FlyBase:Insertion Report

Jump to: navigation, search

Last Updated: 15 Dec. 2017

The insertion report is used to present data on insertions of transgenic constructs, insertions of natural transposons in the sequenced strain, and insertions of natural transposons in strains other than the sequenced strain.

This is a field-by-field guide to the information in the Insertion Report.

General Information

Symbol The valid symbol that is used in FlyBase for the insertion. If the insertion results in a described allele, the allele symbol is included within the insertion symbol.

The first part of the symbol (before the '\') is the standard prefix for the species (from the Species Abbreviations list). For species other than D.melanogaster, the species prefix is displayed wherever the gene symbol is used throughout FlyBase. For D.melanogaster genes, the species prefix is only displayed in the General Information section at the top of a report.

Name This field is not used for insertions of transgenic constructs and transposons.
Feature type A single controlled vocabulary term from the Sequence Ontology (SO), which describes this sequence entity. The feature type transposable_element_insertion_site is used for two classes: insertions of transgenic constructs and insertions of natural transposons into a strain other than the sequenced strain. If mapping data are available, these insertion classes may be mapped to a single site on the sequenced genome. The feature type transposable_element is used for the third class, natural transposons in the sequenced strain. This class is mapped to an extent (or region) on the sequenced genome, corresponding to a specific individual transposon within the sequenced strain (at the time it was sequenced).
Species The organism in which this specific insertion exists, with the initial letter of the genus and the full species name listed.
FlyBase ID The Primary FlyBase identifier number of the insertion, used to uniquely identify the insertion in the database.

An insertion may also have any number of Secondary FlyBase identifier numbers, which are listed in the Secondary FlyBase IDs section of the Insertion Report.

Description

Inserted element This field contains the transposable-element based transgenic construct inserted or the natural transposon class inserted. Clicking on the symbol will take you to the relevant Recombinant Construct Report or Natural Transposon Report as appropriate. Detailed information is to be found in the Inserted Element section, below.
Affected gene(s) Gene(s) reported to be affected by the insertion (hyperlinked to the relevant Gene Report); the insertion may be located within the transcribed extent of the gene, and/or may cause misexpression or a reduction in expression. This field includes both genes within the genomic region surrounding the insertion and also genes carried in the inserted element. Detailed information is to be found in the Affected Gene(s) section, below.
Causes allele(s) Allele(s) created by the presence of the insertion (hyperlinked to the relevant Allele Report). This field includes both alleles of genes within the genomic region surrounding the insertion and also alleles carried in the inserted element. Detailed information is to be found in the Alleles and Phenotypes section, below.
LINE ID The line identification number used by one of the large-scale gene disruption projects (eg., the BDGP, the GDP, or DrosDel), if relevant. A line identification number refers to an isolated genetic line, and thus may apply to more than one insertion, if multiple insertions are co-isolated. Additional information is to be found in the Data on Genetic Line section, below.
Expression data If Ecol\lacZ enhancer trap expression data or Scer\GAL4 reporter/driver data have been curated for this specific insertion, it is indicated by "lacZ reporter" or "GAL4 reporter/driver". Detailed information is to be found in the Expression Data section, below.
Viability/fertility This field is populated if the homozygous stock has been reported as "viable" and/or "fertile". Lethal or sterile phenotypes are not reported; this information is reported in the Alleles and Phenotypes section, below.
Stock availability If stocks of this insertion are available, it is indicated by "publicly available" (if available from one of the public stock centers) or "not publicly available" (if stock may be available from an individual lab). Specific information may be found in the Stocks section, below.

Genomic Location

Chromosome location The chromosome arm on which the insertion is located, followed by cytological location in parentheses. See Computed cytological data in FlyBase for a detailed description of how this computed cytological location is calculated. See the Detailed Mapping Data section, below, for sources of these data.
Sequence location Site of insertion on the genomic sequence, if mapped to the sequenced strain. If the precise point of insertion is not known, this value may be a range. Includes orientation of the inserted element relative to the conventional representation of the chromosome arm (if also reported), indicated in brackets. See the Detailed Mapping Data section, below, for source of this data.
Target / Docking site For insertion progenitors of the type "Replacement descendant of (target)", defined as "progenitor replaced at original location, recombination event (target)", the insertion progenitor is also indicated in this field. See the section below "Progenitor(s) within the Genome".
Map (GBrowse) A GBrowse thumbnail graphic showing the location of the insertion in the genome. The insertion of interest is highlighted in yellow. This map is present only for insertions for which the site of insertion has been mapped to the sequenced genome. Insertions are indicated by blue triangles (which indicate orientation of the insertion) or diamonds (if orientation is not known). See also the GBrowse evidence tiers help document.

The "GBrowse" link goes to a fully interactive GBrowse view of the same region. Note that options are available in GBrowse to view the subset of transgenic insertions present in stocks available from the Bloomington, Kyoto, or Harvard stock centers. These options are found in the "Select Tracks" page (one of the upper left blue links on the GBrowse page) in the "Mapped Mutations" section.

Data on Genetic Line

Fields in this section are attributed data fields, meaning they include citations for the sources of the data.

Line ID The line identification number used by one of the large-scale gene disruption projects (eg., the BDGP, the GDP, or DrosDel), if relevant. A line identification number refers to an isolated genetic line, and thus may apply to more than one insertion, if multiple insertions are co-isolated.

Progenitors within the Genome

Fields in this section are attributed data fields, meaning they include citations for the sources of the data.

If the insertion that is subject of report is derived from a previously existing insertion, the FlyBase symbol for the originating insertion is indicated here (hyperlinked to the relevant Insertion Report). Progenitors are classified into 4 types: (1) "Transposed descendant of" defined as progenitor at distinct location, transposition event; (2) "Recombinant descendant of (donor)" defined as progenitor at distinct location, recombination event; (3) "Replacement descendant of (target): defined as progenitor replaced at original location, recombination event (target); (4) "Modified descendant of" defined as progenitor modified at original location. Categories 2 and 3 may both be reported, when the original transposon in an insertion is replaced with a new transposon using recombination with another insertion within the genome.
