Genome-wide development of transposable elements-based markers in foxtail millet and construction of an integrated database.

Yadav CB, Bonthala VS, Muthamilarasan M, Pandey G, Khan Y, Prasad M - DNA Res. (2014)

Bottom Line: Transposable elements (TEs) are major components of plant genome and are reported to play significant roles in functional genome diversity and phenotypic variations.A total of 30,706 TEs were identified and classified as DNA transposons (24,386), full-length Copia type (1,038), partial or solo Copia type (10,118), full-length Gypsy type (1,570), partial or solo Gypsy type (23,293) and Long- and Short-Interspersed Nuclear Elements (3,659 and 53, respectively).A total of 134 Repeat Junction Markers were screened in 96 accessions of Setaria italica and 3 wild Setaria accessions of which 30 showed polymorphism.

DSU039F8: Screenshots of foxtail millet Transposable Elements-based Marker Database. (A) Home page, (B) the details of a Copia-type retrotransposon displayed and (C) details of primers present in a Copia-type retrotransposon.

Mentions: Using the three-level schema of Apache, PHP and MySQL, open access Foxtail millet Transposable Element-based Marker Database (FmTEMDb; http://59.163.192.83/ltrdb/index.html) was constructed (Fig. 8). The database is a repository of complete TE data along with respective marker information. The details of TEs can be searched using six different search criteria such as TE IDs, type of TE, chromosome, etc. For each TE, the database will provide preliminary information of TE ID, chromosomal location, orientation of the coding strand, subclass (if any) and hyperlinks to retrieve the primers and view the physical map. Under primer details, the database will display the primer type, junction, TE type, TE source, strand orientation, start and end position of primers, melting temperature and GC percentage. The CMap feature of FmTEMDb allows the interactive visualization of physical and comparative map of TEs (Fig. 9). The map could be browsed either by type of TE or chromosome-wise. Further, all the data stored in the database are available for download. Although the database is user friendly, a tutorial is also provided (Supplementary Fig. S12).Figure 8.
