March 2021: MaizeGDB qTeller now has data for version 5 of B73 and the NAM Founders! Select either "B73v5 [NAM Consortium]" or "NAM Founders [NAM Consortium]" under the drop-down menus above.

October 2019: MaizeGDB qTeller has a new look! Now we can compare expression and abundance under the menu 'Compare RNA & Protein'.

NAM Expression for Genes in an Interval

Retrieve FPKM information for all genes within specified genomic coordinates.

NOTE: The Diepenbrock 2017 bioproject does not include reads for Ki11 or M162W, and NC358 and CML228 do not include all tissue types.

  • About the NAM founder genomes
  • About B73 version 5
  • Select genomic interval

    To find the FPKM expression values of genes within a genomic interval, select a genome, select a chromosome, then enter the genome start and stop positions of your interval.

    To select expression for all the genes in the genome, select "All Chromosomes" and leave start and end positions blank.
