Wild cards

When you use a search tool in FlyBase you can add the asterisk character * to the beginning or the end of a search term. This is recognised as a wild card and will find all terms that contain your search term at the beginning or end of a "word" respectively. You can also flank your search term with wild card characters to find all terms containing your search term.

For example, in QuickSearch you can find the genes that start with ft by entering ft*. The result of this search lists as you would expect fat (ft) and fushi tarazu (ftz), which you can see if you press "Show all hits", as well as fruitless (fru), because it is has the synonym fty. If you are interested in GAL4 or GFP lines select the data class "stocks" and enter the search term surrounded by wild card characters, for example *GFP*. In fact, we recommend using wild card characters here because often the search term may be part of a more complex term such as P{w[+mC]=UAS-GFP.nls}8.

Similarly, in TermLink searching for the term pup* finds any term that starts with pup (eg pupa, pupal dorsal branch), while searching with *pup* finds any term with pup anywhere within it (eg pupa, pupal dorsal branch, but also prepupa, non-functional pupal spiracle).
