This webpage hosts our tentative mapping between Medicago truncatula Affymetrix Probe-sets vs. IMGAG 2.0 genes and Medicago Gene Index 8.0 unigenes.

The Medicago truncatula Affymetrix gene chip was developed based on Medicago truncatula Gene Index 8.0 release and pre-IMGAG 1.0 gene prediction. We believe that re-analyzing Affymetrix Probe-sets vs. newly released IMGAG gene 2.0 and original Medicago Gene Index 8.0 will be beneficial to legume community to get the most out of our recent published Medicago truncatula Gene Expression Atlas.

 

1. Original Data with Links:

2. Analysis and Discussion:

  • 20080227_imgag_cdna.fasta: The UTRs+CDs (mRNA) of predicted genes in Medicago 2.0, downloaded from above internal link and further parsed using an internal script.
  • MtAffyprobeset_MTGI80_IMGAG20_mapping0326.ppt: The PowerPoint presentation generated for discussion and evaluation of the quality of M.t. Affymetrix probe-set vs. IMGAG 2.0 and MTGI 8.0 gene mapping.

3. Mapping results:

  • probe_mapping.xls: tentative mapping between probe-sets, IMGAG genes and Unigenes, analyzed by the Zhao bioinformatics lab.
 
 

Note: Although, we've done our best to ensure the quality of mapping between Affymetrix probe-sets and IMGAG 2.0 / MTGI 8.0 genes, please consider this as a tentative mapping release. We advise to use them at your own risk.
