphs. Depending on the developmental stage, between 547 and 1420 transcripts were significantly differentially expressed between brown and red wing morphs. These extensive differences in gene expression stand in stark contrast to the much smaller numbers found in previous studies on genetic wing pattern variation, and suggest that environmentally induced phenotypic shifts may arise from very broad systemic processes. Overall gene ontology (GO) analyses revealed that genes associated with structural constituents of ribosomes and oxygen transport were significantly upregulated in the pale brown morph, while genes associated with peptidase activity were very significantly upregulated in the dark red morph. Focused analyses of candidate endocrine and pigmentation pathways revealed a number of notable genes upregulated in the red morph, including several ecdysone-related genes and cinnabar, an ommochrome pigment gene implicated in color pattern variation in other butterflies. Surprisingly, we found numerous melanin-related transcripts, including tan and yellow-family genes, strongly upregulated in the red morph, leading us to speculate that red pigmentation in autumn J. coenia may include red or brown melanins in addition to ommochromes. While we identified several endocrine and pigmentation genes as obvious candidates for color morph differentiation, we speculate that the majority of gene expression differences we observed were due to thermal stress response. The buckeye transcriptome provides a basis for further developmental studies of phenotypic plasticity. mRNA profiling of hind wings from 4 developmental stages of two color morphs (Rosa and Linea) of the buckeye butterfly (J. coenia), generated by deep sequencing, in triplicate, using Illumina GAII or HiSeq 2000.
