Project description:Temnothorax is a large myrmicine ant genus with a range spanning the northern hemisphere, including the northern half of the Neotropics. Many of the Neotropical species were originally placed in the now defunct genus Macromischa. Recent molecular work has revealed that distinct lineages of Neotropical Temnothorax have arrived by evolutionary convergenceat a morphological syndrome with characteristics that were used to diagnose the former genus Macromischa. One such lineage is the salvini clade, which in this study is redefined to contain 63 species, 35 of which are described as new. A key to all species of the salvini clade based on the worker caste is provided; additionally, a worker-based key to all clades of the New World is provided. The following species are redescribed: T. albispinus (Wheeler), T. androsanus (Wheeler), T. annexus (Baroni Urbani), T. augusti (Baroni Urbani), T. aztecus (Wheeler), T. ciferrii (Menozzi & Russo), T. flavidulus (Wheeler & Mann), T. fuscatus (Mann), T. goniops (Baroni Urbani), T. huehuetenangoi (Baroni Urbani), T. ixili (Baroni Urbani), T. leucacanthus (Baroni Urbani), T. nigricans (Baroni Urbani), T. ocarinae (Baroni Urbani), T. pastinifer (Emery), T. pergandei (Emery), T. politus (Smith), T. pulchellus (Emery), T. rugosus (Mackay), T. salvini (Forel), T. schwarzi (Mann), T. skwarrae (Wheeler), T. subditivus (Wheeler), T. tenuisculptus (Baroni Urbani), T. terricola (Mann), T. terrigena (Wheeler), T. torrei (Aguayo). The gynes of T. ciferrii, T. fuscatus, T. ixili, T. politus, T. rugosus, T. salvini, T. tenuisculptus and T. torrei are described. The males of T. albispinus and T. fuscatus are described. Lectotypes are designated for T. androsanus, T. annexus, T. augusti, T. aztecus, T. flavidulus, T. fuscatus, T. nigricans, T. pastinifer, T. pergandei, T. politus, T. pulchellus, T. salvini, T. skwarrae, T. subditivus, T. terricola, and T. terrigena. A neotype for Temnothorax salvini obscurior (Forel) is designated, the taxon is raised to species, and a replacement name is designated: T. longicaulis stat. nov., nom. nov. The following species are described as new: T. achii sp. nov., T. acuminatus sp. nov., T. acutispinosus sp. nov., T. agavicola sp. nov., T. altinodus sp. nov., T. arbustus sp. nov., T. aureus sp. nov., T. aztecoides sp. nov., T. bahoruco sp. nov., T. balaclava sp. nov., T. balnearius sp. nov., T. bison sp. nov., T. casanovai sp. nov., T. fortispinosus sp. nov., T. harlequina sp. nov., T. hippolytus sp. nov., T. laticrus sp. nov., T. leucacanthoides sp. nov., T. longinoi sp. nov., T. magnabulla sp. nov., T. misomoschus sp. nov., T. nebliselva sp. nov., T. obtusigaster sp. nov., T. paraztecus sp. nov., T. parralensis sp. nov., T. parvidentatus sp. nov., T. pilicornis sp. nov., T. quercicola sp. nov., T. quetzal sp. nov., T. rutabulafer sp. nov., T. terraztecus sp. nov., T. tuxtlanus sp. nov., T. wettereri sp. nov., T. wilsoni sp. nov., T. xincai sp. nov.

Project description:modENCODE_submission_5986 This submission comes from a modENCODE project of Jason Lieb. For full list of modENCODE projects, see http://www.genome.gov/26524648 Project Goal: The focus of our analysis will be elements that specify nucleosome positioning and occupancy, control domains of gene expression, induce repression of the X chromosome, guide mitotic segregation and genome duplication, govern homolog pairing and recombination during meiosis, and organize chromosome positioning within the nucleus. Our 126 strategically selected targets include RNA polymerase II isoforms, dosage-compensation proteins, centromere components, homolog-pairing facilitators, recombination markers, and nuclear-envelope constituents. We will integrate information generated with existing knowledge on the biology of the targets and perform ChIP-seq analysis on mutant and RNAi extracts lacking selected target proteins. For data usage terms and conditions, please refer to http://www.genome.gov/27528022 and http://www.genome.gov/Pages/Research/ENCODE/ENCODEDataReleasePolicyFinal2008.pdf EXPERIMENT TYPE: CHIP-seq. BIOLOGICAL SOURCE: Strain: N2; Developmental Stage: L3 Larva; Genotype: wild type; Sex: mixed Male and Hermaphrodite population; EXPERIMENTAL FACTORS: Developmental Stage L3 Larva; temp (temperature) 20 degree celsius; Strain N2; Antibody NURF-1 SDQ3525 (target is NURF-1)

Project description:Trithorax group (TrxG) proteins counteract Polycomb silencing by an as yet uncharacterized mechanism. A well-known member of the TrxG is the histone methyltransferase Absent, Small, or Homeotic discs 1 (ASH1). In Drosophila ASH1 is needed for the maintenance of Hox gene expression throughout development, which is tightly coupled to preservation of cell identity. In order to understand the molecular function of ASH1 in this process, we performed affinity purification of tandem-tagged ASH1 followed by mass spectrometry (AP-MS) and identified FSH, another member of the TrxG as interaction partner. Here we provide genome-wide chromatin maps of both proteins based on ChIP-seq. Our Dataset comprises of 4 ChIP-seq samples using chromatin from S2 cells which was immunoprecipitated, using antibodies against Ash1, FSH-L and FSH-SL.

Project description:Seeds are comprised of three major parts of distinct parental origin: the seed coat, embryo, and endosperm. The maternally-derived seed coat is important for nurturing and protecting the seeds during development. By contrast, the embryo and the endosperm are derived from a double fertilization event, where one sperm fertilizes the egg to form the diploid zygote and the other sperm fertilizes the central cell to form the triploid endosperm. Each seed part undergoes distinct developmental programs during seed development. What methylation changes occur in the different seed parts, if any, remains unknown. To uncover the possible role of DNA methylation in different parts of the seed, we characterized the methylome of three major parts of cotyledon stage seeds, the seed coat, embryonic cotyledons, and embryonic axis, using Illumina sequencing. Illumina sequencing of bisulfite-converted genomic DNA from three parts of soybean cotyledon stage seeds: seed coat (COT-SC), embryonic cotyledons (COT-COT), and embryonic axis (COT-AX).
