Intron Polymorphism (IP) is designed by intron position. In order to develop IP markers, a program with Perl script was used to find the IP position through the gff annotation of genome.
IP and PIP Primer
The Primer was designed by the aimed sequence, using a Perl script and eprimer3, and all Primers were tested by e-PCR. All these primers were also collected in PSID. You also can search and download the data as you want through this link.
To explore the usage of IP markers, a predict of EST sequence was made, all Primers that may be exist have been collected in the database. You can search and download them from the ip search if you need it. (Primer)
IP and PIP information
All information including intron, exon, primer and productions of IP and PIP was collected and insert into the PSID, you can search and download them through this link. (information)
