- SUMMARY_CNL_KSUM_EST_SSR_MARKER.xls Updated, 1 Mar
Overall functional marker information including primer sequences.
(Please note: Some cnl probes have one primer in
common, to amplify SSRs from the same supercluster in different species.
So check to be sure you don't order the same primer more than once.)
The first two sheets are organized not by individual rows but by blocks of
rows corresponding to the superclusters (SpCl) of EST contigs from Wheat (W),
Barley, Rice, Maize and Sorghum. Data in some columns refers to the SpCl
itself, in other columns to the particular row.
Hovering your mouse over the column headers in these tables will pop up a helpful comment.
- Sheet "ESTinfo"
- Sheet "primer"
For each SpCl multiple primer sequences are given, each with a Primer Name.
The primer pairs tested are given by name in the Primer Combination column.
- Sheet "PCR"
Results (amplification or not) of the named Primer Combinations in barley,
maize, rice and wheat.
- KSU_EST_SSR.xls Updated
Simpler, row-organized. Data for individual ESTs, not superclusters.
- Sheet "EST_info"
Note: Some primer pairs are derived from the same EST contig. See the
"Cornell SpCl" column to help identify these.
- Sheet "PCR"
Map locations (chromosome) and map scoring data for wheat Synthetic × Opata
and rice IR64 × Azucena.
- Sheet "POLY"
Polymorphism and chromosome locations for the wheat and rice genetic maps,
plus chromosome locations in Chinese Spring nulli-tetrasomics.
- Sheet "WHEAT" -- mapping scores.
- Sheet "RICE" -- mapping scores.
Wheat Synthetic x Opata map figure with these EST-SSRs added.
Rice IR64 x Azucena map figure with these EST-SSRs added.
