Consensus QTLs for drought tolerance and agronomic traits in rice

Moragues M., Sorrells M.E.

A database containing flanking markers for 1678 QTLs for components of drought tolerance and agronomical traits in rice from 42 publications was constructed. These QTLs corresponded to 40 traits that included morphophysiological traits related to drought tolerance such as osmotic adjustment, carbon isotope discrimination, leaf drying, and leaf rolling, yield, yield components, root traits and plant height and phenology, which were detected among a wide range of environments (99 in total), and 29 mapping populations from 39 parent lines. We located the flanking markers in the rice genome (Gramene Annotated Nipponbare Sequence 2006 searching them in the feature name database. For those markers that could not be located, the genebank sequence was analyzed by BLAST using the rice genomic sequence, and the location of the most homologous sequence was recorded. When more than one sequence was found or the marker sequence was not available (i.e. AFLP), we used the closest marker in the map of origin and followed the same steps described above. If no marker was close enough in the original map, the CMap tool was used to compare the original map to either the Cornell SSR 2001 map or the JRGP RFLP 2000 to find other markers in the same region that could be located in the rice sequence. Genomepixelizer was used to visualize the QTL map.
