FlyBase:Combination Report
Last Updated: 13th Dec 2024
The Split System Combination report displays curated information for split driver lines, where two (or more) hemidrivers are combined to restrict functional driver expression to the intersection of the hemidriver expression patterns. These are predominantly split-GAL4 system combinations using a DBD and AD line currently, but more complex combinations may be included in the future.
General Information
| Symbol | The valid symbol that is used in FlyBase for the combination. |
| Feature type | The type of feature described in the report. In this case, "split system combination". |
| FlyBase ID | The Primary FlyBase identifier, used to uniquely identify the split system combination in the database. |
| Component alleles | The FlyBase symbols of the alleles comprising the given combination. Clicking on an allele symbol will take you to the relevant Allele Report. |
Combination components
Expression Data
| Reporter Expression | A three column table with the headings Stage, Tissue/Position, and Reference. Each row in the table represents one distinct expression pattern defined by time of expression (Stage) and by location of expression (Tissue/Position). Each distinct expression pattern is attributed to the reference that reported it. Developmental stages and anatomical parts are described using controlled vocabulary (CV) terms (for valid CV terms, see the Vocabularies search page).
The table is subdivided by the assay, when appropriate. |
| Additional information |
Free-text curated descriptions of expression patterns, sorted by reference. |
Stocks
A list of experimental lines relating to this combination that are available for order from public stock centers.

Synonyms and Secondary IDs
Reported As
| Symbol Synonym | A list of symbols that have been used in the literature, or by FlyBase, to describe the combination. |
| Name Synonym | A list of names that have been used in the literature, or by FlyBase, to describe the combination. |
Secondary FlyBase IDs
A list of Secondary FlyBase identifier numbers of the combination.
If a combination has a secondary identifier number, it generally indicates that at some point it has been merged with or split from other entries in the database.
